Tender For Supply Installation Testing and Commissioning of Silent Type Dg Set Of Capacity 400 Kva At Varunalaya Phase-Ii Djb Hq Jhandewalan
Name of Work:- SITC of Silent Type DG Set of capacity 400 KVA at Varunalaya Phase-II DJB HQ Jhandewalan
Sl. No.
Item Description
1
SITC of 400 KVA Sound Attenuated DG Set CPCB IV+ compliance comprising of engine coupled to 415 V 3 Phase alternator mounted on a common suitable M S Channel duly coupled and aligned base frame along with other accessories i.e Control Panel, inbuilt Fuel Tank, Batteries with leads. Insulation: A layer of rock wool/ mineral wool is provided on all the sides of the Acoustic Enclosure, to contain the insulating material in sheet framework, specially made for the purpose. Doors: Suitable doors are provided to facilitate easy access & maintenance of the engine. Locking Arrangement Heavy-duty brass locks are fixed to provide air tight locking of the doors. Packing Suitable size of rubber packing, Suitable packing is also provided at all such joints where any two metal parts are bolted to avoid entry of dust / water. Ventilation: A careful study of the air requirement of the Diesel Engine (as per manufacturer’s recommendation) is kept in view to facilitate smooth running of the machine within specified parameters. Lighting: Suitable lighting arrangement is provided inside the enclosure to help easy maintenance of the Diesel Generator. Exhaust Extension: The exhaust gas is taken out through the roof of enclosure with the help of flexible connector & M.S. Pipe. The inside portion of M.S. Pipe is cladded with glass wool & aluminium sheet to avoid any heat dissipation inside the enclosure. Specially designed Residential silencer is mounted on roof tops of enclosure / any other convenient place. The exhaust gas can be further extended to any other convenient location with the help of M.S. Pipe. Painting: The Acoustic Enclosure is painted of polyurethane paint for making it suitable for installation in open areas.Trunking: Suitable trunking is provided in the enclosure for routing of cable with proper glands. Control Panel: If desired, the control panel for D.G. Set can be mounted inside the Acoustic Enclosure facing a glass window for each access. In such case the panel is required to be fabricated as per space availability inside the enclosure. Batteries: At your option batteries can be kept inside / outside the enclosure. If the batteries are required to be kept outside the enclosure, a separate battery stand is provided for easy maintenance and protection from weather conditions. Diesel Tank: For easy filling & monitoring, it is recommended that the Diesel Tank should be kept outside the Acoustic Enclosure. In such case suitable openings are provided in the Acoustic Enclosure for fuel piping. If you require the fuel tank to be fit inside the enclosure, a compromise on the capacity of the fuel tank is desired.Alternator: General Alternator and accessories shall include, but not limited to generator, excitation system, automatic voltage regulator, generator control panel and relay panels. Alternator shall be self excited ventilated with drip proof open screen protected construction. Alternator shall have minimum reactance and low voltage waveform distortion. The line and neutral end of each phase winding of the Generator shall be brought out on six suitably located terminals. Contractor shall provide suitable clamping arrangement for connecting cable to the machine terminals. The terminals shall be suitably enclosed to prevent short circuits by rodents, etc. Excitation System: The excitation system shall have brushless type rotating field or static exciter with rectifier. The response ratio of the excitation system shall be not less than 0.50. The excitation system shall be so designed and or protected, that harmful over voltage cannot occur at the main exciter due to combined effect of maximum exciter field current and machine over speed. Voltage Regulator: (a). Continuous acting, non-dead-band type static automatic voltage regulators with accessories mounted in a suitable panel shall be provided for the generator. The automatic voltage regulator shall be capable of working over the whole load and voltage range of the generator. (b). The voltage regulator shall be of continuously acting, high response, static type and shall be complete with the cross current compensation preferably of static type. The regulator shall be supplied complete with voltage setting device, all accessories and other contacts. (c). AVR shall control generator voltage under steady state load conditions and over the whole of the operating range of exciter to within 1.5% of rated voltage. Optimised fuel consumtion with common rail electronic injection to ensure minimum fuel consumption during operation in full and no-load condition.Best in class proven technology for meeting stringent emission norms. Along with this the following works are also included as under:-1. Dismantling of old existing DG set by removing electric connection and remove the common base frame by cutting old nut bolt with the help of gas cutter and manual labour/ Crane, Heavy labour and demolish the RCC foundation by pneumatic hammer and shift the old DG set as the required place for making the space for New DG Set 2. Any Major or Minor civil works like DG Set foundation, fixing of DG Set etc., cable trench etc 3. DG Set unloading, shifting and placement & Freight Charges 4. All Mechanical and electrical works including earthing other allied works and erection of panels.Complete Supply, Installation, Testing and Commissioning work is in firm scope.
