GIS Disconnector Switch
As the main components of the Gas Insulated switchgear , bear the main function, has the performance of dividing and closing the rated current, load current; closing and opening the circuit breaker, grounding, etc.
GIS Operating mechanisms for
Disconnector switch
GIS Operating mechanisms for Disconnector switch is the main components of GIS, it it impossible to remove the cable compartment covers with the earthing switch in open postion. It will then also be impossible to operate the load break/disconnector switch to open position before the cable compartment cover is mounted properly.
