HV MV sf6 gas filled instrument - schallmarkus.de gas-insulated switchgear main insulation gas used in high and medium voltage switchgear is SF6 gas which has several important features. However, SF6 is a known greenhouse gas and while leakage rates are very low its lifecycle management requires careful handling for utility and industrial users and comes with some associated costs, particularly when decommissioning aging ...
Switchgear - Wikipedia switchgear may be a simple open-air isolator switch or it may be insulated by some other substance. An effective although more costly form of switchgear is the gas-insulated switchgear (GIS), where the conductors and contacts are insulated by pressurized sulfur hexafluoride gas (SF 6). Other common types are oil or vacuum insulated switchgear.
