The 1.5mm² and 2.5mm² specifications of PVC insulated single-core Copper Cables are precisely designed to meet the needs of different electrical scenarios, providing stable and reliable power transmission support for various medium and low-load circuits.

The conductor of the 1.5mm² cable is stranded with multiple strands of high-purity electrolytic Copper Wires with a diameter of 0.15mm. Through a scientific stranding process, the overall cross-sectional area of the conductor reaches 1.5mm². This multi-strand stranded structure not only enhances the Flexibility of the conductor but also effectively disperses the current, reducing losses caused by the skin effect. At room temperature, its DC resistance is ≤12.1Ω/km, and the low resistance value ensures minimal energy loss during current transmission. The allowable continuous current-carrying capacity of this specification cable is 16A, which is fully capable of meeting the power supply needs of lighting fixtures and small household appliances (such as table lamps, electric fans, TVs, set-top boxes, etc.). For example, a commonly used 40W fluorescent lamp in a household has a working current of approximately 0.18A. Even if multiple lamps work simultaneously, the total current is far lower than 16A, and the 1.5mm² cable can easily handle it.

The conductor of the 2.5mm² cable is stranded with thicker copper wires, with a single wire diameter larger than that of the 1.5mm² cable, and the overall cross-sectional area after stranding is 2.5mm². Its DC resistance at room temperature is ≤7.41Ω/km, and the reduction in resistance further reduces energy loss during current transmission. The allowable continuous current-carrying capacity is increased to 25A, which can meet the power demand of medium-power appliances such as air conditioners (generally 1-1.5 horsepower, with a working current of approximately 4-7A), electric water heaters (power of approximately 1500-2000W, working current of approximately 6.8-9.1A), and microwave ovens (power of approximately 800-1500W, working current of approximately 3.6-6.8A). Taking the simultaneous use of an air conditioner and an electric water heater as an example, the total current is approximately 10-16A, which is much lower than the 25A current-carrying capacity, and the 2.5mm² cable can stably ensure their power supply.

Both cables have a rated voltage of 300/500V. This voltage level can not only meet the needs of common 220V AC circuits in homes and offices but also withstand possible voltage fluctuations in daily power grid operation, providing sufficient voltage margin for circuit safety. When the grid voltage has a short-term increase or fluctuation, the cable will not have faults such as insulation layer breakdown due to voltage issues.

In terms of insulation layer thickness, the insulation layer of the 1.5mm² cable is 0.8mm, and that of the 2.5mm² cable is 0.9mm. A thicker insulation layer can provide more reliable insulation protection for the 2.5mm² cable to adapt to the larger current it carries and the possibly more complex electrical environment. The insulation resistance of both cables is ≥100MΩ. The high insulation resistance ensures that there is almost no current leakage in the cable under normal working conditions, effectively preventing electric shock accidents and ensuring electrical safety.

In addition, both cables comply with the GB/T 5023.3 standard certification, which means that their material selection, production processes, performance indicators, etc., have undergone strict inspections and meet the national quality standards, providing users with reliable quality assurance.

The 1.5mm² and 2.5mm² specifications of PVC insulated single-Core Copper cables play important roles in different scenarios with their respective performance characteristics, having distinct characteristic uses.

Due to its moderate current-carrying capacity and thin wire diameter, the 1.5mm² cable is widely used in lighting circuits of residential buildings and office buildings. In home decoration, the power supply lines of living room chandeliers, spotlights, bedroom downlights, ceiling lamps, kitchen and bathroom lighting fixtures, etc., mostly use 1.5mm² cables. These lighting fixtures have relatively low power, and the 16A current-carrying capacity of the 1.5mm² cable is fully capable of meeting the demand. At the same time, its thin wire diameter is convenient for concealed laying in narrow spaces such as inside walls and ceiling interlayers, without affecting the overall aesthetics of the decoration. For example, when laying in the ceiling suspended ceiling, the 1.5mm² cable can easily pass through the keel gaps and connect with the lamp junction box, achieving beautiful and safe wiring.

In addition to lighting circuits, the 1.5mm² cable is also often used as switch control lines. In homes and offices, the connection lines between switches of various lamps and appliances and the equipment usually use 1.5mm² cables. Since the current transmitted in the switch control lines is small, the performance of the 1.5mm² cable is sufficient to meet the requirements, and it has good flexibility, which is convenient for connecting and wiring between the switch panel and the equipment in the wall, reducing construction difficulty.

The 2.5mm² cable is widely used in socket circuits due to its larger current-carrying capacity. In areas such as the living room, bedroom, kitchen, and bathroom of a home, the power supply lines of ordinary wall sockets and multi-functional sockets mostly use 2.5mm² cables. These sockets need to be connected to various appliances, such as living room TVs, stereos, vacuum cleaners, bedroom air conditioners, electric heaters, kitchen refrigerators, microwave ovens, rice cookers, bathroom washing machines, hair dryers, etc. The 25A current-carrying capacity of the 2.5mm² cable can meet the current demand when these appliances work simultaneously.

Especially in areas such as kitchens and bathrooms that need to be connected to high-power appliances, the advantages of the 2.5mm² cable are more obvious. Kitchen appliances such as electric water heaters and microwave ovens have relatively high power, and the current is large when used simultaneously. The 2.5mm² cable can stably transmit power, avoiding safety hazards caused by line overload. The environment in the bathroom is relatively humid, and the insulation layer of the 2.5mm² cable has good moisture resistance, which can work reliably in such an environment, ensuring the safe use of electricity for appliances such as washing machines and electric water heaters.

In the field of small industrial equipment, the 2.5mm² cable can be used as a control line. For example, in small assembly line production, the control lines of sensors, small solenoid valves, relays, and other equipment usually use 2.5mm² cables. These equipment require a small current for control signal transmission but have high requirements for the stability and reliability of the lines. The good performance of the 2.5mm² cable can meet their needs and ensure the normal operation of the equipment.

Both cables support exposed or concealed laying methods. When exposed, they can be directly fixed along walls, ceilings, etc., with convenient installation; when concealed, they can be 穿入 pipes and buried in walls, floors, or ceilings, making the lines more concealed and maintaining a clean and beautiful environment. They are compatible with various installation methods such as pipe threading and wall embedding, and can adapt to different building structures and decoration styles, meeting diversified wiring needs.

In terms of material selection and style design, PVC insulated Single-Core Copper Cables are fully combined with the product's performance requirements and use scenarios, ensuring the high quality and practicality of the cables.

In terms of materials, the conductor is made of high-purity electrolytic copper. Electrolytic copper has undergone refining treatment, with a purity of over 99.9%, and has excellent conductivity, which can ensure the smooth transmission of current and reduce energy loss. High-purity electrolytic copper also has good ductility and toughness. After stranding, it can form a soft and unbreakable conductor structure, making the cable have good flexibility, which is convenient for bending and laying in various complex environments. At the same time, electrolytic copper has good oxidation resistance, is not easily oxidized and corroded during long-term use, can maintain stable conductivity, and extend the service life of the cable.

The insulation layer is made of anti-aging polyvinyl chloride (PVC) material. PVC material has excellent insulation performance, which can effectively block current, prevent short-circuit accidents when the cable is in contact with other conductors, and ensure electrical safety. This material has good temperature resistance, can work stably for a long time in an ambient temperature of -15℃ to 70℃, and can adapt to temperature changes in homes, offices, and small industrial environments. In addition, the PVC Insulation layer also has a certain degree of chemical corrosion resistance, which can resist the erosion of moisture, dust, grease, and other substances in the daily environment, protecting the internal conductor from damage. At the same time, it has good mechanical strength, can withstand a certain degree of external extrusion and friction, and is not easy to be damaged during construction and use.

In terms of style design, the cable has a single-core structure, that is, a stranded Copper Conductor is wrapped with a layer of PVC insulation layer, with a simple and compact structure. This single-core structure makes the cable more flexible in the wiring process, especially when laid through pipes, it can easily pass through pipes with smaller diameters, reducing construction difficulty.

The cable has a variety of appearance colors, commonly including white, black, gray, etc. Different colors are convenient for distinguishing different line functions in circuit wiring. For example, white can be used for live wires and black for neutral wires. This color distinction helps construction personnel accurately identify lines during installation, avoids safety hazards caused by wrong line connection, and improves the standardization and safety of circuit layout.

The surface of the cable is smooth and flat, without burrs, protrusions, or other defects. This design not only makes the cable more beautiful in appearance but also reduces friction resistance with other objects during construction, facilitating pipe threading and laying, and reducing the risk of the insulation layer being scratched. At the same time, the smooth surface is also easy to clean and not easy to accumulate dust and dirt.

Each roll of cable has two specifications of length: 100 meters and 200 meters. The 100-meter specification is suitable for small decoration projects, partial line transformation, and other scenarios, which can reduce material waste; the 200-meter specification is more suitable for large construction projects, large-area wiring, etc., reducing the number of joints, lowering the possibility of faults caused by joint problems, and improving the reliability of the circuit.

The surface of the cable is printed with clear marks, including specification parameters (1.5mm² or 2.5mm²), rated voltage (300/500V), certification marks (such as GB/T 5023.3), manufacturer name, production date, meter scales, etc. These marks are printed with wear-resistant printing technology, which can remain clearly distinguishable during long-term use and construction, facilitating construction personnel to check and operate during cutting and installation, and ensuring the accuracy and efficiency of construction.

The production process of PVC insulated single-core copper cables is rigorous and complex. Each link from raw material processing to finished product inspection undergoes strict quality control to ensure that the products meet relevant standards and requirements.

The first step is the processing of copper materials. High-purity electrolytic copper ingots are selected as raw materials and heated to a molten state, with the temperature controlled at around 1083℃ to completely melt the copper ingots. Then, through a continuous casting process, the molten copper is introduced into a special mold and cooled to form copper rods. During the casting process, parameters such as casting speed and cooling water temperature need to be accurately controlled to ensure that the copper rods have uniform diameter, smooth surface, and dense internal structure, avoiding defects such as pores and cracks. The quality of the copper rods directly affects the performance of subsequent conductors, so this link is crucial.

Next is the wire drawing process of the copper rods. The copper rods are put into a wire drawing machine and drawn through a series of wire drawing dies of different specifications. The aperture of the wire drawing dies gradually decreases, and the copper rods pass through the dies under tension, with the diameter gradually reducing, eventually being drawn into fine copper wires with a diameter of 0.15mm (for 1.5mm² cables) or thicker copper wires (for 2.5mm² cables). During the wire drawing process, the copper wires will have a certain degree of work hardening. To eliminate internal stress and improve the flexibility and ductility of the copper wires, the drawn copper wires need to be annealed. Annealing is carried out in an annealing furnace, where the copper wires are heated to 300-500℃ and kept for a certain time, then slowly cooled to restore the crystal structure of the copper wires to a stable state and improve their performance.

Then is the stranding of copper wires. According to the requirements of cables of different specifications, multiple strands of fine copper wires are stranded by a stranding machine according to a certain stranding pitch to form a conductor with the required cross-sectional area. The design of the stranding pitch should be reasonable. A too small pitch will increase the rigidity of the conductor and affect flexibility; a too large pitch will lead to a loose conductor structure and affect mechanical strength. During the stranding process, it is necessary to ensure that the tension of each strand of copper wire is uniform and arranged neatly to ensure the roundness of the conductor and the uniformity of conductivity. The surface of the Stranded Conductor should be smooth, without burrs, broken wires, or other defects.

After stranding, the insulation layer is extruded. PVC Insulation Material particles are added to the hopper of the extruder, and the material is transported to the heating area through the rotation of the screw. In the extruder, the PVC particles are heated to 160-180℃ and melted into a flowable melt. The molten PVC melt is evenly extruded and wrapped on the surface of the Stranded Copper Conductor through the die of the extrusion head to form an insulation layer. During the extrusion process, it is necessary to accurately control the extrusion temperature, extrusion speed, and die size to ensure that the insulation layer has a uniform thickness (0.8mm for 1.5mm² cables and 0.9mm for 2.5mm² cables), a smooth surface, and is closely combined with the conductor, without defects such as bubbles, impurities, and depressions.

The cable after extrusion of the insulation layer needs to be cooled. Usually, water cooling is adopted, where the cable is introduced into a cooling water tank and rapidly cooled by cold water to quickly solidify and shape the PVC insulation layer, ensuring the dimensional stability and performance stability of the cable. The cooled cable is tested by a spark tester, and a certain high voltage is applied to the surface of the cable to check whether the insulation layer has defects such as pinholes and damage, ensuring that the insulation performance of the insulation layer meets the requirements (insulation resistance ≥100MΩ).

Subsequently, the cable enters the traction and take-up process. The traction machine pulls the cable at a constant speed to ensure uniform tension of the cable and avoid the cable being stretched or damaged due to excessive tension. The take-up machine neatly winds the cable on the reel to form 100-meter or 200-meter coiled products. During the take-up process, it is necessary to control the take-up speed and tension to ensure that the cable is arranged tightly and neatly on the reel, which is convenient for transportation, storage, and use.

During the production process, sampling tests are also required for the cable, including multiple indicators such as the DC resistance of the conductor, the thickness of the insulation layer, voltage resistance performance, insulation resistance, and flexibility. Only cables that meet the requirements of the GB/T 5023.3 standard in all indicators can be delivered as finished products. At the same time, the production workshop must maintain cleanliness to avoid the impact of dust, impurities, etc. on product quality, ensuring that the produced PVC insulated single-core copper cables have stable and reliable performance.

The packaging design of PVC insulated single-core copper cables fully considers the needs of product protection, transportation, storage, and use, ensuring that the cables remain in good condition during circulation.

The cables are packaged in rolls, with each roll having a length of 100 meters or 200 meters. The reels are usually made of hard paper or plastic materials. Paper reels have low cost and good environmental protection, and can be recycled, in line with the concept of green development; plastic reels have better moisture resistance and wear resistance, suitable for storage and transportation in humid environments, and can better protect the cables from moisture.

When the cable is wound on the reel, mechanical automatic winding is adopted. This method can ensure that the cable is arranged neatly and tightly, avoiding mutual extrusion, winding, and wear between cables. During the winding process, by accurately controlling the winding tension, the cable forms a stable roll structure on the reel, preventing loosening during transportation and storage.

After winding, a layer of transparent plastic film is put on the outside of the reel. This layer of plastic film has good sealing performance and can play the role of moisture-proof, dust-proof, and anti-pollution. It can prevent moisture, dust, etc. in the air from entering the surface of the cable, protect the insulation layer from erosion, and also prevent the cable from being damaged by slight collisions and friction from the outside during transportation.

A detailed label is pasted on the side or end face of the reel. The label clearly indicates the product name (PVC insulated single-core copper cable), specification parameters (1.5mm² or 2.5mm²), rated voltage (300/500V), length (100 meters or 200 meters), certification mark (GB/T 5023.3), manufacturer name, production date, batch number, etc. This information is convenient for users to check when duct's performance requirements and usage scenarios, ensuring high quality and practicality of the cable.

In terms of materials, the conductor is made of high-purity electrolytic copper. Electrolytic copper, after refining, has a purity of over 99.9%, which has excellent conductivity, ensuring smooth current transmission and reducing energy loss. High-purity electrolytic copper also has good ductility and toughness. After stranding, it can form a soft and unbreakable conductor structure, making the cable flexible and easy to bend and lay in various complex environments. At the same time, electrolytic copper has good oxidation resistance, which is not easy to be oxidized and corroded during long-term use, and can maintain stable conductivity, prolonging the service life of the cable.

The insulation layer is made of anti-aging polyvinyl chloride (PVC) material. PVC material has excellent insulation performance, which can effectively block current, prevent short-circuit accidents when the cable is in contact with other conductors, and ensure electrical safety. This material has good temperature resistance and can work stably for a long time in an environment with a temperature range of -15℃ to 70℃, adapting to temperature changes in homes, offices, and small industrial environments. In addition, the PVC insulation layer also has a certain degree of chemical corrosion resistance, which can resist the erosion of moisture, dust, grease, and other substances in the daily environment, protecting the internal conductor from damage. At the same time, it has good mechanical strength, can withstand a certain degree of external extrusion and friction, and is not easy to be damaged during construction and use.

This design not only makes the cable more beautiful in appearance but also reduces friction resistance with other objects during construction, facilitating pipe threading and laying, and reducing the risk of damage to the insulation layer. At the same time, the smooth surface is also easy to clean and not easy to accumulate dust and dirt.

Each roll of cable has two specifications: 100 meters and 200 meters. The 100-meter specification is suitable for small decoration projects, partial line transformation, and other scenarios, which can reduce material waste; the 200-meter specification is more suitable for large-scale construction projects, large-area wiring, and other needs, reducing the number of joints, lowering the possibility of faults caused by joint problems, and improving the reliability of the circuit.

The quality of copper rods directly affects the performance of subsequent conductors, so this link is crucial.

Next is the wire drawing process of copper rods. The copper rods are put into a wire drawing machine and drawn through a series of wire drawing dies of different specifications. The aperture of the wire drawing die gradually decreases. Under the action of tension, the copper rod passes through the die, and the diameter gradually becomes smaller. Finally, it is drawn into a fine copper wire with a diameter of 0.15mm (for 1.5mm² cable) or a thicker copper wire (for 2.5mm² cable). During the wire drawing process, the copper wire will produce a certain degree of work hardening. In order to eliminate internal stress and improve the flexibility and ductility of the copper wire, the drawn copper wire needs to be annealed. Annealing is carried out in an annealing furnace. The copper wire is heated to 300-500℃ and kept for a certain time, then slowly cooled to restore the crystal structure of the copper wire to a stable state and improve its performance.

Then is the stranding of copper wires. According to the requirements of cables of different specifications, multiple strands of fine copper wires are stranded by a stranding machine according to a certain stranding pitch to form a conductor with the required cross-sectional area. The design of the stranding pitch should be reasonable. If the pitch is too small, it will increase the rigidity of the conductor and affect flexibility; if the pitch is too large, it will lead to loose conductor structure and affect mechanical strength. During the stranding process, it is necessary to ensure that the tension of each strand of copper wire is uniform and arranged neatly to ensure the roundness of the conductor and the uniformity of conductive performance. The surface of the stranded conductor should be smooth, without burrs, broken wires, and other defects.

After stranding, the insulation layer is extruded. PVC Insulation Material particles are added into the hopper of the extruder, and the material is transported to the heating area through the rotation of the screw. In the extruder, PVC particles are heated to 160-180℃ and melted into a flowable melt. The molten PVC melt is evenly extruded and wrapped on the surface of the stranded copper conductor through the die of the extrusion head to form an insulation layer. During the extrusion process, it is necessary to accurately control the extrusion temperature, extrusion speed, and die size to ensure that the insulation layer has a uniform thickness (0.8mm for 1.5mm² cable and 0.9mm for 2.5mm² cable), a smooth surface, and is closely combined with the conductor, without defects such as bubbles, impurities, and depressions.

The cable after extrusion of the insulation layer needs to be cooled. Usually, water cooling is adopted. The cable is introduced into a cooling water tank and rapidly cooled by cold water, so that the PVC insulation layer is quickly solidified and shaped to ensure the dimensional stability and performance stability of the cable. The cooled cable is tested by a spark tester. A certain high voltage is applied to the surface of the cable to check whether the insulation layer has defects such as pinholes and damage, ensuring that the insulation performance of the insulation layer meets the requirements (insulation resistance ≥100MΩ).

Subsequently, the cable enters the traction and take-up process. The traction machine pulls the cable at a constant speed to ensure uniform tension of the cable and avoid the cable being stretched or damaged due to excessive tension. The take-up machine neatly winds the cable on the reel to form 100-meter or 200-meter coiled products. During the take-up process, it is necessary to control the take-up speed and tension to ensure that the cable is arranged tightly and neatly on the reel, which is convenient for transportation, storage, and use.

During the production process, sampling tests are also required for the cable, including multiple indicators such as DC resistance of the conductor, thickness of the insulation layer, voltage resistance performance, insulation resistance, and flexibility. Only cables that meet the requirements of GB/T 5023.3 standard in all indicators can be delivered as finished products. At the same time, the production workshop must maintain cleanliness to avoid the impact of dust, impurities, etc. on product quality, ensuring that the produced PVC insulated single-core copper cable has stable and reliable performance.

The packaging design of PVC insulated single-core copper cable fully considers the needs of product protection, transportation, storage, and use, ensuring that the cable remains in good condition during circulation.

The cable is packaged in rolls, with each roll length of 100 meters or 200 meters. The reels are usually made of hard paper or plastic materials. Paper reels have low cost and good environmental protection, and can be recycled, in line with the concept of green development; plastic reels have better moisture resistance and wear resistance, suitable for storage and transportation in humid environments, and can better protect the cable from moisture.

When the cable is wound on the reel, mechanical automatic winding is adopted. This method can ensure that the cable is arranged neatly and tightly, avoiding mutual extrusion, winding, and wear of the cable. During the winding process, by accurately controlling the winding tension, the cable forms a stable coiled structure on the reel, preventing loosening during transportation and storage.

After winding, a layer of transparent plastic film is wrapped around the outside of the reel. This layer of plastic film has good sealing performance and can play the role of moisture-proof, dust-proof, and anti-pollution. It can prevent moisture, dust, etc. in the air from entering the surface of the cable, protect the insulation layer from erosion, and also prevent the cable from being damaged by slight collision and friction from the outside during handling.

A detailed label is pasted on the side or end face of the reel. The label clearly indicates the product name (PVC insulated single-core copper cable), specification parameters (1.5mm² or 2.5mm²), rated voltage (300/500V), length (100 meters or 200 meters), certification mark (GB/T 5023.3), manufacturer name, production date, batch number, etc. This information is convenient for users to check when receiving and accepting products, ensuring that the received products are consistent with the order requirements, and also provides a basis for product quality traceability.

For cables transported in batches, multiple reels are neatly stacked on wooden pallets or sturdy cartons. Wooden pallets have strong bearing capacity, which is convenient for loading, unloading, and handling with forklifts and other equipment, improving transportation efficiency, and are suitable for long-distance transportation of large quantities of products; cartons are suitable for transportation of small quantities of products, with light weight, easy manual handling and stacking, and low cost. During stacking, partitions or buffer materials (such as foam boards, bubble films, etc.) are placed between the reels to reduce mutual collision and friction, further protecting the products from damage.

The selection of packaging materials focuses on environmental protection and recyclability, trying to reduce environmental pollution. Packaging materials such as paper reels and cartons can be recycled and reused, and plastic films are also made of degradable or recyclable materials, in line with the requirements of modern society for environmentally friendly packaging. At the same time, under the premise of ensuring product safety, excessive packaging is avoided, packaging materials are saved, and packaging costs are reduced.

The transportation process of PVC insulated single-core copper cable needs to strictly abide by relevant regulations and operating procedures to ensure that the products are delivered to the destination safely and timely.

The choice of transportation mode depends on the transportation distance, quantity, and customer needs. Short-distance transportation (such as within a city or surrounding areas) usually adopts road transportation. Road transportation has the characteristics of high flexibility, fast transportation speed, and door-to-door service, which can quickly deliver products to customers, and is suitable for transportation of small batches and urgent orders. For long-distance transportation (such as across provinces and cities), railway transportation can be chosen. Railway transportation has the advantages of large transportation capacity, low cost, and little impact from weather, which is suitable for transportation of large quantities of products and can ensure the stability and economy of the transportation process. For export products or orders with special requirements, sea or air transportation can also be used. Sea transportation is suitable for transportation of large quantities of non-urgent goods with low cost; air transportation is fast and suitable for urgent orders, but the cost is relatively high.

Before transportation, the packaged cables need to be properly fixed. For cables packaged in a single reel, when loading into transport vehicles or containers, they should be placed stably, and fixed in the carriage with ropes, strapping, etc. to prevent the reels from shaking, tipping over, or colliding with each other due to vehicle bumps and turns during transportation. For cables stacked on wooden pallets, the pallets and reels should be tightly wrapped together with stretch film to enhance the overall stability and avoid scattering during transportation.

During transportation, effective protective measures should be taken to prevent the cables from direct sunlight, rain, snow, and high-temperature exposure. Direct sunlight and high-temperature exposure will cause the cable temperature to rise, which may cause aging and softening of the PVC insulation layer, affecting its insulation performance and mechanical strength; rain and snow will make the cable damp, reducing the insulation resistance, affecting the electrical performance of the cable, and even causing mold growth on the surface of the insulation layer, affecting the service life. Therefore, during transportation, transport vehicles or containers should be covered with tarpaulins to protect the cables from harsh weather.

In addition, during transportation, it is necessary to avoid mixing the cables with sharp objects, corrosive substances, and flammable and explosive materials. Sharp objects may scratch the insulation layer of the cable, resulting in insulation damage; corrosive substances may corrode the insulation layer and conductor, affecting the performance of the cable; flammable and explosive materials may bring safety hazards such as fire and explosion, threatening the safety of the cable and transportation.

The driver should drive steadily during transportation, avoid sudden braking, sharp turns, and overspeeding, and reduce the impact and vibration on the cables. For long-distance transportation, regular inspections should be carried out during the transportation process to check whether the fixing of the cables is loose, whether the packaging is damaged, and whether the cables are damp or contaminated. If problems are found, timely measures should be taken to deal with them, such as re-fixing the loose cables, replacing the damaged packaging, etc., to ensure that the cables are in good condition during transportation.

When loading and unloading, appropriate loading and unloading equipment and tools should be used, such as forklifts, cranes, etc., to avoid manual handling of heavy reels. Manual handling is not only easy to cause damage to the cables but also may lead to personal injury. During loading and unloading, it is necessary to operate gently, avoid collision between the reels and the equipment or between the reels, and place the reels stably in the transport vehicle or storage area to prevent them from tipping over or falling.

The shipping process of PVC insulated single-core copper cable is efficient and standardized, aiming to ensure that the products are delivered to customers accurately and on time.

After receiving the customer's order, the sales department will promptly sort out and verify the order information, including product specifications (1.5mm² or 2.5mm²), quantity, delivery address, contact person, and contact information. After confirming that the order information is correct, it will be transmitted to the warehouse department for processing.

The warehouse staff will first check the inventory according to the order requirements. If there is sufficient stock, they will start the shipping preparation work within 24 hours, including product inspection, packaging reinforcement, etc. If the stock is insufficient, the warehouse department will communicate with the production department in a timely manner to arrange production. The production department will formulate a production plan based on the order quantity and delivery time, ensuring that the products are produced on time and delivered to the warehouse.

Before shipping, the warehouse staff will conduct a comprehensive inspection of the cables to be shipped. They will check whether the product specifications, quantities, and packaging are consistent with the order requirements. They will also inspect the appearance of the cables, such as whether the insulation layer is intact, whether there are scratches, cracks, or color differences, and whether the marks on the surface are clear. For some key performance indicators, such as insulation resistance, spot checks will be carried out to ensure that the products meet the quality standards.

After passing the inspection, the cables will be packed and labeled. According to the transportation mode and distance, the packaging will be reinforced. For example, for long-distance transportation, the reels will be wrapped with more layers of plastic film or placed in stronger cartons to prevent damage during transportation. The shipping label will clearly indicate the customer's information, product information, shipping address, and contact information to facilitate the logistics company's identification and delivery.

The warehouse department will choose a suitable logistics company according to the customer's requirements and the actual situation. For domestic shipments, common logistics methods include road transportation, railway transportation, and express delivery. The warehouse staff will coordinate with the logistics company to arrange the pickup time and ensure that the goods are loaded and shipped in a timely manner.

Once the goods are shipped, the sales department will promptly inform the customer of the shipping information, including the logistics company name, waybill number, estimated delivery time, and the logistics company's contact information. This allows customers to track the transportation status of the goods in real-time through the logistics company's official website or customer service, and make relevant receiving preparations.

For international shipments, in addition to the above steps, the warehouse department also needs to handle export customs declaration procedures.
