SF6 Gas Insulated Substation. The SF6 gas insulated substation (GIS) is assembled by several SF6 gas insulated switchgear configurations in an outdoor enclosure which could reach IP54 protection grade. With the advantage of SF6 gas insulating ability (the interrupting arcs capability is 100 times more than air), gas insulated substation could

This was also the method used by the discoverers Henri Moissan and Paul Lebeau in 1901. Some other sulfur fluorides are cogenerated, but these are removed by heating the mixture to disproportionate any S2F10 (which is highly toxic) and then scrubbing the product with NaOH to destroy remaining SF4.
