PVC Insulation Copper Electrical Wiring Earth Wire Cable: Essential Safety for Electrical Systems​ This range of PVC-insulated copper earth wire cables, available in 2.0mm, 5.5mm, 8mm, and 50mm, serves as a critical safety backbone for electrical systems, designed to divert fault currents safely to the ground. Crafted with high-purity copper conductors, they ensure low resistance and efficient conductivity—vital for rapid dissipation of electrical surges, minimizing risks of electric shock, equipment damage, or fires.​ The PVC insulation layer, engineered for durability, offers robust protection against moisture, abrasion, and temperature extremes (-15°C to 70°C), making it suitable for both indoor and outdoor installations. Its flame-retardant properties add an extra safety barrier, slowing fire spread during electrical faults. The insulation also features clear color coding (typically green/yellow) for instant identification, complying with global safety standards (IEC, UL) to prevent misconnection.​ Each 规格 (specification) targets specific applications: 2.0mm for residential grounding (appliances, lighting); 5.5mm and 8mm for commercial use (distribution panels, HVAC systems); and 50mm for heavy-industrial settings (power plants, renewable energy facilities). All variants balance flexibility and strength, facilitating easy routing through conduits or tight spaces.​ Compliant with international codes, these earth wires deliver reliability across residential, commercial, and industrial projects. Their combination of high-conductivity copper, durable PVC, and tailored sizing makes them an indispensable choice for ensuring electrical system integrity and safety.

As a professional manufacturer of electrical safety cables, we are committed to providing high-performance 70mm² Electrical Earthing Cable—a critical component designed to safeguard electrical systems, equipment, and personnel by diverting fault currents to the earth. This cable stands out in industrial, commercial, and large-scale residential projects for its excellent current-carrying capacity, robust mechanical strength, and reliable conductivity, making it an indispensable choice for high-demand earthing applications.​ The 70mm² cross-sectional area is the core advantage of this earthing cable, enabling it to handle large fault currents (up to 2000A under short-circuit conditions) efficiently. Unlike smaller-gauge earthing cables (such as 25mm² or 50mm²), the 70mm² variant minimizes resistance during fault current diversion, ensuring rapid dissipation of dangerous currents to the ground—this is crucial for preventing electrical shocks, equipment damage, and fire hazards in high-power systems (e.g., industrial machinery, commercial building main switchboards, and renewable energy installations like solar farms).​ Constructed with high-purity stranded copper conductors (99.95% oxygen-free copper), the cable delivers exceptional conductivity and flexibility. The stranded design, composed of multiple thin copper strands twisted together, allows easy installation in tight spaces, around equipment corners, or across long distances without compromising conductor integrity—solving the rigidity issue of solid-core cables and adapting to complex on-site environments. The cable is also coated with a durable, corrosion-resistant PVC or XLPE (cross-linked polyethylene) insulation layer: PVC insulation offers excellent moisture resistance for indoor or mild outdoor use, while XLPE insulation provides enhanced high-temperature tolerance (up to 90°C continuous use) and UV resistance, making it suitable for harsh outdoor conditions like power transmission towers or outdoor substation earthing systems.​ Our 70mm² Electrical Earthing Cable complies with international standards such as IEC 60446 (for earthing conductors) and GB 50169 (China’s national standard for earthing engineering), undergoing strict quality testing including resistance measurement, tensile strength verification, and corrosion resistance assessment. These certifications ensure the cable meets the highest safety requirements for long-term, stable operation.​ As a customer-centric supplier, we offer flexible customization (e.g., adjusting cable length, choosing insulation materials based on application environments) and professional technical support—our team assists clients in calculating earthing system requirements, selecting matching accessories (like earthing clamps and lugs), and providing on-site installation guidance. Whether for new project construction, electrical system upgrades, or safety compliance renovations, our 70mm² Electrical Earthing Cable delivers the safety, reliability, and performance needed to protect electrical infrastructure.
