The Role Of Conductivity Of Copper-clad Grounding Rods In Grounding Systems

copper bonded steel rod During the grounding process, the current needs to be quickly conducted to the underground soil. In this type of composite structure, the outer copper layer undertakes the main conductivity task. Copper's conductivity is much higher than that of ordinary steel; therefore, when copper clad ground rods is in the current transmission link, the copper layer directly affects the potential distribution and current resistance. copper coated earthing rod Compared to pure steel, it exhibits significant differences in conductivity and resistance, maintaining a low impedance level in soil at a certain depth.

copper plated ground rod The conductor performance variation is related to the copper layer thickness and manufacturing process. Standardized electroplating or hot-dip immersion processes ensure a uniform copper layer covering the rod, guaranteeing stable conductivity even under varying soil moisture and chemical composition conditions. This material combination is evident in the response under high-frequency or pulsed currents.
