KEY POINTSToshiba validates 300kV GIS and GCB using only natural-origin gases, fully eliminating SF6CO2-oxygen mixed gas with proprietary arc-quenching chamber meets applicable standard specifications for interruption and insulationPrototype design to start immediately, targeting commercial product launch within fiscal year 2028 Toshiba tests a 300kV gas circuit breaker using natural-origin gas. Toshiba Energy Systems & Solutions Corp. said it has confirmed the fundamental performance of 300kV gas-insulated switchgear (GIS) and gas circuit breakers (GCB) that use only naturally occurring gases — entirely eliminating sulfur hexafluoride (SF6) — marking a significant step in efforts to decarbonize high-voltage power infrastructure.
