Structure and Process: It adopts a 4-core 95 square millimeter Aluminum Conductor structure, made through the compact stranding process. The compact stranding process greatly improves the filling density of the conductor, reduces the gaps inside the conductor, not only reduces the skin effect loss during current transmission but also enhances the Flexibility of the cable, making it easier to lay in complex environments.

DC Resistance: At 20℃, the DC resistance of a single-core conductor is ≤0.32Ω/km. The low DC resistance means less energy loss during power transmission, enabling efficient transmission of power to lighting equipment and meeting the power demand of high-power lighting equipment.

Conductor Diameter: A single-core conductor is stranded by multiple Aluminum Wires, with a single Aluminum Wire diameter of about 2.0mm. The diameter of the stranded single-core conductor is about 10mm. The overall diameter of the 4-core Stranded Conductor, combined with the insulation layer and outer sheath, can adapt to different laying environments.

Material: The insulation layer is made of special materials that meet the Nayy Na2xy standard. This material has been specially developed with excellent electrical insulation performance and weather resistance, which is the key to ensuring the insulation effect of the cable.

Volume Resistivity: The volume resistivity is ≥1×10¹³Ω·cm. The high volume resistivity indicates that it has excellent insulation performance, which can effectively prevent current leakage and ensure safety during power transmission.

Insulation Strength: The insulation strength is ≥18kV/mm, with strong resistance to electrical breakdown. It can maintain a stable insulation state under normal working voltage and possible instantaneous voltage fluctuations, avoiding insulation failures.

Operating Temperature Range: It can work stably in the ambient temperature range of -40℃ to 70℃. Whether in cold northern winters or hot southern summers, it can adapt to changes in ambient temperature, ensuring the normal power supply of the lighting system.

Thickness: The insulation layer has a uniform thickness. The insulation layer thickness of a single-core conductor is about 1.8mm. The uniform thickness can ensure the consistency of insulation performance and avoid potential safety hazards caused by local thin insulation.

Impulse Voltage Withstand Capacity: To achieve the lightning protection function, the cable has been specially optimized in structural design, with a certain ability to withstand impulse voltage. It can withstand the instantaneous high-voltage impact generated during lightning strikes. Tests show that its impulse voltage withstand value can reach more than 10kV, which can effectively reduce the damage of lightning to connected lighting equipment.

Lightning Protection Structure Design: The cable is equipped with a special lightning protection shielding layer inside, made of high-conductivity materials, which can quickly introduce the current generated by lightning into the ground, avoiding damage to lighting equipment caused by current passing through them. The thickness of the shielding layer is about 0.5mm, tightly wrapped around the outer side of the insulation layer to ensure the reliability of the lightning protection effect.

Material: The outer sheath is made of aging-resistant and UV-resistant materials, which can adapt to complex outdoor environmental conditions and prolong the service life of the cable.

Thickness: The thickness is uniform and ≥2.0mm. Sufficient thickness can provide effective protection for the internal structure of the cable, resisting external mechanical damage.

Mechanical Properties: The tensile strength is ≥10MPa, and the elongation at break is ≥120%, with good toughness and strength. It is not easy to break during laying and use, and can withstand a certain degree of stretching and bending.

Corrosion Resistance: It has good corrosion resistance, can resist the erosion of acid-base substances in the air, rainwater, etc., and ensure normal operation in humid, dusty and other environments.

Laid in air: The current-carrying capacity is about 210A. In this laying mode, the cable has good heat dissipation conditions and can pass a large current, meeting the demand of multiple groups of high-power lamps in large lighting systems to operate simultaneously.

Laid underground: The current-carrying capacity is about 170A. The heat dissipation in the underground environment is relatively poor, but the cable can still maintain a high current-carrying capacity, suitable for scenarios such as street lamp systems that need to be laid underground.

Raw Material Selection: High-purity aluminum ingots with a purity of ≥99.5% are selected. Strict inspections are carried out on aluminum ingots, including chemical composition analysis and mechanical property testing, to ensure that the quality of raw materials meets the requirements, and only qualified aluminum ingots can enter the next production step.

Wire Drawing: The aluminum ingot is drawn into single wires with a diameter of about 2.0mm through a wire drawing machine. During the wire drawing process, the wire drawing speed, die size and cooling system are controlled to ensure that the diameter of the single wire is uniform, the surface is smooth, and there are no scratches, cracks and other defects. The drawn single wire needs to be cleaned and dried to remove oil and impurities on the surface.

Compact Stranding: Multiple single wires are stranded through a compact stranding machine according to a certain number and stranding pitch to form a 95 square millimeter single-core conductor. During the stranding process, the stranding pressure and speed are precisely controlled to make the conductor structure compact with high filling density, reducing the impact of the skin effect. At the same time, ensure that the stranded single-core conductor has good roundness and high consistency. When 4-core conductors are stranded, they are arranged in a specific way to ensure the stability of the overall structure.

Annealing Treatment: The stranded conductor is annealed, heated to about 300-350℃, kept warm for a period of time, and then slowly cooled to eliminate internal stress in the conductor and improve the flexibility and conductivity of the conductor. The annealed conductor needs to be surface-treated to remove the oxide layer and ensure the quality of the conductor.

Material Preparation: Special Insulation Materials that meet the Nayy Na2xy standard are selected, and strict inspections are carried out on the materials, including appearance, electrical properties, weather resistance, etc. Before extrusion, the insulation material is dried to remove moisture in the material to avoid bubbles in the insulation layer.

Extrusion Molding: An extruder is used to extrude and coat the insulation material on the outer layer of the single-core conductor to form an insulation layer. According to the specifications of the conductor, the parameters of the extruder, such as temperature (about 120-140℃), speed and pressure, are adjusted to ensure that the thickness of the insulation layer is uniform, about 1.8mm, meeting the design requirements. During the extrusion process, the quality of the insulation layer is monitored in real-time, and parameters such as the thickness and eccentricity of the insulation layer are detected by online testing equipment to ensure that the surface is smooth and free of bubbles, cracks and other defects.

Material Selection: High-conductivity materials such as copper tape or tinned Copper Wire are selected as lightning protection shielding layer materials. The conductivity and thickness of the materials are strictly inspected to ensure that they can conduct lightning current quickly.

Shielding Layer Wrapping: The lightning protection shielding layer material is tightly wrapped around the outer side of the insulation layer. For copper Tape Shielding, the wrapping method is adopted, and the wrapping tension and overlap are controlled to ensure the continuity and tightness of the shielding layer; for tinned copper wire shielding, the braiding method is adopted to ensure the braiding density and shielding effect. The thickness of the shielding layer is about 0.5mm, evenly wrapped around the outer side of each Insulated Wire core.

Material Preparation: Aging-resistant and UV-resistant materials are selected as outer sheath materials, and inspections are carried out on the materials, including appearance, mechanical properties, weather resistance, etc. Before extrusion, the material is mixed and plasticized to ensure the uniformity and performance stability of the material.

Extrusion Molding: After stranding the 4 Cores wrapped with insulation layer and shielding layer together, an extruder is used to extrude and coat the outer sheath material on its outer layer to form an outer sheath. The parameters of the extruder, such as temperature (about 150-170℃), speed and pressure, are adjusted to ensure that the thickness of the sheath is uniform and ≥2.0mm, closely combined with the internal structure, with a smooth surface and no bubbles, cracks and other defects. During the extrusion process, the quality of the sheath is monitored in real-time, and its thickness, outer diameter and other parameters are detected.

Raw Material Inspection: Strict inspections are carried out on aluminum ingots, insulation materials, lightning protection shielding layer materials, outer sheath materials and other raw materials. Only qualified raw materials can enter the production process.

In-Process Inspection: Quality control points are set in each production link such as conductor manufacturing, insulation layer extrusion, lightning protection shielding layer production, and outer sheath extrusion to inspect semi-finished products. For example, inspect the diameter and DC resistance of the conductor, the thickness and eccentricity of the insulation layer, the continuity and tightness of the shielding layer, the thickness and mechanical properties of the sheath, etc., to ensure that the product quality of each link meets the requirements.

Finished Product Inspection: Finished cables need to pass a number of strict tests, including power frequency withstand voltage test (3kV/5min without breakdown), insulation resistance test, impulse voltage withstand test, current-carrying capacity test, mechanical performance test (such as tensile strength, elongation at break), weather resistance test, etc. A certain number of samples are taken from each batch of products for comprehensive testing, and only products with all indicators qualified can leave the factory.

Quality Traceability: A sound quality traceability system is established to record information such as the source of raw materials, parameters during production, and test results, and establish quality files for each batch of products. If quality problems occur during use, they can be traced back to the production link in a timely manner, the causes can be found, and improvement measures can be taken to continuously improve product quality.

Cable Reels: Cables are usually wound on sturdy steel cable reels. Steel cable reels have high strength and high load-bearing capacity, which can bear the weight of the cable and the impact force during transportation. The diameter and width of the cable reel are determined according to

Protective Materials: The outer layer of the cable is wrapped with a moisture-proof and wear-resistant plastic film. The plastic film has good moisture-proof performance, which can prevent the cable from getting damp during transportation and storage; at the same time, it can also play a certain anti-wear role, protecting the outer sheath of the cable from scratches. For cables exported or transported over long distances, a layer of linen or woven bag is wrapped around the outer layer of the plastic film to further enhance the firmness and protective performance of the packaging.

Winding and Fixing: The cable is neatly wound on the cable reel, and the tension is controlled during the winding process to avoid loose or excessive stretching of the cable. Special fixing devices are used at both ends of the cable to fix it to prevent the cable from slipping off the cable reel during transportation.

Marking Information: Relevant product information is clearly marked on the side and end of the cable reel, including product name, model specification (Nayy Na2xy 4c*95 Sqr. mm), rated voltage (1kv), AC voltage (240V), length, weight, production batch number, implementation standard, production date, manufacturer name, address and contact information, etc. These marking information are convenient for customers to quickly identify the product when receiving and inspecting the goods, and also facilitate product traceability and management.

Road Transportation: Choose trucks in good condition for transportation. Before transportation, the cable reels are firmly fixed in the carriage, using steel wire ropes or chains for binding to prevent the cable reels from rolling, tilting or colliding during transportation. Buffer materials such as rubber pads and wooden boards are placed between the cable reels to avoid mutual friction and collision. During transportation, drivers should abide by traffic rules, avoid violent operations such as sudden braking and sharp turns, and reduce the impact on the cables. During long-distance transportation, stop regularly to check the fixing of the cable reels and handle problems in a timely manner if found.

Railway Transportation: When transporting by railway, comply with the relevant regulations of railway transportation. The cable reels are loaded into railway carriages in an orderly manner and fixed firmly to prevent movement during transportation. The loading and unloading process should be gentle to avoid damage to the cable reels and cables caused by rough operation.

Sea Transportation: For sea transportation, especially for exported cables, the packaging should be strengthened. The cable reels are wrapped with waterproof and moisture-proof materials to prevent the cables from getting damp due to seawater erosion or high humidity during transportation. At the same time, the cable reels are fixed in the container to prevent them from colliding with each other due to ship shaking.

Storage Environment: The cable should be stored in a dry, ventilated, and clean warehouse, away from direct sunlight, rain, and snow. The warehouse should be kept at a temperature between -5℃ and 35℃ and a relative humidity not exceeding 75% to avoid the cable being affected by extreme temperatures and humidity. The warehouse should be free from corrosive gases, vapors, and dust to prevent corrosion and pollution of the cable.

Placement Method: The cable reels should be placed horizontally on a flat ground, and supports can be placed under the cable reels to prevent them from getting damp. The cable reels should not be stacked too high to avoid crushing the lower cable reels. There should be a certain distance between the cable reels to facilitate ventilation and inspection.

Storage Time: The storage time of the cable should be controlled as much as possible. Generally, the maximum storage time should not exceed 2 years. During storage, regular inspections should be carried out, including checking the appearance of the cable, the tightness of the packaging, and the moisture-proof condition, etc. If any problems are found, such as sheath aging, moisture, etc., timely measures should be taken for treatment.
