Sf6 Gas Processing Equipments - vpiltd.com

Sulfur hexafluoride (SF 6) is an inorganic, colorless, odorless, non-flammable, extremely potent greenhouse gas which is an excellent electrical insulator. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. SF 6 is used in the electrical industry as a gaseous dielectric medium for high-voltage circuit breakers, switchgear, and other electrical equipment, often replacing oil filled circuit breakers (OCBs) that can contain harmful PCBs.

sf6 gas: The Truths and Myths of this Greenhouse Gas

Sulphur hexafluoride, commonly known as SF 6, has made a splash in the mainstream media of late. Several articles are pointing the finger at the growth in renewables—specifically wind turbines—as being responsible for the growth in SF 6 emissions, with some going as far as saying that the gas is the energy industry’s dirty little secret. In this spirit of transparency, we asked several experts from NTNU and SINTEF to separate the truths from the myths.
