Conductor Material: The core conductor of the cable is made of high-purity copper. High-purity copper has excellent electrical conductivity, low resistivity, which can reduce energy loss during current transmission and improve power transmission efficiency. This is crucial for equipment that needs to run continuously such as machine tools, which can reduce energy consumption and save production costs. At the same time, high-purity copper has good ductility and Flexibility, which is convenient for cable processing and installation. During wiring, it can be bent and folded as needed without breaking easily.

Insulation layer material: The insulation layer complies with THHN/THWN standards and integrates the dual characteristics of thermoplastic high heat-resistant nylon (THHN) and thermoplastic moisture-resistant nylon (THWN). This material has excellent insulation performance, which can effectively isolate current and prevent electric leakage accidents. The thermoplastic material makes the insulation layer plastic within a certain temperature range, which is convenient for cable processing and forming, and can maintain stable shape and performance at normal working temperature. The High Heat Resistance ensures that the insulation layer will not melt or deform in high-temperature environments, and the moisture resistance can prevent water from entering the insulation layer and affecting the insulation effect.

Shell material: The outer layer of the cable is wrapped with a tough nylon shell. Nylon is an excellent engineering plastic with high mechanical strength, excellent wear resistance and tear resistance. During the operation of the machine tool, the cable may rub and collide with other equipment and the ground. The nylon shell can effectively protect the internal conductor and insulation layer and reduce physical damage. In addition, nylon material also has good chemical corrosion resistance and weather resistance, which can adapt to different industrial environments and extend the service life of the cable.

Conductor manufacturing: First, high-purity copper raw materials are selected and made into copper rods through smelting, casting and other processes. The copper rod is drawn into Copper Wires meeting the specifications of 8 AWG, 1/0 AWG and 3/0 AWG through wire drawing process. During the wire drawing process, the size of the wire drawing die and the wire drawing speed are precisely controlled to ensure that the diameter of the copper wire is uniform and the surface is smooth, so as to ensure the electrical conductivity and mechanical properties of the conductor. The drawn copper wire needs to be annealed. The annealing process can eliminate the internal stress generated during the wire drawing process, improve the flexibility and ductility of the copper wire, and facilitate the subsequent stranding process.

Conductor stranding: For larger conductors, such as 1/0 AWG and 3/0 AWG, multiple copper wires need to be stranded together to form a conductor. During the stranding process, the stranding pitch and direction are precisely controlled to ensure that the conductor structure is tight and round, and improve the mechanical strength and electrical conductivity of the conductor. The surface of the Stranded Conductor needs to be cleaned to remove oil, impurities, etc. on the surface to ensure good bonding with the insulation layer.

Insulation layer extrusion: The insulation layer is wrapped around the conductor by extrusion molding process. The Insulation Material meeting THHN/THWN standards is heated and melted, and then extruded onto the conductor surface through the die of the extruder to form a uniform and continuous insulation layer. During the extrusion process, the extrusion temperature, speed and pressure are precisely controlled to ensure that the insulation layer has uniform thickness, smooth surface, close bonding with the conductor, and no defects such as bubbles and impurities. The thickness of the insulation layer is strictly designed according to the rated voltage and service environment of the cable to meet the requirements of insulation performance.

Shell wrapping: A nylon shell is wrapped around the insulation layer. The same extrusion molding process is used. The nylon material is heated and melted and then extruded onto the surface of the insulation layer to form a tough shell. During the shell extrusion process, the extrusion parameters need to be precisely controlled to ensure that the shell has uniform thickness, smooth surface and close bonding with the insulation layer. The thickness of the shell is designed according to the service environment and mechanical strength requirements of the cable to provide effective protection.

Inspection and testing: The finished cable needs to undergo strict inspection and testing. Including appearance inspection to check whether the cable surface has scratches, damage, bubbles and other defects; size inspection to measure the outer diameter of the cable, conductor diameter, insulation layer thickness, shell thickness and other parameters to ensure compliance with design requirements; electrical performance testing to test the insulation resistance and voltage resistance of the cable to ensure that its electrical performance meets the standards; mechanical performance testing to test the tensile strength and elongation at break of the cable to evaluate its mechanical performance; and special performance tests such as oil resistance, heat resistance and water resistance to verify whether the cable meets the design standards. Only cables that pass all tests can leave the factory for sale.

Transportation mode: According to the customer's geographical location, order quantity and delivery time requirements, select the appropriate transportation mode. For domestic customers, road transportation is usually adopted. Road transportation has the characteristics of high flexibility and fast delivery speed, which can meet the delivery needs of most customers. For large quantities of orders, railway transportation can also be used, which has the advantages of large transportation volume and low cost, and is suitable for long-distance transportation. For export customers, sea or air transportation is adopted. Sea transportation is suitable for large quantities of orders with low timeliness requirements and low cost; air transportation is suitable for small quantities of orders with high timeliness requirements, which can quickly deliver products to customers.

Protection during transportation: During transportation, the cables need to be properly fixed and protected. For reel-packaged cables, they are neatly stacked in the cargo compartment of the transport vehicle, and the reels are firmly fixed with ropes or fixing devices to prevent the reels from rolling and colliding due to vehicle bumps and turns during transportation, resulting in cable damage. For coil-packaged cables, they also need to be fixed to avoid mutual extrusion and friction. The cargo compartment of the transport vehicle needs to be kept clean and dry to prevent the cable from contacting harmful substances such as oil and water. During transportation, attention should also be paid to avoiding direct sunlight and high-temperature exposure of the cable to prevent aging of the cable surface.

Transportation tracking: The company has established a perfect transportation tracking system, and customers can query the transportation status of the cable through the order number and other information. During transportation, the logistics company will regularly feedback transportation information to the company, such as the location of the goods and the transportation progress, and the company will also timely inform customers of this information, so that customers can know the situation of the goods in real time. If there are abnormal situations during transportation, such as transportation delay caused by traffic jams and bad weather, the company will timely communicate with customers and negotiate solutions.

Order processing: After the customer places an order, the sales department will promptly transmit the order information to the production department and the warehouse department.
