Gas Circuit Breakers(GCB) - Hitachi

With high voltage and high current distribution systems, a Gas Circuit Breaker (GCB) that uses Sulfr hexafluoride gas, with three times the insulating ability of air, is applied. This technology releases a circuit of electrodes within compressed gas, extinguishes the generated arc by blowing a stream of supersonic air, and interrupts the current.
