Supply, testing, commissioning and handing over of 1 No 160KVA Diesel Generator set with standard control panel of 0.8P.F.Three phase 415/ 420 Volts, 50C/S 1500 RPM as detailed below. 1. ENGINE: Water cooled diesel engine suitable for Generator application with a shaft output of 310 BHP at 1500 RPM under NTP conditions as per BSS 5514/ IS 10000. The Engine shall comprise the following standard scope of supply. (Make Kirloskar / Cummins / Ashok Leyland / Greaves / Equivalent) 1. Dry type Air cleaner 2. Expansion bellow 3. Radiator, Radiator fan and mounting 4. Air to air charge cooler 5. Exhaust Gas turbo charger 6. Lube oil cooler and Lube oil filter 7. Fuel filter (pre and Micro) 8. In-line Mono-block fuel injection pump with governor and fuelfeed pump 9. Electronic governor 10. 24V Battery charging alternator 11. 24V Volt electric starter motor 12. Engine test Certificate 13. Residential Muffler 14. Fly wheel with starter ring. Engine Instrument panel mounted Engine control panel consisting of ON/OFF/START Key Lube oil pressure gauge, Oil temperature gauge, high water temperature gauge and electronic hour meter and RPM indicator.

SAFETY SYSTEM OF ENGINE The Engine shall trip for the following conditions with visual alarm device. 1) Low lubricating Oil pressure 2) High Water temperature 3) Vee-belt failure and over speed 4) Low battery indication. The Engine should be capable of providing 10% over load for one hour for every 11 hours continuous running at full load. 2.ALTERNATOR: Alternator capacity of 160KVA /128KW, AC3 phase,50HZ,415 volts,0.8 P.F.4 wire self excited, self regulated designed to run at 1500 RPM under NTP conditions conforming to BS 5000/IS 13364 (part-II) 1992 to be coupled directly to the Diesel Engine and test Certificate (Make: Kirloskar /Cummins/Ashok Leyland /Greaves/Equivalent.) 3. ACOUSTIC ENCLOSURE: Acoustic enclosure shall be powder coated and fabricated of 16 SWG CRCA MS sheet. The silent canopy shall be of nut bolt type construction. Critical processes of punching are done on CNC Machine to maintain dimensional accuracy of hole within 0.1mm Power coating done after seven – tank surface preparation process of sheet metal. Canopy panel and doors shall have inside lining of FIRE RETARDANT 64 Kg /m density mineral wool of 100mm thickness As acoustic material. Four hinged doors shall be provided to canopy. The average sound level at 1Mt. distance shall be less than 75 DBA average or as per CPCB norm Surface treatment.

4. Painting: The enclosure surface shall be suitably treated for degreasing de -rusting and posphating. The canopies are passed through seven-tank treatment throughly Additional features of canopies: - Canopy fabricated on CNC machines with dimensional accuracy of 0.1mm so as to increase its durability. Special designed supporting rips/ structures are used in canopies so as to give studiness and to reduce the vibrations of the DG sets if any World class Cooling package: Canopies shall have cooling package for which it can also perform at 45 deg c / ambient temperature No grouting required on the ground, only a level surface capable of with standing the DG weight. Lifting hooks shall be provided for the acoustic enclosure, which should be unloaded independently of the DG set. The Gen set frame shall also be provided with hooks for unloading, Temperature rise inside the canopy: Canopies shall be designed so as to maintain the temperature difference between ambient and air inlet at cleaner within the enclosure well within 5-7 deg centigrade. 5. BASE FRAME: Base frame should be fabricated in sheet metal. The base frame is rugged in construction and designed for mounting engine and brush less alternator closely coupled, with cross members mounted on AVM. The base frame shall be provision for mounting of acoustic enclosure on it. The supply of Gen set includes loading, unloading and transportation charges.

6. FUEL TANK : 380 liters . Removable fuel tank shall be fabricated out of 14 SWG CRCA MS sheet and is part of base frame. It is duly painted and fitted with inlet and outlet connection and mechanical fuel gauge. Fuel tank can be easily removed for clearing or any maintenance. 7. BATTERY: 2Nos 12V 180 AHR Battery. (SR)
