URING (RMU)
URING Series Complete SF6 Gas Insulated Metal Enclosed Modular and Compact Switchgears (RMU) with its increased functional properties and minimized dimensions can be used in today’s advanced MV secondary distribution systems.
The RMUs suitable to use in SCADA systems are operated with Puffer system (directing the SF6 gas directly on the arc). RMU offer a unique solution to the user with its remote opening closing property even without the motor provided that the mechanism is installed previously. The RMU offer smart solutions to the user due to their compact dimensions and increased safety properties in a metal or concrete kiosk type substation in the MV secondary distribution systems.
