Grid switchgear uses SF6, the world's most potent ...· The switchgear technology that has been growing most in popularity and is considered a 'premium' technology is called gas insulated switchgear (GIS). As the name implies, this technology contains a gas which happens to be the world's strongest greenhouse gas; Sulphur Hexafluoride (SF6) .
SF6 (Sulfur Hexafluoride) Recovery | Hudson Technologies is widely used as an insulating and arc quenching gas in medium and high voltage transformers. As equipment ages, it is being repaired or replaced with more efficient equipment which typically uses 1/3 the quantity of SF6. This creates a need to recover the SF6 for recycling or disposal.
Gas-insulated medium-voltage switchgear· PDF fileReliable protection of the high-voltage part of our gas-insulated medium- voltage switchgear is provided by a hermetically sealed primary enclosure and by insulation consisting of inert sulfur hexafluoride. This makes the switchgear resistant to environmental effects such as humidity, saline air and dust, but also prevents ingress of small animals.

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.
