Designing / fabrication / Installation / Testing and commissioning of Automatic LT control panel of 415 Volts, AC III-phase 75 HP and 35 HP Capacity at pumping station KundManjhari Base under WSS KundManjhari (NRDWP)

Amount

Designing /fabrication/ Installation/ Testing and Commissioning of Automatic LT control Panel of 415 volts, AC 3Phase 75 HP capacity induction motar and 75 HP Submercible motor installed at base Kund Manjhari.The panel should be rust and vermin proof. fabricated out of 16 SWG CR sheet supported on MS angle of suitable size and provision for fixing it on panel board. The panel should be sturdy enough for vibration free operation and should be equipped with suitable locking/sealing arrangement. The structure should be provided with 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 enamel paint. It should be equipped with following components/features:-MCCB:-The panel should be fitted with MCCB 160 Amp, 415 V, 35KA capacity to protect the panel in case of short circuit. VOLTMETER:- The panel should be fitted with digital voltmeter to show the voltage between phase to phase and between phase to neutral. AMPERE METER:- The panel should be fitted with digital Ampere meter CT operated to show the ampere between each phase. PHASE INDICATOR:-The panel should be fitted with phase indicator R/Y/B to indicate the phase. STAR-DELTA STARTER:-The panel should be fitted with 02No contactors 140Amp (L&T Make/ reputed Make) for main and Delta and 02 No contactors 185 2 nos, 110 one no and 110 2 nos, 70 one no. for star operation, 1No timers for change over the supply of motor from star to Delta,2No push buttons for start and stop operation of motor,1No thermal relay range of suitable capacity fitted with main contactors. All control wiring should be neat and clean with flexible copper cable to complete the star Delta circuit of outgoing supply and wiring should be protected with fuse. The system should provide protection against:- • Low Voltage below 350 V. • High Voltage above 450 V. • Single phase • Reverse Phasing • Unbalance phasing • Dry running • Over loading Testing and commissioning of control panel by making/connecting to incoming terminals and outgoing terminal of control panel. Testing the performance of the panel on no load and on full load. Complete job includes cost of material, labour charges, carriage charges& fitment charges at the site of work.

P/F of Al.Cable 250mm Sq. 50 mtrs in length H/D to be layed for making connection from LT pole to main switch to volt stabilizer for all three phases..The complete job includes cost of material and labour charges and hire charges of vehicle,charges skilled/unskilled and testing and commissioning of HCP set on full load.Testing and commissioning of HCP set after checking of alignment of pump & motor, and voltage stabilizer checking all the electrical connections with megger, tightening of loose connections if any, plugging of leakage of joints by welding & tightening of nuts & bolts etc.
