Abstract. In Japan, gas insulated switchgears (GIS) have been applied widely since the field test and the commercial operation of 66 and 77kV switchgears in 1968 and 1969 respectively. The application has been expanded up to 500 kV and furthermore 1000 kV class equipment. This is due to the fact that the gas insulated equipment can meet the requirements in the country that huge electric power has to be supplied in the metropolitan and industrial areas and also the severe environmentalGet price

sf6 gas: The Truths and Myths of this Greenhouse Gas

Sulfr hexafluoride is damaging to the environment: TRUE. Along with CFCs, HCFCs, HFCs and PFCs, gaz sf6 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’s “dirty little secret”: FALSE. sf 6 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 Sulfr hexafluoride is used in wind turbines: TRUE. insulating gas 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 insulating gas: 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.
