Ground Rods

We are recognized as one of the trustworthy manufacturers of a wide range of Earth Rods. Ground rods manufactured to standard specifications using copper and copper alloys. Ground rods are used in electrical grounding applications in a variety of industries. Specifications include Copper Earth Rod, Copper Bonded Rods, Threaded Copper Bonded Earth, Solid Copper Earth Rods, Copper Grounding Rods, Copper Clad Earth Rod, Copper Coated Earthing Rod, Galvanized Steel Earth Rods, Stainless Steel Earth Rods, Chemical Earthing Rods.

Ground rods and their fittings are used to provide the interface to ground in all soil conditions in order to achieve satisfactory earthing systems in overhead and underground electricity distribution and transmission networks – providing high fault current capacity on low, medium and high voltage substations, towers and power distribution applications.
Convenient 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 earthing material such as Bentonite.
Depending on the corrosive condition and electrical conductivity of the ground condition the earth rod can be specified to achieve safe, reliable and long term earthing protection – the mechanical strength of the rod must withstand the abrasion and stress endured while installing with an electric or pneumatic driving rod hammer; the head of the earth rod should not “mushroom” or spread when driven.
The earth rods, manufactured we, are extendable by design and used with copper couplers to inter-connect several rods to achieve the required driving depth – the rod couplers provide permanent electrical conductivity and the longer copper earth rods access lower resistivity soils at at lower depths.
Vertically driven earth rods are the most effective electrode for use in typically small area substations or when low soil resistivity ground conditions, into which the rod can where the rod can penetrate, lies beneath a layer of high soil resistivity.
Rule of thumb – doubling the radius of the earth rod will reduce resistance by approximately 10% and is not a cost-effective option. Doubling the rod length however will theoretically reduce resistance by 40%.
Where additional driven earth rods are combined and connected they should be separated from each other and from any adjacent cables by a distance not less than the depth to which they are driven. Additional earth rods should be connected using copper tape or bare copper cable of the same cross sectional area as the earth electrode conductor. The additional electrodes should be placed so that any necessary separation of the LV and HV earth electrode systems is maintained.
