Apr 28, 2008 · Sulfr hexafluoride is generally used in this gas-insulated switchgear (GIS). Because it is so important to control greenhouse gas emissions, any plant containing insulating gas should be equipped with monitoring systems to warn of leaks. Regular inspection is necessary, typically twice a year, which inevitably adds to the total operating costs of the switchgear.

Sulfr hexafluoride: Does its Impact Outweigh its Benefits? | TD World

Sulfr hexafluoride gas has been used extensively since the mid 1950s to replace oil as an insulator in electric equipment, and more recently in gas insulated switchgear (GIS) and gas insulated lines (GIL). It is also used in medium voltage switchgear primarily outside the United States and extensively worldwide in low switching capacity gear.

Switchgear - Wikipedia

A 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.
