A Copper-Bonded Earth Rod is an electrical grounding electrode made of a high-strength steel core bonded with a layer of copper. It provides a low-resistance path to safely dissipate fault currents and lightning surges into the ground, protecting electrical systems and equipment.
Copper-bonded earth rods are widely used in residential, commercial, industrial, and utility grounding systems. The steel core provides mechanical strength for driving into the ground, while the copper coating offers excellent conductivity and corrosion resistance. They are typically installed with earth clamps, couplings, and driving heads to achieve the required grounding depth and resistance.
