SF6 gas insulated ring main uint(RMU), 12kV,24kV,36kV available. switchgear.GIS
SF6 gas insulated ring main unit(RMU):
Safe ring/plus RMR type SF6 gas insulated ring main unit is integrating with SF6 infill cabinet which gather with LBS, Fuse, ES, DS, etc.
By the perfect integration of stationary type and flexible expansion, RMR type
SF6 gas-insulating compact close metal switchgear(Ring main unit) with the adoption of the modular
design, is suitable for end-user or network node, meanwhile meets the requirement of
all kinds of switching substations?cabinet-type transformer substations and cable
branch cabinets. It characters on its compact structure, safety and reliability,longevity
and maintenance free.
This product is in conformity with the standards of IEC60420,GB/T11022,GB3804,GB3906
