copper Bonded Earth Rods

It has characteristics as below:

1.Thiclcness of the coppeo layer is more than 0.254mm.
2.The advantages are good tensile strength more than 6QON/mm2
3.0ur 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 anti corrosion that 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 standard is 11 mm,12.5mm,14.2mm and ∅1 7.2mm ,the thread size for 1/2”,9/16',5/8'and 3/4'and also can make metric standard.
2.We can supply you earth rods with much more thickness of copper layer such as 25 microns.50 microns,100 microns.127 microns, 254 microns and 330 microns etc.
3.Also, we can supply you earth rod with two ends thread,Un-thread but with one end point, one end thread and the
other end point.
4.Length of earth rod as your request.

Formula of calculating for single earth rod:

R:Earthing resistance of single earth rod (Q)
p:Earting resistance rate after revised(Ω-m)
L:Length of earth rod(m)
d:Diameter of earth rod(m)
