Copper Bonded Ground Rods are the ideal driven earth rod as they offer the installer an economical and efficient earth rod grounding system. Pure electrolyte copper is uniformly molecularly bonded into a high tensile steel core to a minimum thickness of 300 microns (0. 3 mm), thus ensuring excellent corrosion resistance and eliminating electrolytic action. Coupling threads are formed by a rolling process to ensure thread strength and to maintain the integrity of the molecularly bonded copper.
A good earth should have low electrical resistance to earth, good Corrosion resistance, and ability to carry high currents repeatedly, a reliable life of at least 30 years. It is available in 14mm , 17 mm dia with standard length of 1.2mtr, 2mtr, 3mtr .
