General information on SF₆ / Sulfur hexafluoride

Under normal conditions, sulfur hexafluoride (SF₆) is a colorless and odorless, non-toxic and non-flammable gas which, like nitrogen and CF₄, behaves in an extremely inert manner. Sulfur hexafluoride is used as an insulating gas in medium- and high-voltage technology, for example in gas-insulated switchgear (GIS) with high-voltage switches and in gas-insulated pipelines (GIL) in completely enclosed systems with operating voltages from 6 kV to 800 kV. SF6 also serves as an extinguishing gas to interrupt the switching arc in circuit breakers. Due to its high global warming potential (GWP=23500), this gas may only be used under strict conditions.
