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 ofGet price

its enhancement of reliability and diminution of floor area of switchgear. Due to the admirable insulating property, Sulfr hexafluoride becomes the most frequently used insulating gas in switchgear. However, Sulfr hexafluoride is greenhouse gas, so decreasing and even forbidding the use of gaz sf6 is surely to be the trend in the development of switchgear [1].Get price
