Package
Production Line
The production of 1.5mm solid electrical ground cable involves several key steps on a specialized cable manufacturing line. First, high-purity copper rods are drawn into solid conductors of precise diameter. The conductors then pass through an insulation extrusion process, where durable PVC is applied evenly around the copper. After cooling, the cables undergo cutting, marking, and quality inspection, including checks for conductor continuity, insulation thickness, and surface defects. This streamlined production line ensures consistent electrical performance, safety, and long-term reliability of every cable batch.
