The 1 core 10-35mm² pure copper grounding cable is a safety-oriented cable specially designed for electrical earthing systems. It adopts a double-layer protection structure of green/yellow PVC insulation and PE sheath, with a rated voltage of 450/750V. It is widely used in grounding devices of various buildings, industrial facilities and power projects, providing key protection for electrical equipment and personnel safety.​ This series of cables covers four specifications: 10mm², 16mm², 25mm² and 35mm², which can be flexibly selected according to the current carrying requirements of the grounding system. The 10mm² is suitable for grounding of small power distribution equipment and household circuits; the 16mm² is adapted to the grounding of lighting and power systems in commercial buildings; the 25mm² and 35mm² are mostly used in main grounding circuits of large electrical facilities such as industrial plants and substations, ensuring that fault current is quickly introduced into the ground to avoid equipment damage or personal electric shock accidents.​ The core advantages lie in the collaborative design of materials and structure: the conductor is made of high-purity electrolytic copper, which has excellent conductivity, can minimize the grounding resistance, and ensure the efficient discharge of fault current. The green/yellow PVC insulation layer not only conforms to international grounding identification standards for quick identification, but also has good weather resistance and insulation performance, which can resist the impact of moisture, dust and other environments; the outer PE sheath further enhances the mechanical strength of the cable, with outstanding wear resistance and corrosion resistance, adapting to complex installation environments such as underground burial and wall pipe penetration.​ The rated voltage of 450/750V perfectly matches the low-voltage distribution system, and can be directly connected to various grounding terminals without additional adaptation. The production process strictly follows international electrical safety standards and passes multiple tests such as grounding resistance, insulation withstand voltage and aging resistance to ensure stable performance during long-term use. Whether it is the laying of grounding systems in new projects or the upgrading of old systems, this cable can provide a reliable grounding path and is a core component to ensure the safe operation of electrical systems.
