Providing and fabrication of Column Pipes 15 no (3 mtrs length approx) out of 100 mm dia G.I. pipe of Medium class B, beveling of ends on heavy duty lathe machine and providing and fitting of flanges by welding to both ends of column pipes in proper alignment after making cuts for passing of submersible cable. Painting of all the column pipes. Fabrication, providing and fitting of 01 no U shaped tie rod and pipe clamp of suitable size as per pump size made out of MS Flat to be fitted with the submersible pump with heavyduty nut and bolt welded on both sides of the clamp. Job also includes fabrication of 01 no graded expander/reducer of required size threaded at one end and flanged at other end. Fitting of reducer/expander with column pipe at one end with flanged joint and with the discharge outlet of the submersible pump at other end. Lowering of the submersible pump set 10000 GPH x 60 m head with the help of heavy duty chain pulley block of 5 ton capacity along with flanged column pipes one by one after tightening of each with new nuts and bolts and rubber gaskets of the flanged joints to ensure leak proof connections. Making of all the incoming and outgoing electrical connections. Providing &Fitting of clamp (100mm dia.), 100mm dia delivery pipe along with 100 mm dia bend horizontally for water discharge to channels. The job includes cost of material &labour charges, transportation, tool and tackles required for the execution of complete job. Designing, fabrication, installation, testing and commissioning of LT Control cum protection panel 415 volts, AC 3 phase, 50 HZ suitable for submersible motor installed at Tube well Dug . The panel shall be enclosed cabin, dust free and vermin proof fabricated out of suitable SWG CR sheet Supported on MS angle. There should be a provision in the panel for fixing it on the ground / wall as per site requirement. The panel should be given two coats of anti rust primer followed by enamel paint. The panel must have equipped with following component/feature .1 )M.C.C.B. The panel should be fitted with and M.C.C.B. 100 Amp 01 no, voltage meter 01 no, ammeter 01 no along with a set of CTs, 1no Volt Selector Switch .and 1no Ampere Selector Switch and a set of RYB indicators at incoming side. 2 ) Star Delta Starter :The panel should be fitted with a fully automatic star delta starter comprises of 3no air break contactor of suitable capacity MNX (50-50-50 AMP, 2 no for main and delta supply ,1no air break contactor for star operation ) 1 no timer for change over the supply of motor from star to delta ,2 no push button for start and stop operation of motor ,3 no indicators for status of starter i.e. running, tripped, bypassed/inline of protection system, 1 no MCB 2 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 circuit outgoing supply . 3 )Protection device/Fault Analyzer: The panel should be fitted with the devices to protect the motor by isolating the power supply of motor by de-energizing the starter/panel form following fault which may otherwise damage the motor winding a) Voltage Related Fault: Single phasing, under voltage, Overvoltage, unbalanced voltage/reverse phasing. b) Current Related Fault: Over current/ load, dry running, unbalanced current/ load earth leakage short circuiting. c) Mechanical Fault: Locked rotor, broken shaft. 4) Bi-Metal Overload Relay: A bimetal overload relay of suitable range should be fitted within the panel as an extra safety to protect the motor in case of failure of fault analyzer with an isolation/bye pass switch to bye pass the faulty analyzer. Installation: In addition to this the panel cum star delta starter should be properly installed at Tubewell station on floor/wall mounting as per site provision with provision for foundation bolts in ground or wall fasteners in case of wall mounting. Providing and fitting of 200 Amps main switch and 3.5 core aluminum armoured cable, 35 Sq. mm from transformer to main switch of suitable length. The MCCB should be connected with the main outgoing of voltage stabilizer after necessary thimbling of the cable ends. The starter should be connected with main incomer MCCB with flexible cable of suitable current carrying capacity. The cable should be fitted with the help of insulators into the panel firmly to withstand any short circuit stresses. All other components i.e. meters, indicators etc should be connected with flexible copper cable to complete the circuit for operation of the motor. All the internal wiring should be neat and clean. Complete job includes cost of material, labour charges and transportation of panel from workshop to site of work including testing/setting of protection panel at different loads
