MGS Series 12kv 13.8KV 24KV 33KV 36KV Medium Voltage Metal Enclosed SF6 Insulated Ring Main Unit RMU Switchgear
High Voltage Cabinet SF6 Ring Main Unit Switchgear Panels
MGS series Ring Main Unit is an extensible,SF6 insulated
switchgear.It can be supplied in 10 different configurations suitable for most witching applications in 12/24/36 kV distribution networks,they represent a complete solution for 12/24/36 kV secondary distribution networks.It has same identical user interfaces with ABB.
All its HV live parts are contained in an air-tight gas tank,which is made from stainless steel of 3mm.The whole switching assembly is SF6
insulated,and free from any external influence,ensuring it great reliability of service and maintenance free.
MGS series Ring Main unit offers a choice of either switch-fuse
combination or circuit-breaker with relay for protection of the transformer.
MGS can be supplied with an integrated remote control and monitoring unit.
