Gantry together with 5 ton chain pulley bloc for extraction/lowering of pumping machinery along with allied works. The job includes P/F of 40 mm dia. Cast steel sluice valve - 01 no., 40 mm dia. cast steel NRV - 01 no. at delivery side, pipe wrench 24 mm and maintenance tool kit along with tool box. The complete job includes cost of the submersible pump sets, G.I. pipes, submersible cable, providing, fabrication/fitting charges of GI pipes with flanges/ nipple with flange & MS U-clamp, nuts/bolts, patching roll, rubber gaskets, lowering charges, all labour, carriage charges and taxes etc. Complete job including testing of submersible pump set after making all electrical connections of the submersible motor with the LT control panel at site. Design, fabrication, providing, installation, testing & commissioning of 50 Amps LT Control Panel 415 volts, AC- 3 phase, 50 Hz + 5% suitable for operation of submersible motor along with MUG-10/15 as standby. The panel shall be dust and vermin proof fabricated out of 14/16 SWG CR Sheet supported on M.S. angle job of suitable size with provision for fixing it on the ground with the help of foundation bolts. The panel should be sturdy enough for vibration free operation and should be equipped with suitable locking /sealing arrangements. The structure should be provided suitable entry and exit holes for incoming and outgoing cables. The panel should be given two coats of anti-rust primer and two coats of suitable / steel grey enamel paint. The panel should be equipped with following components / features: 1. Incoming feeder for 50 Amps panel: The panel should be fitted with an MCCB 100 Amps., 3 pole of L&T Havel’s or standard make only so as to break the power supply for rectification of the fault, 01 no. voltmeter, 01 no. voltage selector switch and a set of R-Y-B indicators at incoming side. 2. Outgoing feeder for 50 Amps LT control panel: The panel should be fitted with an Air break Star delta starter for operation of induction motor. The starter panel shall comprise of 03 nos. air break power contactors of 50 Amps, 50 Amps & 50 Amps. capacity of L&T only, (02 nos. for main and delta supply, 01 no. air break contactor for star operation of the motor), 01 no. voltmeter, 01 no. ammeter along with selector switches and a set of CTs and a set of R-Y-B indicators, 01 no. timer for change over supply of motor from star to delta, 02 nos. push buttons for start and stop operations of the motor and 1 no. MCB of suitable rating for protection of internal control wiring, a neat and clean internal control wiring should be made with flexible copper flexible PVC LT copper cable with proper thimbling at each end to complete the star delta circuit of outgoing supply. Protection device / Fault analyzer: A protection device / fault analyzer shall be fitted with the panel with capability to identify and trip off the motor on power failure and on appearance of electrical faults as mentioned below which may otherwise damage the induction motor 3..Protection Devices/Fault Analyzer :- The protection device /fault analyzer should provide protection against: i) Low voltage below 350 volts ii) High voltage above 440 volts iii) Single phasing iv) Reverse phasing v) Unbalanced phasing vi)Over loading vii)Dry running viii) Earth fault A bimetal overload relay of suitable range / set of fuses should be fitted within the starter as an extra protection to protect the motor in case of failure of fault analyzer with an isolation/bye pass switch to bye pass the fault analyzer. 4.Testing & commissioning: The job includes shifting of the panel to each of the above stated site, providing & fitting of 16 mm2 multi strand copper cable (Havel’s ,Polycab or standard make) 20 m in length for making electrical connections between the 200 amp. main switch and the MCCB of the LT control panel. The Job includes providing and fitting 3.5 core armoured al. cable 50 mm2 (Havel’s ,Polycab or standard make) from electric pole to 200 Ampere main switch approximately 50 meters in length The panel should be tested firstly on no load and then on full load with tripping of the starter in the panel on running of the submersible motor installed at respective station on all the tests as referred above to test the fault analyzer cum controller, MCCB, contactors and internal wiring of the panel, checking of any loose connections & their rectification thereof etc. The complete job includes cost of panel/ material, labour charges, transportation/ shifting charges up to site of work, including installation, testing and commissioning charges and taxes.
