Design, Supply, Erection, Testing and Commissioning of 11 KV, 630A, STC 21KA for 3sec, SF6 insulated, Manual, Outdoor, Non-extensible RMU , type tested in line with latest IEC standards. The RMU shall be suitable for operations at a height up to 1000 meters above sea level and at 40 degree ambient temperature without any derating. The switchgear and busbar shall all be contained in a stainless steel enclosure filled with SF6 at 0.3 bar (300 hPa) relative pressure. The RMU tank shall provide full insulation, making the switchgear insensitive to the environment with degrees of protection of IP67 . The switchgear operating mechanism shall have an IP2X protection and cable chamber shall have IP3X. Accidental overpressure due to an internal arc is limited by the opening of the safety valve, at the bottom of the metal enclosure, away from the operator. An operator situated in front, lateral (A-FLR 21kA – 1sec, downwards exhaust for tank and 0.2sec for cable compartment and 0.2sec. for breaker) of the RMU switchboard during an internal fault will not be exposed to the effects of arcing. Internal Arc Type Test Report for IAC AFL R21 kA for 1 sec for both tank & cable box should have been for minimum 3 way / 3 Function RMU, min. 40 nos. of dead short circuit operation at full load. Plug in type of extensibility must be provided and coupling busbar should not be exposed to air to avoid oxidation of busbars. Extension of cubicle should only require 450mm to handle and the gap between the coupled RMU’s must be within 10mm. All operations shall be from front of the RMU, including access to cable bushings. Cable bushings along the sides or the rear of the RMU are not acceptable.further manufacturer should ensure that their engineer should be at customer site for the supervision of commissioning of RMU.
