These systems provide long life to equipment, safety of the personnel, does not require any maintenance as well as reduces the maintenance cost. Sabo make chemical earthing system provides low resistance path in ground to any fault & leakage currents and ensure the smooth flow of the ground dissipation.
Sabo earthing electrode consists of primary earthing electrode (outer pipe) and secondary earthing electrode (inner pipe). The secondary electrode is inserted inside the primary electrode and the process of hot dip galvanization is well performed to a level of 80 – 100 microns. The galvanization is performed to ensure the log life of the earthing rods against any corrosion when it is exposed to the contact of the soil.
The space between the outer and inner pipe is duly filled with a highly conductive and non-corrosive compound which safeguards the earthing electrode getting corrode over a long period of time under the soil. Also the conductive compound ensures the easy distribution of leakage/fault current if it is landed on the earthing electrode.
Both the ends of the earthing electrode are permanently sealed and a lead terminal is provided at the top with the 2 holes on the terminal for connecting to the load/equipment.
Depending upon the soil conditions, back fill compounds are selected to install along with the earthing electrode. Reslow grounding minerals are selected for normal soil conditions & Carbofill grounding minerals is selected for rocky/sandy soil conditions.
