RQRM6-12-24 series SF6 Gas-insulated metal-enclosed switchgear (GlS) is a new-model medium voltage ring switchgear developed by ROOQ Electric Group. The GIS is applicable to distribution devices of three-phase 50HZ and rated voltage of 12KV. It is widely used in industrial and civil cable ring nets and power supply terminals, especially applicable to the power systems of small size secondary distribution stations, on-off rooms, industrial and mining enterprises, urban communities, airports, rail way, tunnels, multi-storey buildings for power distribution.
