Indoor 10kV MV GIS Ring Main Unit Switchgear , Gas - Insulated Safering Cabinet
General
XGN58(HXGT6A)-12/24 Switchgear(RMU) is a kind of composite
apparatus which seals all themain circuits switches in a metal
enclosure and uses SF6 gas as arc-extinguishing and insulation
medium. It is suitable for RMU and double radiation power supply in
12/24kV power supply circuit. The product is especially suitable
for industrial and commercial zones or rural area, which have
high-density power supply load and use cable feed network.
Meanwhile, the RMU has the advantages of safe operation, no weather
influence, easy installation, lttemaintenance and space saving,
which is suitable to be installed in box-type substation. TheRMU
can be flexibly combined by the extension of bus bars.
