  • Sulfur hexafluoride - Wikipedia

    Sulfur hexafluoride or sulphur hexafluoride, is an extremely potent and persistent greenhouse gas that is primarily utilized as an 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. It is a hypervalent molecule. Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density of

    Breakers that use carbon dioxide as the insulating and arc extinguishing medium work on the same principles as a sulfur hexafluoride (SF 6) breaker. Because SF 6 is a greenhouse gas more potent than CO 2 , by switching from SF 6 to CO 2 it is possible to reduce the greenhouse gas emissions by 10 tons during the product lifecycle.
