gas insulated switchgear,
high voltage electrical switchgear
33Kv / 36Kv / 40.5Kv Indoor RMU Switchgear , Sf6 High Voltage Switchgear
NINGBO TIANAN (GROUP) CO., LTD.
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.
Each compartment is monitored individually & has its own pressure relief device.
The primary side components are hermetically enclosed, gas filled compartment and thus insensitive
to atmosphere, dirt &dust.
3. Space saving
Smaller foot prints All operations on the switchgear front.
4. Economically efficient
Reduced space & surface area requirement. Long service life Maintenance free Gas compartment.
