Repairs to electro mechanical components for 2 x 150 HP pump-motors units along with other allied works at LIS Kot-II.

Repair of LT control Panel for 2×150Hp Motors installed at LIS KOT-II by disconnecting the incoming and outgoing cables of LT panel. P/F of new 400 Amp rated main incomer MCCB (1 No.) and 320/300 Amp MCCB (1 No.) for the primary 150 HP pump motor unit in place of damaged/worn out ones. These MCCBs should be provided with spreader terminals of requisite specifications along with P/f of new bus bars for making the circuit connections with these spreader terminals. The MCCBs should have a minimum of 36KA breaking capacity at 415volts-50 hertz. The job further involves provide and fitting of protection relays (for each 150 HP motor) having under & over voltage protection, phase failure/single phase protection and current/thermal overload protection as per motor characteristics by way of P/F of Shunt modules along with the aforementioned MCCBs of requisite specifications, CT coils, circuit wirings & other electronic components within the panel to give the desired aforementioned protections to each 150 HP (2 No.) motor pump units. The job also involves replacing the old damaged/ worn out circuit wiring with new circuit wirings. Servicing of panel by cleaning the contact with suitable chemicals to make it spark free. The job also includes replacement of damaged voltmeter, ammeter and 3 phase light indicators for the LT control panel and voltage stabilizer. The job further involves provide and fitting of 600/630 ampere HRC fuse based main switch of reputed make in place of worn out existing one. Complete job includes rebate on account of old damaged/worm out parts/components, cost of material and labor charges for skilled and semi-skilled labor, hire charges of tools and tackles required at site for execution of job (Complete job).

Provide and fitting of 300 mm² single core XLPE insulated ST2 Type outer sheathed Aluminium cable (30 m approx.) of reputed make as per IS 7098 (Part 1) 1988 with upto date amendments, in place of damaged burnt/worn out existing cables laid between the main switch to voltage stabilizer and between voltage stabilizer to control panel by way of disconnecting LT supply from transformer side after removing removal of rusted thimbles along with cable from main switch output and then removing the other end from voltage stabilizer by cutting the rusted thimbles with cutter. Similarly removing the old wire from the voltage stabilizer to the control panel and replacing them with new above mentioned single core wire. The job further includes P/F of new thimbles on new single core Aluminium cable after preparing all the sixteen ends for connection from Voltage stabilizer to main switch and from Voltage stabilizer to LT control panel using appropriate tools and tackles and securing and tightening properly at suitable ends using cotton tape etc. testing on no load for checking the continuity of phases and the testing on full load. The job includes rebate on account of old damaged/worn out parts/components, cost of material, carriage, skilled and semi-skilled labour, hire charges of tools and tackles required at site for execution of job (Complete job).
