600/1000V Multicore Cables 3x120 1x70mm2 3+1 Multiple Cores Pure Aluminum Power Cable

The specification parameters of the 600/1000V 3x120 1x70mm² 3+1 multi-core pure Aluminum Power Cable are the core foundation of its performance and application. Each parameter is precisely designed and strictly controlled to ensure that the cable plays a stable and reliable role in low-voltage power transmission.

In terms of conductor specifications, the cable adopts a 3+1 multi-core structure, with 3 conductors having a cross-sectional area of 120mm² and the other one having a cross-sectional area of 70mm², all made of pure aluminum. The 120mm² cross-sectional area is determined according to the current-carrying capacity requirements of the phase lines in three-phase alternating current, which can meet the requirements of large-power power transmission. It ensures that in scenarios with large electrical loads such as industrial and commercial fields, power transmission will not cause problems like overheating due to insufficient conductor cross-sectional area. The 70mm² conductor, serving as the neutral line, is designed considering the circulation demand of unbalanced three-phase currents, which can effectively balance the three-phase currents and ensure the stable operation of the power system. The diameter of the pure Aluminum Conductors is precisely calculated. The 3 conductors of 120mm² have the same diameter, while the 70mm² conductor has a slightly smaller diameter. This size difference not only meets different conductive needs but also facilitates the formation of a compact structure during multi-core stranding.

The rated voltage parameter is 600/1000V, which clearly defines the applicable voltage range of the cable. 600V indicates the phase voltage that the cable can withstand, and 1000V is the line voltage. It conforms to the voltage standards of low-voltage distribution systems, enabling it to be widely used in power transmission scenarios with a rated voltage of 1000V and below. The setting of this voltage level not only ensures the safety of the cable during normal operation but also meets the power needs of most low-voltage electrical equipment and places.

The specifications of the insulation layer are also crucial. The thickness of the insulation layer is determined according to the rated voltage and service environment of the cable, usually ranging from 0.8mm to 1.2mm. When cross-linked polyethylene (XLPE) is used as the Insulation Material, its insulation thickness can effectively resist the electric field strength under 600/1000V voltage, preventing insulation breakdown. If polyvinyl chloride (PVC) is used as the insulation material, its insulation thickness will be appropriately adjusted according to the insulation performance of the material to ensure the same insulation effect. The insulation layer also has clear color distinctions. Generally, phase A is yellow, phase B is green, phase C is red, and the neutral line is blue, which facilitates accurate identification of each phase conductor during installation and maintenance.

The specifications of the sheath layer are mainly reflected in its thickness and material performance. The thickness of the PVC Sheath layer is usually 1.2-1.8mm, which has sufficient mechanical strength to withstand certain external impacts and wear. Its performance parameters such as density, tensile strength, and elongation at break all meet relevant standards, ensuring that the sheath layer can effectively protect the internal conductors and insulation layer under different environmental conditions. In addition, the outer diameter of the sheath layer is also an important parameter. The overall outer diameter of the cable is comprehensively determined according to the sizes of the conductor, insulation layer, and sheath layer, generally ranging from 25mm to 30mm. This size facilitates the installation of the cable in laying environments such as pipes and cable trays.

The 600/1000V 3x120 1x70mm² 3+1 multi-core pure aluminum power cable, relying on its unique Structure and Performance advantages, has irreplaceable characteristic uses in many fields and can meet power transmission needs in different scenarios.

In the field of industrial production, this cable plays an important role. There are various types of production equipment in factory workshops, most of which are three-phase electrical equipment, such as CNC machine tools, punching machines, blowers, etc. These equipment have high requirements for the stability and transmission efficiency of electricity. The 3+1 multi-core design is just suitable for the three-phase four-wire industrial distribution system. The 3 conductors of 120mm² can provide sufficient three-phase power for the equipment, and the 70mm² neutral line can balance the three-phase currents, avoiding abnormal operation of the equipment due to three-phase imbalance. At the same time, the light weight of the pure aluminum conductor of the cable reduces the difficulty of laying in the complex environment of the workshop, facilitating wiring shuttlebetween equipment and meeting the flexible power layout needs in the workshop. In addition, the wear resistance and oil resistance of its PVC sheath layer can adapt to the environment where oil stains and mechanical friction may exist in the workshop, prolonging the service life of the cable.

Commercial places are also important application scenarios for this cable. In commercial buildings such as large shopping malls, office buildings, and hotels, power demand involves lighting, air conditioning, elevators, office equipment, etc., with large electrical loads and widely distributed electrical equipment. This cable can be used as the main cable in the building, transmitting power from the distribution room to the distribution boxes on each floor, and then distributing it to various electrical terminals through branch cables. The 3 conductors of 120mm² can meet the large three-phase power demand of commercial places, ensuring the normal operation of high-power equipment such as air conditioning systems and elevators; the 70mm² neutral line can cope with the unbalanced current generated by single-phase electrical equipment. Its multi-core structure reduces the number of cables laid, saves wiring space in the building, and makes the electrical system of the building more neat and orderly. Moreover, the flame retardant performance of the cable (if using a flame-retardant PVC sheath) can improve the fire safety level of commercial places, adding a sense of security to crowded environments.

In the field of civil construction, this cable also has a wide range of applications. The power supply in residential communities needs to cover the daily electricity use of each household, including household appliances, lighting, etc. As the main cable of the community distribution system, this cable can transmit power from the community substation to the distribution boxes of each building, and then distribute it to each household. The 3+1 multi-core design adapts to the coexistence of three-phase and single-phase equipment in residential electricity use. It can not only supply power to three-phase equipment such as elevators and water pumps in the building but also provide power to single-phase appliances in residents' homes through the neutral line. The light weight of the pure aluminum conductor reduces the difficulty of laying in the underground pipe network or walls of the community, reducing construction costs. At the same time, the aging resistance of its insulation layer and sheath layer can ensure the stable operation of the cable during long-term use, providing a reliable guarantee for residents' daily electricity use.

Outdoor temporary power supply scenarios are also inseparable from the support of this cable. On construction sites, various large mechanical equipment such as tower cranes, concrete mixers, and electric welders are used during construction, which require temporary high-power power supply. The lightweight characteristic of this cable makes it easy to transport and temporarily lay, and can quickly build a power transmission line from the temporary distribution box to the construction equipment. The 3 conductors of 120mm² can meet the three-phase power demand of construction equipment, ensuring the normal operation of the equipment. At large outdoor event venues, such as concerts and sports events, it is also necessary to temporarily build a power system to supply power to stage lighting, audio, broadcasting equipment, etc. This cable can also rely on its adaptability and convenience to ensure stable power supply during the event. After the event, the cable can be easily recycled for reuse, improving resource utilization.

The agricultural production field can also see the presence of this cable. In modern agricultural greenhouses, power support is needed for temperature control equipment, irrigation systems, lighting, etc. These equipment are mostly three-phase or single-phase electrical equipment. This cable can be buried around or underground in the greenhouse, transmitting power from the agricultural distribution room to the distribution box in the greenhouse to supply power to various equipment. Its weather resistance and corrosion resistance can adapt to the humid environment in the greenhouse and changes in the external climate, ensuring long-term stable operation. At the same time, the economy of pure Aluminum Conductors can reduce the cost of power facilities in agricultural production, which is in line with the economic benefits of agricultural production.

The 600/1000V 3x120 1x70mm² 3+1 multi-core pure aluminum power cable fully considers factors such as performance, cost, and ease of use in material selection and style design, making it have unique advantages in the field of low-voltage power transmission.

In terms of materials, the conductor uses high-purity pure aluminum with a purity of more than 99.7%. High-purity aluminum has good electrical conductivity. Although its conductivity is lower than that of copper, it can meet the requirements of low-voltage power transmission. At the same time, the density of pure aluminum is only 2.7g/cm³, which is much lower than that of copper (8.9g/cm³). This greatly reduces the overall weight of the cable, lowering the labor and equipment costs during transportation, laying, and installation. To improve the performance of the pure aluminum conductor, it will be annealed. By heating to a certain temperature and then slowly cooling, the internal stress generated in the processing of the aluminum conductor is eliminated, and its Flexibility and ductility are improved, so that the cable is not easy to break during bending and laying. In addition, a dense oxide film will form on the surface of pure aluminum, which can prevent further oxidation of aluminum, enhance the oxidation resistance and corrosion resistance of the conductor, and prolong the service life of the cable.

There are mainly two material choices for the insulation layer: cross-linked polyethylene (XLPE) and polyvinyl chloride (PVC). XLPE Insulation Material has excellent electrical performance, with high insulation resistance and low dielectric loss. It can maintain stable insulation performance at relatively high temperatures, with a working temperature of up to 90℃, and has strong aging resistance and a long service life. At the same time, XLPE material has good mechanical strength and chemical corrosion resistance, and can adapt to various complex environments. PVC Insulation Material has good insulation performance and processing performance, with a relatively low price. Its working temperature is generally around 70℃, which is suitable for scenarios with not too high ambient temperatures. PVC Insulation material also has certain flame retardant performance, which can delay the spread of flames to a certain extent.

The sheath layer is made of polyvinyl chloride (PVC). The PVC sheath has good mechanical properties, with high tensile strength and large elongation at break, which can withstand certain external impacts and stretching, protecting the internal conductors and insulation layer from damage. It has strong corrosion resistance and can resist the erosion of acids, alkalis, salts, and other chemical substances, adapting to different environmental conditions. The PVC sheath also has good weather resistance, which can maintain stable performance under the action of natural environmental factors such as sunlight, rain, and temperature changes. In addition, PVC materials can be made to have flame retardant properties by adding flame retardants and other additives, improving the safety of the cable in case of fire.

In terms of style, the cable is a round multi-core stranded style. The 3 conductors of 120mm² and 1 conductor of 70mm² are each wrapped with an insulation layer and then stranded together according to a certain stranding pitch and direction to form a cable core. The stranding pitch is usually 16-20 times the outer diameter of the cable. A reasonable stranding pitch makes the cable have good flexibility, facilitating bending and laying in narrow spaces. The outside of the Stranded Cable core will be filled with some inert materials, such as polypropylene rope or non-woven fabric. These filling materials can fill the gaps between the conductors, making the cable core structure more round and stable, and at the same time play a buffering role, reducing mutual friction between conductors during transportation and laying. The outside of the filling layer is wrapped with a PVC sheath layer to form a complete cable structure, with an overall round appearance and a smooth surface, facilitating pipe threading and laying.

The color design of the cable not only conforms to industry standards but also has practicality. The insulation layer uses four colors of yellow, green, red, and blue to distinguish conductors of different phases, which is convenient for installers to identify and wire, avoiding wiring errors. The color of the sheath layer is usually black. Black has good light resistance, which can reduce the aging effect of sunlight and ultraviolet rays on the sheath layer, and black is also relatively dirt-resistant, which can keep the appearance of the cable clean.

In addition, according to different usage needs, the cable can also provide some special styles. For example, for environments requiring rodent and ant prevention, rodent and ant repellents can be added to the PVC sheath layer to prevent the cable from being damaged by rodents and ants; for laying scenarios that need to bear large tensile forces, a layer of Steel Tape or steel wire armor can be added inside the sheath layer to improve the tensile strength and mechanical protection performance of the cable.

The production process of the 600/1000V 3x120 1x70mm² 3+1 multi-core pure aluminum power cable is complex and sophisticated. Each link from raw material processing to finished product inspection needs to be strictly controlled to ensure that the quality of the cable meets relevant standards and usage requirements.

Conductor production is the first step in cable manufacturing. First, high-purity aluminum ingots are smelted to remove impurities, obtaining aluminum liquid that meets the purity requirements. The aluminum liquid is cast into aluminum rods through a continuous casting machine. During the casting process, parameters such as casting temperature and cooling rate must be strictly controlled to ensure that the grain structure of the aluminum rod is uniform and the mechanical properties are good. The aluminum rod is drawn through multiple passes of a wire drawing machine to gradually form Aluminum Wires with the required diameter. During the wire drawing process, appropriate lubricants need to be used to reduce friction between the Aluminum Wire and the die, avoiding damage to the surface of the aluminum wire. At the same time, the wire drawing speed and tension must be controlled to ensure the dimensional accuracy and stable mechanical properties of the aluminum wire. The drawn aluminum wire needs to be annealed. The aluminum wire is heated to 300-400℃ and then slowly cooled to eliminate internal stress generated during the wire drawing process, improving the flexibility and conductivity of the aluminum wire. Finally, multiple aluminum wires are stranded together according to certain rules to form aluminum conductors with cross-sectional areas of 120mm² and 70mm² respectively. During the stranding process, the roundness and tightness of the conductor must be ensured to ensure the uniformity of its conductivity.

The extrusion of the insulation layer is a key link to ensure the electrical performance of the cable. The extrusion process varies slightly depending on the insulation material used. If XLPE is used as the insulation material, first, the XLPE particles are pretreated to remove moisture and impurities. The pretreated XLPE particles are added to the extruder, and the material is melted and plasticized in the extruder through heating and the shearing action of the screw. The molten XLPE material is uniformly coated on the surface of the aluminum conductor through an extrusion die to form an insulation layer. During the extrusion process, the extrusion temperature (usually 120-150℃), pressure, and speed must be accurately controlled to ensure that the insulation layer has uniform thickness, a smooth surface, and is tightly bonded to the conductor. The extruded Insulated Wire core needs to undergo cross-linking treatment, usually using warm water cross-linking or steam cross-linking. The insulated wire core is placed in a high-temperature and high-pressure water or steam environment to make the XLPE molecules undergo a cross-linking reaction to form a network structure, thereby improving the heat resistance, mechanical strength, and aging resistance of the insulation layer. If PVC is used as the insulation material, PVC resin is mixed with plasticizers, stabilizers, and other additives in proportion and then added to the extruder. After melting and plasticizing, it is coated on the surface of the conductor to form an insulation layer, with an extrusion temperature generally ranging from 160℃ to 180℃.

Multi-core stranding is the process of combining 4 insulated wire cores into a cable core. Before stranding, each insulated wire core must be inspected for appearance and size to ensure that its quality meets the requirements. Then, the 3 insulated wire cores of 120mm² and 1 insulated wire core of 70mm² are stranded on a stranding machine according to a certain stranding direction (usually right-hand) and stranding pitch. The size of the stranding pitch will affect the flexibility and structural stability of the cable and needs to be reasonably set according to the specifications of the cable. During the stranding process, the tension of each wire core must be uniform to avoid loosening, twisting, and other phenomena. The outside of the stranded cable core needs to be filled with materials. The selection of filling materials should consider their corrosion resistance and flexibility to fill the gaps between the wire cores, making the cable core structure more round and stable.

The extrusion of the sheath layer is the last important process in cable production. PVC resin is mixed with stabilizers, plasticizers, flame retardants, and other additives and then added to the extruder. After being heated, melted, and plasticized, it is coated on the outside of the stranded cable core through an extrusion die to form a sheath layer. During the extrusion process, the extrusion temperature (160-190℃), pressure, and speed must be controlled to ensure that the sheath layer has uniform thickness, a smooth surface, and is tightly bonded to the cable core. The thickness of the sheath layer should be designed according to the service environment and protection requirements of the cable to ensure that it can effectively protect the internal structure.

After the cable production is completed, a series of strict quality inspections are carried out. Electrical performance testing is a key part, including insulation resistance testing using a megohmmeter to measure the insulation resistance between conductors and between conductors and the sheath, ensuring it meets the standard value (usually not less than 100MΩ). AC voltage withstand testing is also conducted, applying a test voltage higher than the rated voltage (such as 3000V for 5 minutes) to check for breakdown or flashover phenomena, verifying the insulation layer's ability to withstand overvoltage.

Mechanical performance testing is equally important. Tensile strength and elongation at break tests are performed on the insulation and sheath materials. For PVC materials, the tensile strength is generally required to be not less than 12MPa, and the elongation at break not less than 150%, ensuring the materials have sufficient toughness and durability to resist external forces during use. Additionally, impact resistance testing may be conducted, using a hammer to strike the cable sample under specified conditions to check for cracks or damage to the sheath and insulation layers.

Flame retardant performance testing is essential if the cable is designed to be flame retardant. It is carried out in accordance with relevant standards (such as IEC 60332). The cable sample is subjected to a specified flame intensity and burning time, and parameters such as the burning length, self-extinguishing time, and whether the flame spreads to the clamp are observed to evaluate its flame retardant effect.

Appearance inspection is performed visually and with measuring tools. The cable's surface should be smooth, without defects such as scratches, bulges, bubbles, or cracks. The thickness of the insulation and sheath layers is measured at multiple points using a micrometer to ensure uniformity and compliance with design requirements. The overall diameter of the cable is also checked to meet the specified range, facilitating laying and installation.

Length measurement is conducted using a length counter during the production process, and random checks are performed after production to ensure the actual length meets the customer's order requirements, with a tolerance generally within ±0.5%.

Only after passing all these inspections is the cable considered qualified and allowed to leave the factory, ensuring that each batch of products meets the quality standards and can reliably serve customers.

The packaging of the 600/1000V 3x120 1x70mm² 3+1 multi-core pure aluminum power cable is designed to provide comprehensive protection during transportation, storage, and handling, while also facilitating management and use by customers.

For cables with longer lengths (typically 50 meters or more), cable reels are the primary packaging choice. There are two main types of cable reels: wooden and steel. Wooden reels are cost-effective and relatively lightweight, consisting of two circular wooden end discs and a central wooden barrel. The end discs are reinforced with wooden ribs to enhance their load-bearing capacity, ensuring they can support the weight of the cable without deformation. The diameter of the central barrel is designed based on the cable's minimum bending radius, usually at least 10 times the cable's outer diameter, to prevent damage to the insulation and conductor due to excessive bending during winding. Wooden reels are suitable for short-distance transportation and small-batch deliveries. To improve their durability, the wood is often treated with anti-corrosion agents to resist moisture and decay in humid environments.

Steel cable reels, on the other hand, offer superior strength and durability. Constructed from welded steel plates, they undergo surface rust-proof treatments such as galvanizing or painting, making them suitable for long-distance transportation, large-batch shipments, and harsh environmental conditions. The robust structure of steel reels ensures they can withstand the rigors of long-distance shipping, including vibrations, impacts, and varying weather conditions, providing maximum protection for the cable.

Before winding the cable onto the reel, a layer of polyethylene plastic film is wrapped around the cable's outer surface. This film acts as a barrier against moisture, dust, and dirt, preventing contamination and corrosion of the cable's sheath and insulation layers. For cables intended for long-term storage or transportation in extremely humid environments, an additional layer of burlap or waterproof canvas is wrapped over the plastic film to enhance moisture resistance.

The cable is wound onto the reel in an orderly and tight manner, with each turn neatly aligned to avoid overlapping, crossing, or loosening. This careful winding prevents friction between cable layers during transportation, which could otherwise cause abrasion to the sheath. Once winding is complete, the cable is secured to the reel using high-strength plastic strapping, applied at regular intervals around the circumference to ensure the cable remains firmly in place during handling and transportation.

Each cable reel is equipped with metal lifting lugs on its end discs, positioned to allow safe and balanced lifting using cranes or forklifts. This design facilitates efficient loading and unloading operations, reducing the risk of damage to the reel or cable.

A comprehensive product label is affixed to a prominent position on the reel. The label includes essential information such as the cable's model (600/1000V 3x120 1x70mm²), type (3+1 multi-core pure aluminum power cable), length, net weight, gross weight, production date, batch number, manufacturer's name, address, and contact information, as well as compliance with relevant standards (e.g., IEC, GB). Additionally, handling instructions and warning symbols such as "Handle with Care," "Keep Dry," "Do Not Drop," and "Maximum Stacking Height" are printed on the label to guide proper transportation and storage.

For shorter cable lengths (typically less than 50 meters), coiled packaging is used. The cable is tightly wound into a coil with a diameter of 40-60cm, secured with plastic ties at multiple points to maintain its shape. The coil is then wrapped in plastic film and placed in a sturdy cardboard box or woven bag. These packages also include product labels with the same detailed information as the reels, ensuring traceability and easy identification.

The packaging process adheres to strict quality control measures to ensure that each cable is adequately protected, minimizing the risk of damage during transit and storage, and ensuring customers receive the product in perfect condition.

The transportation of the 600/1000V 3x120 1x70mm² 3+1 multi-core pure aluminum power cable requires careful planning and execution to ensure the product arrives at its destination in optimal condition. A series of measures are implemented to safeguard the cable during transit, considering factors such as distance, mode of transport, and environmental conditions.

Before transportation, a thorough inspection of the packaging is conducted. For cable reels, this includes checking the integrity of the wooden or steel structure, ensuring the end discs are securely attached to the central barrel, and verifying that the lifting lugs are in good condition. The strapping securing the cable to the reel is inspected to ensure it is tight and undamaged. For coiled cables in boxes or bags, the packaging is checked for tears, punctures, or other damage that could expose the cable to moisture or physical harm. Any damaged packaging is repaired or replaced before the cable is shipped.

The choice of transportation mode depends on factors such as the distance to the destination, the quantity of cables, and customer requirements. For short-distance transportation (within a city or region), road transport using trucks is typically used. The cable reels or coiled packages are loaded onto the truck using forklifts or cranes, ensuring they are positioned securely to prevent movement during transit. When loading multiple reels, they are placed with sufficient spacing to avoid collision, and wooden blocks or wedges are used to stabilize them. The reels are oriented such that their central axis is parallel to the truck's direction of travel, minimizing the risk of tipping during acceleration or braking.

For long-distance domestic transportation, trucks or railway freight may be used. Railway transport is often preferred for large quantities due to its stability and lower risk of vibration-related damage. Cable reels are loaded onto flatbed railcars and secured using chains or steel cables attached to the railcar's anchor points. Similar to road transport, proper spacing and stabilization measures are implemented to prevent movement.

For international shipments, sea freight is the primary mode. Cable reels are loaded into shipping containers, with attention to weight distribution to ensure the container is balanced. The reels are secured to the container's floor using twist locks or straps to prevent shifting during the voyage, which can involve rough seas and significant movement. Climate-controlled containers may be used for cables sensitive to extreme temperatures or humidity, though the cable's robust packaging typically provides sufficient protection.

During transportation, environmental factors are closely monitored. In cases of rain, snow, or high humidity, the cable reels or packages are covered with waterproof tarpaulins to prevent moisture ingress. Extreme temperatures are also a consideration; in hot weather, precautions are taken to avoid prolonged exposure to direct sunlight, which could cause the sheath material to soften or degrade. In cold weather, efforts are made to prevent the cable from becoming brittle due to freezing temperatures, though the cable's materials are designed to withstand a wide range of temperatures.

Handling procedures during loading and unloading are strictly enforced to prevent damage. Operators are trained to use proper lifting techniques, ensuring that the lifting equipment is correctly attached to the reel's lifting lugs (for reels) or that coiled packages are lifted evenly. Dropping or dragging the cable is strictly prohibited, as this can damage the sheath, insulation, or conductor.

Throughout the transportation process, a tracking system is used to monitor the shipment's progress. Customers are provided with tracking information, allowing them to anticipate the arrival time. In the event of delays or unexpected issues (such as traffic accidents, mechanical breakdowns, or weather-related disruptions), the transportation provider and customer are notified promptly, and alternative arrangements are made if necessary.

Upon arrival at the destination, the cable is unloaded using appropriate equipment and inspected by the customer or their representative. The packaging is checked for signs of damage during transit, and the cable's label is verified to ensure the correct product has been delivered. Any issues or discrepancies are documented and addressed promptly by the manufacturer or logistics provider.

By following these transportation protocols, the risk of damage to the 600/1000V 3x120 1x70mm² 3+1 multi-core pure aluminum power cable is minimized, ensuring it arrives in good condition and is ready for installation and use.

The shipping process for the 600/1000V 3x120 1x70mm² 3+1 multi-core pure aluminum power cable is a well-coordinated sequence of activities designed to ensure timely, accurate, and efficient delivery to customers. This process involves close collaboration between the sales, production, warehouse, and logistics teams to meet customer expectations and maintain high service standards.

The sales team reviews the order details, including the cable model, specifications, quantity, delivery address, and requested delivery date, to ensure all information is accurate and complete. Any discrepancies or special requirements (such as expedited shipping or specific packaging) are clarified with the customer before proceeding.

The order information is then transmitted to the production department, which checks if the required cable is in stock or needs to be manufactured. If the cable is in stock, the warehouse is notified to prepare the goods. If production is necessary, the production schedule is adjusted to prioritize the order, ensuring it is completed within the required timeframe. Once production is finished and the cable has passed quality inspection, it is transferred to the warehouse.

Warehouse personnel are responsible for picking and preparing the cable for shipment. They locate the specified cable in the warehouse, verify its model, specifications, and batch number against the order, and conduct a visual inspection to ensure there are no visible defects. The cable is then packaged according to the standard packaging procedures (as described in the packaging section), with special attention to securing the cable to reels or packaging coils to prevent damage during transit.

After packaging, the warehouse team generates shipping documents, including a packing list, commercial invoice, bill of lading (for international shipments), and any required certificates (such as quality inspection certificates or compliance certificates). These documents are reviewed for accuracy, ensuring they match the order details and meet the requirements of the destination country or region (for international shipments).

The logistics team selects a suitable transportation provider based on factors such as the delivery location, shipment size, and customer's delivery timeline. A contract is signed with the transportation provider, outlining the terms and conditions, including responsibilities for loss or damage, delivery deadlines, and transportation costs. The logistics team communicates the shipment details to the transportation provider, including the pickup location, delivery address, and any special handling instructions.

On the scheduled pickup date, the transportation provider collects the cable from the warehouse. A formal handover process is conducted, during which the warehouse personnel and the driver inspect the shipment together to confirm the quantity, packaging condition, and documentation. The driver signs a delivery receipt acknowledging receipt of the shipment, which is retained by the warehouse for record-keeping.

Once the shipment is in transit, the logistics team monitors its progress using tracking systems provided by the transportation provider. Regular updates are provided to the customer, including the estimated time of arrival, current location of the shipment, and any potential delays. If a delay is anticipated, the customer is notified immediately, and efforts are made to resolve the issue and minimize the impact.

Upon arrival at the destination, the customer is contacted to arrange for delivery or pickup. The customer inspects the shipment upon receipt, checking the packaging for damage and verifying the quantity and condition of the cable against the packing list. If the customer is satisfied with the delivery, they sign a delivery confirmation document, which is returned to the logistics team as proof of receipt.

In the event of any issues during shipping, such as damaged goods, missing items, or delivery delays, the logistics team works closely with the transportation provider and the customer to resolve the problem. This may involve arranging for a replacement shipment, processing a claim for damages, or providing a refund, depending on the nature of the issue.

After successful delivery, the warehouse and logistics teams update their records to reflect the completion of the shipment. The sales team follows up with the customer to ensure they are satisfied with the delivery and the condition of the cable, gathering feedback to improve future shipping processes.

The entire shipping process is designed to be efficient, transparent, and customer-focused, ensuring that the 600/1000V 3x120 1x70mm² 3+1 multi-core pure aluminum power cable reaches the customer on time and in perfect condition.

For customers who require modifications to the cable (such as custom lengths, special sheath materials, or additional features), the sample service can also be used to evaluate prototypes of the modified product.

Overall, the sample service is a valuable tool for building trust between the manufacturer and the customer, ensuring that the customer makes an informed purchasing decision and is confident in the quality and suitability of the 600/1000V 3x120 1x70mm² 3+1 multi-core pure aluminum power cable for their application.

The manufacturer of the 600/1000V 3x120 1x70mm² 3+1 multi-core pure aluminum power cable is committed to providing comprehensive after-sales service to ensure customer satisfaction and support the long-term performance of the product. This service encompasses a range of activities, from technical support and troubleshooting to warranty coverage and maintenance guidance, designed to address any issues that may arise during the cable's lifecycle.

One of the key components of after-sales service is a clearly defined warranty policy. The cable typically comes with a warranty period of 1-5 years from the date of delivery, depending on the application and usage

conditions. The warranty covers defects in materials and workmanship that occur under normal operating conditions. If the cable fails within the warranty period due to such defects, the manufacturer will, at its discretion, repair, replace, or refund the cost of the defective product. To make a warranty claim, the customer must provide proof of purchase (such as an invoice or delivery receipt) and a detailed description of the issue, including photographs or test reports if applicable. The manufacturer reserves the right to inspect the defective cable to determine the cause of failure and verify the claim's validity.

Technical support is another vital aspect of after-sales service. A dedicated team of technical experts is available to assist customers with any questions or issues related to the cable's installation, operation, or maintenance. Customers can contact the technical support team via phone, email, or online chat during business hours. The team can provide guidance on proper installation techniques, including bending radius requirements, termination methods, and compatibility with other electrical components. They can also offer troubleshooting assistance for problems such as insulation breakdown, conductor overheating, or sheath damage, helping customers identify the root cause and implement effective solutions.

For more complex issues that cannot be resolved remotely, the manufacturer may arrange for a technical representative to visit the customer's site. This on-site support is particularly valuable for large-scale installations or critical applications where downtime must be minimized. The technical representative can conduct a thorough inspection of the cable and the installation environment, provide hands-on guidance, and work with the customer to develop a resolution plan.

In addition to troubleshooting, the after-sales service team provides proactive maintenance advice to help customers maximize the cable's lifespan. This includes recommendations on regular inspection schedules, cleaning procedures, and environmental controls (such as temperature and humidity management) to prevent premature aging or damage. The manufacturer may also offer training sessions for the customer's maintenance staff, covering topics such as cable inspection techniques, identifying early signs of degradation, and basic repair procedures.

Customer feedback is actively sought and valued as part of the after-sales service process. The manufacturer conducts regular follow-up surveys to assess customer satisfaction with the product and service. Any feedback, whether positive or negative, is used to identify areas for improvement in product design, manufacturing processes, or service delivery. Customers are encouraged to report any issues or suggestions, and the manufacturer strives to respond promptly and address concerns effectively.

In cases where the cable requires repair or replacement outside the warranty period, the manufacturer offers cost-effective repair services. The customer can send the defective cable to the manufacturer's repair facility, where it will be evaluated by technicians. A repair quote is provided, and upon customer approval, the necessary repairs are carried out using genuine parts. This option allows customers to extend the cable's lifespan at a lower cost than purchasing a new one.

The after-sales service team also maintains detailed records of each customer's purchase history, warranty claims, and service interactions. This information helps in providing personalized support, as the team can quickly access relevant details about the customer's specific cable model, installation date, and previous issues. It also enables the manufacturer to track trends in product performance and identify any recurring problems that may require design or production adjustments.

Overall, the after-sales service for the 600/1000V 3x120 1x70mm² 3+1 multi-core pure aluminum power cable is designed to be responsive, reliable, and customer-centric. By offering comprehensive warranty coverage, expert technical support, proactive maintenance guidance, and flexible repair options, the manufacturer ensures that customers can use the cable with confidence, knowing that any issues will be promptly and effectively addressed. This commitment to after-sales service not only enhances customer satisfaction but also builds long-term relationships based on trust and mutual success.
