Earth rods or copper rodand their fittings are used to offer the interface to ground in all soil conditions in order to achieve acceptable earthing systems in above and underground electricity distribution as well transmission networks – providing high fault current volume on low, medium and high voltage substations, towers as well power distribution applications. Suitable to install where the subsoil condition is free from rock and boulders the earth rod or group of copper rods can be surrounded or backfilled using a low resistance material such as Bentonite. Depending on the eroding condition and electrical conductivity of the ground condition the earth rod can be definite to achieve safe, consistent and long term earthing protection – the mechanical strength of the rod must withstand the abrasion and stress suffered while installing with an electric or inflated driving rod hammer; the head of the earth rod should not “mushroom” or spread when driven.
Copper Earth Rods– These rods are industrial from high tensile-low carbon steel. All the rods are molecularly attached by 99.99% pure, high conductivity copper bondings, each & every rod is preserved with Benzol-triozolespinoffs. Roll threading procedure is used in order to form the threads on the rods. Which in turn offer the threads with the extra strength, that is compulsory to eliminate the risk of chipping the threads while driving the rods in the ground.
Solid Copper Earth Rods- These rods are framed in two different manner- Outwardly threaded and internally threaded. Solid Copper earth rods are typically used in the applications, where the corrosion factor is very high and remarkably long life is vital. Therefore, these rods are precisely manufactured from pure and high conductivity hard drawn copper.
