Earthing Rods
UL Listed earth rods — tested to IEC 62561, BS EN and UL standards.
Copperbond, solid copper and stainless steel earth rods for driven earthing systems — diameters from 12.5mm to 25mm, lengths up to 3000mm, with the driving studs, coupling dowels and spikes to install and extend them.
The Earth Rod Range
Earth rods form the earth electrode of the earthing system — driven into the ground and connected to the conductor network to give fault and lightning currents a low-resistance path to earth.
Unitech manufactures three earth rod families: copperbond rods with a copper jacket over a high-tensile steel core, solid copper rods and stainless steel rods — covering the full run of soil conditions and specification requirements across infrastructure, power, rail and building projects.
Every diameter and length in the range is listed below with its part number. Threaded copperbond rods join together with coupling dowels, so an electrode can be extended section by section to the depth the site requires.
- Copperbond to IEC 62561-2 — 254 microns of 99.9% pure electrolytic copper jacket over a low-carbon, high-tensile steel core (AISI-1018, UTS 600N/mm²).
- UL Listed earth rods — tested to IEC 62561, BS EN and UL standards.
- Threaded & non-threaded — every copperbond size is available in both versions, with part numbers for each.
- Extendable — threaded rods couple together with coupling dowels to reach greater driving depths.
- Custom sizes on request — non-standard sizes and copper thicknesses can be supplied.
Copperbond Earth Rod — To IEC 62561-2
- Steel core: low carbon high tensile steel, AISI-1018 (SAE-1018), UTS = 600N/mm²
- Copper jacket: 254 microns of 99.9% pure electrolytic copper
