Pipe-in-Pipe technology. Two B Class IS mild steel pipes, one inside the other, hot dip galvanized with 100 micron coating outside and about 300 micron coating inside, filled with High conductive and Corrosion Resistant Crystalline Mixture plus Backfill Compound around electrode.

Two models available:
Model T-19, 50 mm dia, 3 meter is used in place of the conventional GI Pipe earthing. (LV/MV)
Model T-39, 76 mm dia, 3 meter is used in place the conventional copper plate earthing. (HV/EHV)

Copper plate earthing inclusive of MS Pipe, 50 mm dia, 2.75 meter long, copper plate 450 x 450 x 3 mm with copper strip 25 x 3 - 6 nos plus charcoal and salt around electrode. Oxidation takes place. Resistance to dissipation starts after about 6 years.

G I Pipe Electrode Earthing: 15 - 20 micron galvanization. Size: 65NB or 38 mm x 2.75 m long PLUS Charcoal & Salt etc. Pipe corrodes fast over a period of 3 years causing high resistance to smooth dissipation of current.

Own Backfill Compound is used as infill material. BFC retains moisture 13 times its dry volume; enhances conduction around the electrode. Excellent backfill material substantial reduction of resistance of earthing system in highly resistive soils.

Charcoal & Salt are used in the pit as in fill material. Common salt hastens corrosion of GI/CI electrodes and the ohmic value goes high over a period of time

Watering around the earth pit is required for about 15 days after installation and for a few days in peak summer when water table goes down.

Ohmic value always within safe limits.

Ohmic value fluctuates resulting in frequent maintenance of costly machinery and appliances and danger to human life.

Maintenance of pit is not required in normal soil conditions.

Maintenance of earth pit required at regular intervals.

Low enough impedance to activate fault relays. Due to high conductive soil around the electrode, charge dissipation through electrode is very high, current density across electrode is very low, which results in very high fault current enough to trip fault relays.

Sometimes fails to activate safety devices. Distribution of short circuit current is less in terms of charge dissipation and, therefore, generates high potential at the pit resulting in low fault current, insufficient to trip fault protection relays

Always provides safe discharge path to fault current and lightning current.

Some times fails to provide safe discharge path for fault current

Requires less space and time for installation.

Requires large space and time for installation.

Practically no need to change. Expected average life 15 + years in normal soil condition

GI Pipe earthing needs to be changed every 3 years and copper plate earthing every 12 years due to corrosion attacks.

Our Backfill Compound is not soluble in water.

Salt as infill material is washed away during rainy season.

Very safe and stable platform for electronic machinery, equipment and appliances.

Not a stable platform for sensitive electronic equipment and appliances
