In an electrical power distribution system, a ring main unit (RMU) is a factory assembled, metal enclosed set of switchgear used at the load connection points of a ring-type distribution network.
The ring circuit cable starts at the consumer unit (fusebox]), visits each socket in turn, and then returns to the consumer unit. The 2 cable ends at the CU are connected together in all modern rings, and supplied by one fuse or MCB. Ring circuits are widely used to supply sockets for 13A plugs.
The oil insulated ring main units are commonly seen in mining and oil field applications. Gas insulated ring main units use SF6 S F 6 gas as the insulating medium and are used in low to medium voltage distribution networks to provide uninterrupted power supply and protect the electrical equipment.
Indoor as well as outdoor types of Ring Main Units are available. Ring Main Unit comprises of one incomer feeder and one or more outgoing feeder. The incomer feeder is either Vacuum Circuit Breaker or SF6 Circuit Breaker with associated Disconnect Switch and Earth Switch.
