HV Earth Rod/ Earthing Wire

Earth Rod

As a vertical grounding electrode for power systems and lightning protection projects, it provides a stable low-resistance grounding path, widely used in substations, transmission lines, distribution stations and industrial equipment grounding scenarios. Process & Material: The core is made of high-quality low-carbon steel, uniformly coated with high-purity electrolytic copper (copper layer thickness ≥0.25mm) via continuous electroplating process, with molecular-level bonding between copper and steel that ensures no peeling or cracking when bent. Equipped with high-strength alloy steel driving head and alloy tip for driving into complex geological conditions. The uniform and dense surface coating delivers C5-grade corrosion resistance, with a service life of over 30 years in outdoor underground environments. Standard Specifications: Diameter Φ14mm~Φ20mm; standard single length 1.5m / 2.4m / 3m; extendable via threaded connection up to 35m depth. Hot-dip galvanized steel, pure copper and stainless steel materials are also available.

Earthing Cable

A temporary safety earthing device for power maintenance work, which quickly discharges residual charge on de-energized equipment/lines to prevent personal injury caused by unexpected voltage. It is an essential safety tool for line operation & maintenance and substation construction. Process & Material: The conductor is made of multi-strand high-purity annealed soft copper strands, with single wire diameter ≤0.4mm for excellent flexibility and no strand breakage. The outer layer is covered with weather-resistant insulating sheath for wear and cold resistance. The clamps are made of high-pressure die-cast aluminum alloy with tight bite and low contact resistance. Matched with epoxy resin insulating operating rods for stable insulation performance and safe handling. Standard Specifications: Copper conductor cross-section 10mm² / 16mm² / 25mm² / 35mm² / 50mm² / 95mm²; suitable for voltage levels from 0.4kV to 500kV; clamp types include flat screw type, double-spring snap type and throat type, adapting to busbar, conductor and different wiring scenarios; operating rod length can be selected on demand.
