Earthing Materials
It has characteristics as below
1. Thickness of the copper layer is more than 0.254mm.
2. The advantages are good tensile strength more than 600N/mm2.
3. Our ground rods can be bended through a 30 or 90 or 135 degrees angle, and the rods will be no evidence of cracking or splitting of the steel or the copper cladding.
4. Good in anticorrosionthat usage-life is more than 50 years or more, constant low resistance and good plasticity which had the characteristics of copper as well as steel.
Note
1.Diameter standardis 11mm, 12.5mm, 14.2mm and Φ17.2mm, the thread size for 1/2", 9/16'',
2.We can supply you earth rods with much more thickness of copper layer such as 25 microns,
3.Also, we can supply you earth ro with two ends thread, Un-thread but with one end point,
4.Length of earth rod as your request.
