Gas Detection Cameras | FLIR Industrial | FLIR Systems FLIR GF306 optical gas imaging camera visualizes sulfur hexafluoride (SF6) and other gas emissions without the need to shut down operations. SF6 is used in the electric power industry as an insulator and quenching medium for gas-insulated substations and circuit breakers.
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.
