Sulfur hexafluoride - Wikipedia hexafluoride (SF 6) or sulphur hexafluoride (British spelling), is an extremely potent and persistent man-made greenhouse gas that is primarily utilized as an excellent electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom.

Next level automation and power transmission – from ABB 170 kV GIS systems, ABB has developed a solution which replaces traditional sulfur hexafluoride gas (SF6) with an innovative insulating gas mixture. The insulating properties of the new ABB gas mixture are similar to those of SF6, but much more environmentally sound. Emissions over the service life of the equipment are reduced by 50 percent.
