Copper Grounding Rod vs Galvanized Rod – Differences and Benefits

Grounding copper rods are also often more effective than galvanized rods since they offer superior electrical conductivity. The enhanced conductivity allows electrical systems to transfer excess electrical charges away from the system, reducing the possibility of failure in electrical systems. With copper wires enabling low wire resistances as well, performance in the grounding of structures such as sites is much improved. Obviously coppe wiring would be used in more critical installations.

Many industrial processes utilize copper in areas where it will not be readily painted or coated, as there is a strong market for this metal and supplies are readily available. Copper also lacks the ability to rust or corrode easily, therefore increasing the overall lifetime of the grounding systems. Galvanized rods are also coated to stop rust from forming, however these coatings would eventually weather and fail especially in harsh environments. The durability of copper moving rods means that grounding systems require frequent offers replacements, thereby bringing down repair costs and ensuring the electrical systems are intact for a prolonged period.
