Amount

M&L for taking out old unsv earthing and material and labour for maintenance free grounding Solution set earthing comprising of Earthing rod , outer pipe in GI and having minimum diameter of 76mm, 3m in length and inner pipe to have minimum diameter of 32mm, both end properly welded to make them airtight. GI terminal size of 100x50x6mm with 2 Nos M8 holes for termination area in between two pipes filled with dry type chemical powder having high conductivity and make sure no air pockets are left. Electrode must be tested for short circuit test of minimum 40 KA at CPRI/NABL. The earthing electrode will be placed in the ground after a bore is drilled to the depth of 3.5 Mtr. The bore drilling will be done with the help of Pneumatic boring machine, 50 Kgs BFC will be placed in the bore to cover the earthing rod from all sides. BFC will be poured in Slurry form in properly mixed condition. The Earth pit cover Square 300x300x240 mm to be provided to cover the earth Pit and shall be made of reinforced FRP and should be capable of carrying the weight of 5 Tons. Make : U-PROTEC or equivalent in Ashlok earthings/JEF technology NOTE :- (a) Rates of boring 3 Mtr for earth electrode, GI strip 20x3 mm & 40 mm dia protection pipe upto 7.5 Mtr from earth electrode is deemed to be included in the quoted rate. (b) On testing, after, after completion, if the earth resistance <3 ohms is not obtained, earthing will be rejuvenated at no extra cost till the desired earth resistance is obtained. (c ) Test certificate from the OEM has to be produced by the contractorfor the material used in earthing
