Electrode Rod Component – Electrical Equipment Manufacturing

Component Specifications

Definition

The electrode rod is a critical component of an earth electrode system, typically made of copper or copper-clad steel, designed to provide a low-resistance path for electrical fault currents to safely dissipate into the earth. It is driven vertically into the ground and connected to the electrical system's grounding conductor.

Working Principle

When a fault occurs, the electrode rod conducts the fault current into the surrounding soil, where it disperses. The rod's low resistance ensures minimal voltage rise, protecting equipment and personnel.

Materials

Copper-clad steel (minimum 10% copper thickness) or solid copper, with a diameter of 14-20 mm and length of 1.5-3 m.

Technical Parameters

Length 1.5-3 m
Diameter 14-20 mm
Copper Thickness ≥ 250 microns
Tensile Strength ≥ 600 N/mm²

Standards

IEC 62561-2, UL 467, BS 7430
