Earthing System confirming IS 3034. The outer and inner pipe should be 76.2 mm & 41.9 mm 3mtrs Length, Zinc coated with additional special Alloy coating 300mm on the topside for additional corrosion protection of the Terminal. The annular space between the pipes being filled up with COMPACT FILL(CF) (Crystalline Conductive Compound). The COMPACT FILL (CF) mixture which is machine pressed in the pipes should not disintegrate or collapse when outer pipe corrodes. The inner pipe should be extended with terminals for connectivity The job includes digging the pits and refilling the same by Conductolite Back Fill compound (Ground Enhancer)-02begs, the BFC should be eco friendly it should not contain environmentally hazardous material/metal having RoHS Certification from NABL accredited lab. Good earth is to be arranged to fill the excavated pits by mixing the 2 bags electrodite BFC in soil. including FRP (Fiber reinforced plastic) light weight, high mechanical strength, chemical resistance with detachable easy locking lid of size 250mm X 250mm of thickness 2mm,The eart pit has been excavated 1mx1mx3m depth and filled by black cotton or good normal soil mixed with 2 beg of BFC Electrodite complete all as specified and directed.

The earth pit should be provided with a FRP earth pit cover for protection and safe guard of terminals. the earth pit has been excavated 1mx1mx3m and filled with, G00D EARTH ie Black cotton or moistures normal soil is to be arranged to fill the excavated pits by mixing the arranged soil with BFC 2 Electrodite & 2 bags Conductolite BFC for installation of earth Electrode. As the earth electrode is the main component of the Earthing system which is in direct contact with the ground and thus provides a means of releasing or collecting earth leakage currents. The material should have good electrical conductivity & anti corrosion property in wide range of soil conditions. Note:Earth strip for connection has been measured and paid seprately.The earthing value should be less than 2 Ohms for single earth Make “ASHLOK”Model-ASEEL-19/3M length (ZC & AC) (All the above given dimensions may vary ± 1 MM) OR Make “INDELEC”, “MACMATE”
