Supply, installation, testing & commissioning of 11 KV, 630A, 21kA/3sec, Outdoor type, both sides extensible, Internal arc 21kA for 1 Sec for Tank, floor mounted with internal copper bus bars, SF6 Insulated, completely Motorised, 6 Way RMU consisting of 2 Nos LBS as Incomer & 4 Nos 630A VCBs as Outgoing with SACADA compatable Overload and eart fault protection Relay (Ashidha / CSPDR) with air insulated Metering module (MFM for VCB Feeders). All live parts, bus bars, LBSs connections of RMU shall be enclosed in one SF6 tank to avoid multiple interconnections. SF6 Tank shall be sealed for life robotically welded non magnetic and non ferrite stainless steel Grade 304 of minimum 2.5 mm thick having IP67 degree of protection filled with SF6 gas as insulation with leakage rate less than 0.1% per year tested as per IEC 62271-200.

Manual welding or hermetic sealing of tank shall be not be accepted. The unit shall have front cable entry for ease of installation and shall have site replaceable bushings for ease of troubleshooting during breakdown. RMU should be complete with all accessories such as Terminal boots, VPIS, cable supports, all front cable terminations, mechanical indications for Load break switch ON/OFF, Manometer as per with IEC standards. Altitude of installation up to 1000m as per IEC 60120. Bushings bolted type top mounted outside the tank for connection of external bus bar. Also, the outer enclosure shall cover the full length of the switchgear,to ensure IP3X+IP54 protection for cable boxes. The unit shall be internal arc proof 21kA for 1 se with AFLR clasification.,tested and totally safe for human beings. The gas release & personnel safety from internal arc shall not depend on plinth design. The release of gas to be from the top of the unit, so that, even if the person is operating the unit, opening the cover, & there are personnels near the sides of the RMU/plinth, top release will ensure their safety. The hot gas release, in case of an internal arc, in no case should be from any side or bottom of the unit, as the same is unsafe for the operating personnel/pedestrian or general public. Bidder shall provide type test report to prove compliance to the Internal Arc fault IAC-AFLR as per IEC 62271-200. Internal arc testing shall be done with enclosure door in open condition, with switching devices in operation mode as per specified standard. complete all as directed of make : BHEL / ABB / SCHNEDIER / SIEMENS / ANDREW YULE.
