Conductor material: All cables use aluminum as the core conductor. The selected aluminum has high purity, which ensures its good electrical conductivity. Aluminum itself is light in weight. Compared with Copper Conductors, it can reduce the overall weight of the cable and reduce the burden during installation. At the same time, the cost of aluminum is relatively low, making the cable more competitive in price. Moreover, aluminum has certain corrosion resistance and can maintain good performance in general environments.

Insulation layer material: The 50mm single - core aluminum cable uses polyvinyl chloride (PVC) as the insulation layer. This material has good insulation performance, wear resistance and processing performance, and the price is relatively low. The insulation layers of 300mm, 600mm² single - core Aluminum Cables and Nayy - O 1×400mm² power cables mostly use cross - linked polyethylene (XLPE). XLPE has excellent electrical performance, heat resistance and mechanical strength, can work stably at high temperatures for a long time, and has good chemical corrosion resistance, so it can adapt to more complex environments.

Style design: All cables are of single - core design, which makes them highly flexible in wiring and able to adapt to different installation environments. The single - core structure also makes it more convenient for the cable to bend and pass through pipes, reducing the difficulty in the installation process. At the same time, the single - core design is conducive to heat dissipation, which can improve the current - carrying capacity and service life of the cable. The appearance of the cable is usually round with a smooth surface, which is easy to lay and maintain.

Conductor manufacturing: First, the aluminum raw materials are smelted and purified to remove impurities and improve the purity of aluminum. Then, the aluminum ingots are processed into Aluminum Conductors with the required cross - sectional specifications through a continuous extrusion process. During the extrusion process, the temperature and pressure are strictly controlled to ensure the dimensional accuracy and mechanical properties of the conductor. After that, the conductor is annealed to eliminate internal stress and improve its flexibility and electrical conductivity.

Insulation layer extrusion: The extrusion molding process is used to wrap the insulation layer around the conductor. Corresponding extrusion temperature, speed and other parameters are set according to different Insulation Materials. During the extrusion process, it is ensured that the insulation layer is evenly wrapped on the surface of the conductor without defects such as bubbles and impurities. For the XLPE insulation layer, cross - linking treatment is also required. By heating, the XLPE molecules form a cross - linked structure, thereby improving its heat resistance and mechanical properties.

Cooling and solidification: The cable with the extruded insulation layer enters the cooling water tank for cooling to make the insulation layer solidify and form quickly. During the cooling process, the water temperature and cooling speed are controlled to ensure the stable performance of the insulation layer.

Inspection and packaging: The finished cables need to undergo a series of inspections, including conductor resistance test, insulation resistance test, and withstand voltage test, to ensure that the performance of the cables meets relevant standards. The qualified cables after inspection are packed in reels or coils for storage and transportation.

Packaging materials: Cables are usually packaged with cable reels, which are divided into wooden and steel types. Wooden cable reels have low cost and light weight, but their load - bearing capacity is relatively weak, and they are suitable for packaging small - section and short - length cables. Steel cable reels have strong load - bearing capacity and high strength, and are suitable for packaging large - section and long - length cables, which can better protect the cables from damage during transportation and storage. For short - length cables, plastic reels or cartons can also be used for packaging.

Packaging methods: The cable is neatly wound on the cable reel, and a certain tension is maintained during the winding process to avoid the cable from loosening. A layer of moisture - proof film is wrapped around the outer layer of the cable to prevent it from getting damp. For wooden cable reels, protective plates are installed on the edges and sides of the reels to prevent the cables from being hit. The specifications, model, length, production date, brand and other information of the cable are marked on the cable reel for easy identification and traceability.

Packaging requirements: The packaging should be firm and reliable, able to withstand bumps and collisions during transportation, and prevent the cable from moving and wearing in the package. At the same time, the packaging should have good moisture - proof and dust - proof performance to protect the cable from the influence of the external environment. For exported cables, the packaging must also meet the packaging standards and requirements of relevant countries.

Transportation methods: Select appropriate transportation methods according to factors such as the quantity, specifications and transportation distance of the cables. Truck transportation can be used for short - distance transportation, and railway transportation or sea transportation can be chosen for large - quantity and long - distance transportation. During transportation, ensure that the cables are placed stably to avoid tilting and inversion.

Transportation precautions: During transportation, prevent the cables from being squeezed, collided, exposed to the sun and rain. A certain gap should be left between the cable reels to avoid mutual friction. For steel cable reels, steel wire ropes can be used to fix them on the transport vehicle to prevent movement during transportation. When loading and unloading cables, special hoisting equipment should be used to avoid damage to the cables and cable reels. During transportation, drivers should drive carefully and avoid sudden braking and sharp turns.

Transportation marks: Marks such as "Handle with Care", "Moisture - proof" and "No Rolling" are marked in obvious positions of the transport vehicle to remind transport personnel to pay attention. At the same time, the relevant information of the cable is indicated on the transportation documents for checking and management during transportation.

Delivery process: After receiving the customer's order, warehouse personnel check the specifications, model and quantity of the cable according to the order information to ensure that the goods are accurate. Then arrange for the goods to be delivered from the warehouse, and carry out packaging and marking. Contact the transportation company to determine the transportation method and time, and hand over the goods to the transportation company. At the same time, inform the customer of the delivery information, such as the transportation order number and the estimated arrival time, to facilitate the customer to track the logistics information of the goods.

Delivery time: When there is sufficient inventory, delivery is generally arranged within 1 - 3 working days after receiving the order. For cables with customized specifications, the delivery time is determined according to the production cycle, and timely communication with the customer is carried out.

Delivery tracking: Maintain close contact with the transportation company to track the transportation status of the goods. In case of transportation delays, goods damage and other situations, communicate with the customer in a timely manner and take corresponding solutions.
