• Sulfur hexafluoride - Wikipedia

    Sulfur hexafluoride or sulphur hexafluoride, is an extremely potent and persistent man-made 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 de

  • How Humidity Affects the Safety of Sulfr hexafluoride-Insulated Equipment

    When the humidity content of the gas reaches certain levels, the sulfur and fluoride begin to form highly toxic and corrosive products such as sulfur dioxide (SO 2), hydrofluoric acid (HF), and disulfur decafluoride (S 2 F 10). These compounds not only decrease the amount of dielectric insulator but also create an acidic environment that attacks and damages the internal surfaces of the gas tanks and can compromise safety.
