GIS or Gas Insulated Switchgear | Electrical4U· SF 6 gas pressure for insulating purpose is generally kept below 2.5 bar whereas SF 6 gas pressure for interrupting purpose is ranged from 5 bar to 7 bar. As vacuum technology is not available for high voltage, so for GIS or gas insulated switchgear system above 72.5 KV, only SF 6 is used both for interruption medium and insulation.
