RMU / Ring Main Unit

The ring main unit or RMU is an electrical device that combines a set of high-voltage switches. These switches are either placed into a steel cabinet or made into assembled interval-type ring network power supply units. The core part of a RMU is the load switch and the fuse. It has many advantages, such as simple structure, small volume, low price, safe power supplying, as well as improvable supply parameters and performance. It is widely used in the power distribution stations and box-type substations in the load centers like factories, urban residential areas, etc.
