gas circuit breakers equipment toshiba

Toshiba developed a series of switchgears with higher voltage and current capacity during the postwar era of high economic growth. From around 1970, the company shifted its developmental efforts from air-insulated switchgear to gas circuit breaker (GCB) and gas-insulated switchgear (GIS) systems using sulfur hexafluoride (SF 6), which has excellent insulation performance.
