定义
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.
工作原理
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.
材料
Copper-clad steel (minimum 10% copper thickness) or solid copperwith a diameter of 14-20 mm and length of 1.5-3 m.
Length
1.5-3 m
Diameter
14-20 mm
Copper Thickness
≥ 250 microns
Tensile Strength
≥ 600 N/mm²
标准
IEC 62561-2UL 467BS 7430
