What are copper bonded earthing rods and how do they work?

In general, a COPPER BONDED EARTHING ROD is considered a grounding electrode to safely disperse fault currents through the earth, thereby protecting the electrical systems and structures associated with it. The rod has a low carbon steel core molecularly bonded with a layer of copper which has high electric conductivity. This means the rod has very high mechanical strength while also resisting corrosion effectively, thus ensuring it's a long-lasting and efficient ground solution.

The operating principle of a COPPER BONDED EARTHING ROD is to provide a low-resistance path to the earth. That is, in case of any fault or lightning strike, the current safely flows to the ground through this rod. The coating of copper offers good conductivity with very low resistance, and at the same time, the steel core provides strength to push the rod deeper into the soil. They are usually found in a substation, industrial plants, communication towers, and residential areas.

The design advantage of these rods allows them to keep grounding consistently even with an aggressive soil-condition. Besides, copper bonded earthing rods need less maintenance than galvanized rods, due to their high corrosion resistance.

To conclude, the COPPER BONDED EARTHING ROD turns out to be a dependable and maintenance-free earth solution that ensures both safety and efficiency for a wide variety of electrical and industrial uses.
