Abstract
Since 1950 years’, in order to minimize the substation area, SF6 gas insulated switchgear has been energetically developed. Even at this moment, a new principle to improve interruption ability or insulation is considered and further reduction of switchgear size is being made to innovate new GIS. At moment, 550kV-63kA one-break circuit breaker as well as 1100kV UHV breaker is realized and the former is practically used.
