Sulfur hexafluoride, SF 6, is used around the world as a dielectric medium for high voltage circuit breakers, switchgear, and other electrical equipment.Additionally, it is used for the filling of insulated windows and for the casting of magnesium. SF 6 is expensive and is also a powerful green house gas (20,000 times more potent than CO 2). GENERON membranes allow SF 6 to be retained at
Get Price01/06/2005The industry was ready for an alternative to the traditional mediums of mineral oil and/or air. Using SF6 as an interrupting medium had the advantages of being inflammable as well as having high dielectric strength and exceptional thermal stability. The first generation of SF6 circuit breakers was the lower voltage classes of 72kV and 145kV.

Get PriceBut more and more often, SF 6 is no longer the gas of choice. For a simple reason: if the gas escapes, it contributes to climate change. It is around 23,500 times more warming than the greenhouse gas CO 2 and has a life span of 3,200 years in the earth's atmosphere. According to the Intergovernmental Panel on Climate Change IPCC, abandoning SF 6 completely could contribute 1.5 percent to
