Buy Sulfur Hexafluoride, sf 6 Supplier | SCI Analytical

The primary use of Sulfur Hexafluoride (insulating gas) is as a gaseous dielectric medium in the electrical industry for various voltage circuit breakers, switchgear and other electrical equipment; this often replaces oil filled circuit breakers (OCBs) that can contain harmful PCBs. Under pressure, Sulfr hexafluoride gas is used as an insulator in gas insulated switchgear (GIS) because it has a much higher dielectric strength than air or dry nitrogen.Get price

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
