Ring Main Unit (RMU)

Ring Main Unit (RMU) is a compact, enclosed, and sealed type of switchgear used for medium voltage power distribution. It is a complete switchgear in itself, meaning it includes the required switching devices, protection devices, and metering devices. RMUs are available in different voltage and current ratings, with both indoor and outdoor types available.

RMU consists of one incomer feeder and one or more outgoing feeders. The incomer feeder is either a Vacuum Circuit Breaker or an SF6 Circuit Breaker, with an associated Disconnect Switch and Earth Switch. This feeder is provided with a bushing for supply cable connection.

The outgoing feeder consists of Load Break Switches with an associated Disconnect Switch and Earth Switch, also with cable connection provisions. Switchgear specifications are customized according to customer requirements.
