Why To Choose Copper Bonded Earthing Rods

Many times, engineers are given the choice between three types of ground rods: copper-bonded steel, copper clad ground rods or galvanized steel for grounding systems. However, one material reigns supreme when it comes to strength, service life and overall investment. Hint: it copper bonded steel.

Continue reading below to learn why copper is the better choice for grounding systems versus it steel alternative.

1. Stronger Characteristics for Dependable Service Life

Engineers should aim for ground rods that have a strong core for the ease of driving into the earth and high corrosion resistance. Copper-bonded ground rods have a high carbon steel core that is suitable for deep driving. A layer of nickel and then a coating of copper are electroplated on the steel core to provide corrosion protection this coating is not subject to the risk of bending or cracking.

Alternatively, copper clad steel ground rods are more likely to develop cracks and creases to the outer sheath. Additionally, galvanized steel ground rods have a higher corrosion rate, which will significantly reduce serviceable life and put the integrity of the entire electrical system at risk.
