gaz sf6 Gas Insulated Switchgear(GIS) Manufacturers and Suppliers

gaz sf6 gas pressure for the insulating use is preserved below 2.5 bars while sf 6 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 insulating gas is utilized both for insulation and interruption medium.
