Chemical Earthing-Pipe in Pipe

In this technology, there are two pipes of different diameters. The smaller dia pipe (main conductor) is placed centrically inside the bigger dia pipe (outer pipe) and space inside the electrode is tightly filled with a crystalline conductive mixture (CCM) and then sealed. The crystalline mixture contains natural elements and compounds, which are high conductive as well as anti corrosive.

Installation method of welkin Electrode: Bore a hole of 4 to 6 Inch in diameter at a place where earthing is to be done, to a suitable depth of 2 to3 meters (welkin Electrode Length)Place the Earthing Electrode inside the pit. The back fill compound Re-Fill the empty space around the Earthing Electrode with this compound .While re-filling the space, pour adequate water in the PIT.Pack the soil around the Electrode tightly.Again pour adequate water at least 3 to 4 feet around the Earthing Electrode.Test the earth resistivity of the Electrode and if the result is satisfactory, then connect it with the equipments.If the result is not satisfactory, then allow the Electrode some time (2/3 days) for setting of the soil and then check it & connect it.If the soil is of high resistivity i.e. Semi rocky or rocky soil, use extra back - fill compound for refilling the PIT.


It is a specially developed compound which is capable of absorbing and retaining the moisture for 20 times to its dry volume, it reduces the soil resistivity, to some extent it helps in faster dissipation of fault current, least fluctuation of ohm value and it eliminates the use of salt, charcoal etc. around the earthing electrode. It is a combination of natural earth minerals & CCM ( Crystiline Conductive Minerals) with graphite powder. Its having the natural properties to make a grip with any metal, when it comes with the contact of water. It is totally corrosion free eco-friendly compound.

Do not drop the welkin Earthing Electrode.Do not subject it to any kind of driving force.Do not hammer it while installing the Electrode.Do not use it other than the purpose of Earthing.Remove the packing cover before installing the electrode.Always, place the Electrode keeping the connecting terminal on top.Apply petroleum jelly over the exposed part (Terminal) of the Electrodes to safe guard it against the corrosion.
