WORK OF PROVIDING AND INSTALLATION OF CHEMICAL EARTHING UNDER EUDD V NOIDA

Amount

PROVIDING AND INSTALLATION OF CHEMICAL EARTHING FOR DISTRIBUTION AND POWER TRANSFORMERS (WITH ALL MATERIAL AND LABOUR) AT VARIOUS SITE AFTER INSTALLATION RESISTANCE SHOULD BE LESS THAN ONE OHM. AS PER FOLLOWING :- Note :- The all material and labour shall be provided by the contractor with 12 month guarantee for resistance value less than one OHM and should be checked 06 months after proper installation.

Providing of earth elctrode for chemical earthing Pipe in pipe type proper hot deep galvanization dia 50 mm length 3 mtr - 32mm x 6mm terminal connection hole dia 8mm The cavity between the pipe & pipe is filled with conductive mixture - for hermetically filling inside the cavity i.e. between secondary conductor & primary conductor, crystalline compound is to be injected in the electrode assembly. It is a combination of high conductivity metal alloys, copper & aluminum power, conductive carbon / cement and bonding material etc the electrode should be sealed from both the ends. The outer pipe of the elctrode should be galavanized the characteristics of this compound is highly cnductive, non magnetic & non corrosive in G.I. Including providing of backfill compound each elctrode should be supplied with bags of 25 kg x 2 bfc compound (ground resistance enhancement powder 50 kgs each CPRI tested for different capacity distribution t/f installed at various 11/0.4 KV L.T. Substation.

Providing and fixing of GI strip of size 32 mm x 6 mm suitable for different capacity distribution t/f installed at various 11/0.4 KV L.T. Substation.
