Deep Driven Rods are preferred where the soil resistivity decreases with depth. These rods help to reach stable grounds, such that the value of the electrode resistance remains stable even if the top layers of the ground dry out. As per customer requirement Extendable Copper Bonded Rods with internal threads or external coupler can be provided.

7 Nos. of Cast Iron Plate 1.2m x 1.2m x 12.5mm for a fault current of 7.87kA in 100ohm-m soil resistivity can be reduced to 5 Nos. of Extendable Copper Bonded Rod 40mm dia. 6mtr Long /7 Nos. of 32mm dia. 6mtr Long. Extendable Copper Bonded Rods are used for Transformer Neutral and Body Earthing reducing the overall cost and area required for installation in a more efficient manner.
