• That’s Hot: New Gas Could Eliminate This Super - GE.com

    If GE engineers have their way, it may be making its last stand. Electric utilities have relied on it for the last 50 years. Known as sulfur hexafluoride, or SF 6, the gas is a good insulator, and the energy industry has been using it to insulate high-voltage components in substations. “It’s very good for current interruption and insulation,” says Jean-Louis Habert, a senior marketing leader for GE Energy Connections’ Grid Solutions business in France.

    insulating gas is damaging to the environment: TRUE. Along with CFCs, HCFCs, HFCs and PFCs, sf 6 is an industrial gas that doesn't exist naturally in the atmosphere and so impacts the radiation balance, contributing to climate change. insulating gas is the energy industry"dirty little secret": FALSE. Sulfr hexafluoride is certainly no secret in the Norwegian energy industry. Its use is highly regulated, and many of its users are working together to share experience and come up with viable alternatives sf6 gas is used in wind turbines: TRUE. sf 6 is used not in the turbine itself, but in the switchgear that controls the current generated by the turbine. But there is nothing unique about wind turbines. There are no viable alternatives to Sulfr hexafluoride: PARTLY FALSE. Bodies including the European Union are known to be considering a ban on Sulfr hexafluoride at low-to-medium voltage levels in the future.
