Ring Main Unit Optical Cable

Ring main units (RMU) are widely used in industry and for distribution systems. RMUs operate independently, which means that it is possible to earth an incoming supply cable while it is still energised from the other end or operate a switch and liven a cable onto an earthed. Future-proof due to SF6-fre e Designed on the basis of specific customer enquiries for a complete replacement for gas-insulated switchgear systems, the new NATUS Type NES-F-RK ring cable switchgear system has been developed using airtight technology for operating voltages of up to 12 kV. The precise arrangement and configuration of components always depend on the particular application and loading. In an electric 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.
