Amount

Providing of machinery and equipment spares/parts (Andrew Yule make/ equivalent make) for HT motor feeder (800 Amp, 6.6 KV ,25 KA) panel of unit no 3 installed at Tawi Pump House Jammu by way of Providing and fitting of Andrew Yule /Equivalent make new spares Such as Shunt trip coil 110 V DC-01 No, closing coil-110 V DC 01 no, spring charging Motor -01 No., Breaker axillary switch-01 No, Axillary contactor 110 V AC -01 no and bottle Vacuum interrupter(01 Nos.) 800 amp, 6.6 kV. P/F new wire maintaining proper color code and using ferrule for proper identification, checking working of charging and release mechanism. Inserting vacuum interrupter in the compartment. P/Fitting of new master tripping relay in panel. The job include drawing out VCB trolly from the chamber, extracting old parts such as Shunt trip coil 110 V DC, closing coil-110 V DC , spring charging Motor , Breaker axillary switch-, Axillary contactor 110 V AC and bottle Vacuum interrupter(01 Nos.) 800 amp, 6.6 kV. of one phase, cleaning chamber from inside using air blower ,cleaning all the terminals using CRC spray, applying Lubricants to mechanical linkages for smooth operation, resetting/ adjustment of vacuum interrupter for proper gap between fixed and moving contacts, checking continuity of all the phases also checking IR value between fixed and moving contact of all the phases , across phases and between phase and earth using meggar . Tightening all the terminals properly, checking all control wiring and replacing if any wire seems worn out/ electrical stressed. Complete job includes cost of material, fitting and testing charges
