Earthing Electrodes

Pipe-style earthing electrodes for heavy machinery and infrastructure grounding

Earthing electrodes are pipe-form grounding solutions designed for installations requiring large surface area and high fault current capacity. Available in copper-bonded or zinc-galvanized variants, Norton Power electrodes are manufactured from medium and heavy quality low carbon mild steel pipe in diameters from 50mm to 100mm — the configurations specified in government tenders and large industrial projects.

Each electrode comes with a clamp or terminal at the top for connecting earthing strips or wire, and is designed to IS 3043:1987 specifications. The pipe form provides significantly more soil contact than rod electrodes, making these the right choice when fault currents are high or when soil resistivity demands maximum surface area.

Frequently asked questions

When should I use a pipe electrode vs a rod electrode?

Pipe electrodes are preferred when fault currents are high or soil resistivity is poor — the larger surface area provides better contact with the earth. Rod electrodes are sufficient for most distributed grounding needs.

What's the difference between copper bonded and galvanized electrodes?

Copper bonded electrodes offer 40+ year service life and lower long-term resistance. Galvanized electrodes have a lower upfront cost but typically need replacement within 8-12 years due to corrosion.

Do you provide installation accessories with the electrode?

Yes. Electrodes ship with the standard clamp/terminal. We can supply complete kits including earth enhancing compound, pit covers, and connecting strips on request.
