Earth Rods
Pure Copper Molecularly Bonded Onto Steel Core Rod
T&D distribute the complete range of copperbond earth rods offering installers the most economical method of achieving a low earth resistance for earthing system designs – each copper earth rod has a high tensile strength and low carbon steel core.
99.95% pure copper is applied electrolytically forming a metallurgical bond between the steel core and the copper. This combination makes the copper earth rod ideal for deep driving whilst also provides lasting resistance to corrosion in aggressive soil and ground conditions.
The standard copper earth rod thickness is 0.25mm – copper bonded or clad extensible earth rods are commonly specified as part of the construction and design of UK DNO earthing systems according to ENA TS 41-24. In applications recording higher than average soil resistivity additional earth rods are usually installed at each distribution substation – vertical rods or horizontal tapes are used to reduce surface currents and/or the electrode resistance of the overall earth electrode system while controlling step/touch potentials in outdoor substations.
Copperbond earth rods are available with 1/2″, 5/8″ and 3/4″ diameters and thread sizes 9/16″, 5/8″ and 3/4″ according to UNC-2A – solid copper earth rods also available.
