RMU Switchgear , Sf6 High Voltage Switchgear With 33Kv / 36Kv / 40.5Kv
General:
The GIS is suitable for power plant, substation, combined substation and electric power system, which is three phase indoor AC single busbar and sectioning single busbar with 50Hz, 35kV rated voltage, used to control, accept and distribute electric power.
Functional design:
Reliable:Each compartment is monitored individually & has its own pressure relief device.
Safety:The primary side components are hermetically enclosed, gas filled compartment and thus insensitive:to atmosphere, dirt &dust.
Space saving:Smaller foot prints All operations on the switchgear front.
Economically efficient:Reduced space & surface area requirement. Long service life Maintenance free Gas compartment.
