The production process of the green-yellow grounding wire is exquisite, and each link is strictly controlled and inspected to ensure the high quality and performance of the product.

The first is the processing technology of the conductor. High-purity electrolytic copper ingots are selected as raw materials, and copper rods are made through smelting, casting and other processes. Then, the copper rod is drawn into a single copper wire with the required diameter by a wire drawing machine. During the wire drawing process, the speed, force and temperature of wire drawing are precisely controlled to ensure that the diameter of the single copper wire is uniform, the surface is smooth, and it has good mechanical properties and conductivity. After wire drawing, the single copper wire is annealed to eliminate the internal stress of the copper wire, improve its flexibility and ductility, and prepare for the subsequent stranding process.

Next is the conductor stranding process. Multiple single copper wires are precision stranded according to a certain stranding method and pitch to form a multi-strand conductor. During the stranding process, the tension and speed of stranding are strictly controlled to ensure that the single copper wires are closely combined and evenly distributed, avoiding looseness or breakage. The multi-strand stranding process not only increases the flexibility of the conductor, but also improves the conductivity and heat dissipation performance of the conductor. After stranding, the conductor is inspected for appearance and measured for size to ensure that it meets relevant standards and design requirements.

Then is the extrusion process of the insulating sheath. The stranded conductor is fed into the extruder, and a layer of special heat and moisture resistant PVC composite material is extruded on the outer layer of the conductor as the insulating sheath. During the extrusion process, the temperature, pressure and speed of the extruder are precisely controlled, so that the PVC composite material can be evenly wrapped on the outer layer of the conductor to form an insulating sheath with uniform thickness and smooth surface. The thickness of the insulating sheath is precisely controlled according to different specifications and models to ensure that it has good insulation performance and mechanical properties. After extrusion, the insulating sheath is cooled and solidified to make it closely combined with the conductor.

During the production process, semi-finished products will undergo multiple quality inspections, such as conductivity testing of conductors and insulation performance testing of insulating sheaths. After production, the finished products will undergo comprehensive performance tests, including heat resistance testing, moisture resistance testing, mechanical performance testing and many other rigorous tests. Only products that pass all tests can leave the factory to ensure that the quality and performance of the products meet relevant standards and requirements.

In addition, in the production process, attention is paid to environmental protection and safety.
