hv insulating gas High pressure Cost-effective

SF6 gas pressure for the insulating use is preserved below 2.5 bars while SF6 gas pressure for interrupting purpose is ranged from five to seven bar. Also, as vacuum technology isn't accessible for high voltage, so for C GIS system above 72.5 KV, only SF6 is utilized both for insulation and interruption medium.
