GIS | High-Voltage Gas Insulated Switchgear Substations

A gas insulated substation (GIS) is a high voltage substation in which the major structures are contained in a sealed environment with sulfur hexafluoride gas as the insulating medium. GIS technology originated in Japan, where there was a substantial need to develop technology to make substations as compact as possible. The clearance required for phase to phase and phase to ground for all equipment is much lower than that required in an air insulated substation; the total space required forGet price

gaz sf6 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
