sf6 gas Gas Handling in Japan Focused on Emission Reduction from

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
