This high voltage grounding cable is manufactured in accordance with IEC, national standards and international mainstream power industry standards. It adopts high-purity conductive conductor and high-strength protective structure with stable and smooth conductive path and controllable uniform resistance value. Specially designed for power grounding working conditions, the cable can withstand long-term power frequency fault current and instantaneous lightning impact current with high current discharge efficiency. It effectively balances the grounding potential difference of the power grid and eliminates static accumulation and potential drift of high-voltage equipment.

FAQ
Q: Is insulation protection necessary for high voltage grounding cable?
A: Both bare and insulated types are available. Insulated cables are recommended for indoor cabinets and dense equipment areas to prevent short circuits. Bare conductors are more cost-effective and ideal for outdoor and buried grounding projects.
Q: Why is stable resistance important for grounding cables?
A: Stable resistance ensures fast and uniform discharge of fault current, prevents potential deviation and equipment counter-attack damage, and guarantees safe and stable operation of the entire high-voltage power system.
Q: How to choose conductor material for different environments?
A: Pure copper is the first choice for standard projects with high conductivity and stability. Copper-clad steel is suitable for coastal and corrosive areas. Aluminum alloy is applicable for temporary projects to control costs.
