Panel discussion: The pros and cons of using sf6 gas gas in

However, as the distributors of Tamco medium voltage switchgear in South Africa, we do not profess to be experts on SF 6 that has been used as an insulating medium for over half a century. Malaysian Switchgear’s expertise lies in the layout design, wiring, testing, installation, commissioning and maintenance of the Tamco range of medium voltage switchgear panels up to 36 kV, as well as dry ice cleaning of compromised sub stations.

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
