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.
SF6 Sensors | Gas Insulated Switchgear (GIS) | smartGAS 6 sensors for gas-insulated switchgears (GIS) . The main area of application for the non-flammable gas sulphur hexafluoride (SF 6) is insulation of electrical high-voltage switchgears, transformers and cables.Although sulphur hexafluoride is non-toxic and non-flammable, its global warming potential is about 24,000 times higher than carbon dioxide (GWP=23,900).
