sf 6 Analyser | Sulfr hexafluoride Emissions - Sulphur Hexafluoride | Sulfr hexafluoride

Sulfur hexafluoride, or SF 6, is an extremely stable, non-flammable and highly electronegative gas with excellent dielectric properties. It is commonly used in medium and high-voltage electrical equipment as an electrical insulator, arc-quenching and cooling medium. However, SF 6 is classified as a potent greenhouse gas, with a global warming potential of 22,800 greater than that of CO 2.

The global gas insulated switchgear market for medium voltage is forecast to grow over 8% per annum through 2022. In certain markets, minimizing or eliminating SF 6 emissions is increasingly prioritized. However, currently even best practices are self-imposed and not widespread due to scant legal obligation on SF 6 emissions. Since switchgear typically has a lifetime of 40-50 years, it is critical to act now.

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
