Complete job includes cost of material like sluice valve and reflex valve, bends along with other fitting materials. Painting: Scratching of rusted portion by emery papers on both newly laid suction and delivery pipes and making an even surface for painting of the pumping equipment. Painting of all the suction, delivery pipes with one coat of red oxide and then painting of all the pumping equipment with two coats of synthetic enamel. i.e. suction delivery, sluice valves, reflux valve etc. Job including cost of material and labour charges. (Complete job). LT Control Panel: Design, fabrication, installation, testing and commissioning of dry starter cum LT panel suitable for operation of 180 HP induction motor at CPS Muthi Phase II. The panel should be dust and vermin proof fabricated out of 14/16 SWG CR sheet supported on MS angle of suitable size and provision for fixing it on ground with the help of anchoring 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 steel grey enamel paint. The panel should be equipped with following components / features: - 1. Incoming Panel Box: - The incoming panel box is fitted with MCCB of suitable capacity for OL, SC, EF protection having display with ON / OFF, trip indicating light, digital voltmeter, and digital ammeter, control fuses etc. of approved make. Star Delta Starter: - The panel should be fitted with 1 no. dry star delta starter for 180 HP motor. Starter should comprise of 3 No. air break contactors of reputed ISI mark make of suitable capacity. i.e., 2 Nos. for main and delta supply and 1 No. for star operation. Starter should be equipped with 1 no. timer for change over the supply of motor from star to delta, 2 nos. push buttons for start and stop operation of motor, 1 No. indicator, 1 No. MCB 6 Amps. for the protection of internal control wiring, a neat and clean internal control wiring should be made with flexible copper cables to complete the star delta circuit of outgoing supply. Protection device / fault analyzer: Protections device / fault analyzer shall be fitted with the panel with capability to protect the individual motor by isolating the power supply of motor by de energizing the starter / panel from following electro mechanical faults which may otherwise damage the motor windings: a) Voltage related fault: Single phasing, under voltage, over voltage, unbalance voltage. b) Current related fault: Over current / load, dry running, unbalance current / load, earth leakage, short circuiting. c) Mechanical fault: Locked rotor, broken shaft. d) Display line current of RYB phase and also line voltage of RY and YB phase. Display and record trip counts and indicate trip status for over load, under load, single phase, unbalance, earth fault, over voltage, under voltage respectively. Analyze, display & records No. of operation & duration of motor running. Bimetal over load relay: A bimetal over load relay each of suitable range should be fitted with the individual starter as an extra protection to protect the motor in case of failure of fault analyzer. With an isolation/bye pass switch to by pass the fault analyzer. In addition to this the starter should be connected with main incoming M.C.C.B with bus bar / copper flexible cable arrangement of adequate current carrying capacity. All other components i.e., meters, indicators, push buttons, protection relays, operating coils of contactors etc. should be connected with 1.5 Sq mm flexible copper cable to complete the circuit for operating the motors.
