Analysis Of The Arc Breakdown Resistance Of Copper-clad Grounding Rods

In high-voltage or lightning strike situations, the arc root borne by copper plated ground rod tends to switch at the interface between the rod and the surrounding soil/air. If the copper cladding of copperbond earth rod is tightly bonded to the steel core and the material conductivity is stable, earth bonding rod can share the arc energy release in a very short time. In this structure, the arc extends from the metal surface to the nearby soil, and the copper cladding of ground rod 3 4 x 10 provides a good conduction path, allowing the arc root to extend along the rod rather than penetrating the cladding to enter the steel core.
