Conductor Material: This series of cables all use high - purity copper as the conductor. High - purity copper has excellent electrical conductivity. Its high conductivity can minimize energy loss during power transmission and improve power transmission efficiency. At the same time, pure copper has good ductility and Flexibility, making the cable easier to bend and lay during installation and use, and adapting to different installation environments.

Insulation layer material: The insulation layer of the cable is made of polyvinyl chloride (PVC) material. PVC material has good insulation performance, which can effectively block current, prevent electric leakage, and ensure electrical safety. It also has excellent corrosion resistance, which can resist the erosion of acids, alkalis, salts and other chemical substances, and prolong the service life of the cable. In addition, PVC material has certain mechanical strength, which can withstand certain external impact and extrusion, and protect the internal conductor from damage.

Style design: The cable as a whole presents a cylindrical appearance with a smooth and flat surface. Cables of different specifications differ in diameter. Large - specification cables have a larger diameter, while small - specification ones are relatively thinner, which also makes them easy to distinguish in appearance. The color of the cable is usually dark colors such as black or gray. This color choice is not only resistant to dirt, but also can resist ultraviolet radiation to a certain extent, reducing aging caused by direct sunlight.

Conductor processing: First, high - purity copper is smelted and cast to form copper rods. Then, the copper rod is drawn into Copper Wires of different diameters through the wire drawing process, and these copper wires will be used as the conductors of the cable. During the wire drawing process, it is necessary to strictly control the drawing speed and temperature to ensure the stable quality and performance of the copper wire. Then, multiple copper wires are stranded to form a conductor core. The stranding process can improve the flexibility and mechanical strength of the conductor.

Insulation layer extrusion: The extrusion molding process is used to wrap the PVC Insulation layer outside the conductor core. During the extrusion process, after the PVC material is heated and melted, it is evenly wrapped on the conductor core through the die of the extruder to form a continuous insulation layer. It is necessary to accurately control the extrusion temperature, speed and pressure to ensure that the thickness of the insulation layer is uniform, the surface is smooth, and it is closely combined with the conductor core without defects such as bubbles and impurities.

Cabling process: For multi - Core Cables, it is necessary to strand multiple Insulated Cores according to a certain stranding method. During the cabling process, it is necessary to ensure that the positions of each core are accurate and the stranding is tight. At the same time, appropriate fillers are filled during the stranding process to improve the roundness and stability of the cable.

Sheath extrusion (if needed): Some cables may also need to extrude a sheath after cabling to further enhance the protection performance of the cable. The sheath material can also be PVC or other suitable materials, and the extrusion process is similar to that of the insulation layer.

Quality inspection: Strict quality inspection procedures are set up in each link of the production process. The diameter and resistivity of the conductor are tested to ensure that they meet relevant standards; the thickness, insulation resistance, voltage resistance and other properties of the insulation layer are tested to ensure the insulation effect; the appearance, mechanical performance and electrical performance of the cabled cable are inspected to ensure that each batch of cables can meet the quality requirements.

Packaging materials: Cables are usually packaged with wooden shafts or cable reels. The wooden shaft is made of high - quality solid wood materials, which has strong bearing capacity and stability, and can bear the weight of the cable and the external force generated during transportation. The side of the cable reel is usually equipped with a metal flange to enhance its structural strength.

Packaging method: The cable is neatly wound on the wooden shaft or cable reel. During the winding process, it is necessary to ensure that the cable is arranged tightly without distortion and cross. A layer of plastic film is wrapped around the outer layer of the cable to prevent the cable from being polluted by dust, moisture, etc. For some small - specification cables, they can also be packaged in rolls. The length of each roll is determined according to actual needs, usually 100 meters or 200 meters.

Packaging marks: The model, specification, length, production date, batch number, implementation standard and other information of the product are clearly marked on the package, and the name, address, contact information of the manufacturer are also marked. These marks help users identify and confirm product information, and also facilitate product traceability and management.

Transportation mode: Select the appropriate transportation mode according to the order quantity, destination and customer requirements. For large quantities of cables, road transportation or railway transportation is usually used. Road transportation has the characteristics of high flexibility and door - to - door service, which is suitable for short - distance and medium - short - distance transportation; railway transportation is suitable for long - distance transportation, with the advantages of large transportation volume and relatively low cost. For some urgent orders or small batches of samples, air transportation can also be used to shorten the transportation time.

Transportation precautions: During transportation, ensure that the cable package is intact to avoid collision, extrusion, rain and exposure to the sun. When loading cables, place them stably to avoid tilting and inversion, and prevent the cable reel from rolling and causing damage. The transport vehicle should drive smoothly to reduce 颠簸. For long - distance transportation, regularly check the condition of the cable to ensure its safety.

Transportation insurance: In order to reduce the risk during transportation, the company can handle transportation insurance for customers. The insurance premium is determined according to the value of the goods and the mode of transportation. In case of damage or loss of goods during transportation, the insurance company will compensate according to relevant regulations.

Delivery time: After receiving the customer's order and confirming the payment, the company will arrange production and delivery as soon as possible. For products in stock, they are usually delivered within 1 - 3 working days; for customized products, the delivery time will be determined according to the production cycle, generally 7 - 15 working days, and the specific time will be communicated with the customer in advance.

Delivery process: First, warehouse personnel accurately pick the products according to the order information and check them to ensure that the model, specification, quantity of the products are consistent with the order. Then, the products are packaged and reinforced to ensure safety during transportation. Next, contact the logistics company, arrange the transport vehicle, and timely inform the customer of the delivery information, including the name of the logistics company, waybill number, etc., to facilitate the customer to query the transportation status of the goods.

Delivery tracking: The company will track the transportation process of the goods and timely understand the position and status of the goods. If there is any abnormal situation during transportation, it will communicate with the logistics company in a timely manner to solve it and inform the customer as soon as possible.
