Material Considerations For The Arc Breakdown Resistance Of Copper-clad Grounding Rods

bonded rod Due to the use of a copper and steel combined structure, a continuous conductor layer is formed on the metal surface while maintaining the mechanical strength of the internal steel core. This structure helps copper bonded to conduct the electric arc along the rod to the soil environment under high voltage impact, making it less likely to penetrate into the steel core and adversely affect the overall electrical stability of the material.

Arrow breakdown resistance involves the material's conductive path and local electric field distribution characteristics. As a good conductor, the continuity and thickness of the copper capping layer directly affect conductivity and the morphology of the arc root extension path. High-quality copper layers can provide a low-impedance path during arc impact, making the current distribution more uniform between the copper bonded earth rod price and the surrounding soil, and reducing the impact of local electric field peaks on the steel core boundary.
