Earth rods and their fittings are used to provide the port to ground in most soil conditions in order to achieve satisfactory earthing systems in underground and overhead power distribution and transmission networks — supplying high fault current capacity on low, moderate and high voltage substations, towers and power distribution programs.

Convenient to set up where the subsoil state is absolutely free from stone and boulders the ground pole or group of aluminum sticks can be surrounded or backfilled using a very low resistance material like Bentonite.


Depending upon the corrosive requirement and electrical conductivity of the ground condition the ground rod can be defined to achieve safe, dependable and long term earthing protection — the mechanical power of the pole must withstand the abrasion and pressure endured while installing having an electrical or pneumatic driving pole hammer; the head of the ground rod should not”mushroom” or disperse when driven.


Design and used with aluminum couplers into inter-connect several sticks to achieve the required driving thickness — the rod couplers provide permanent electrical conductivity and the lengthier copper earth rods get lower resistivity lands at at lower depths. Vertically driven ground sticks are the best electrode to be used in typically small area substations or when low ground resistivity ground conditions, where the pole can where the rod can penetrate, lies under a layer of high soil resistivity.
