High Voltage AC SF6 Circuit Breaker (GCB)

Xikai Limited produces outdoor high voltage AC SF₆ circuit breakers with voltage ratings from 40.5kV to 1100kV, rated current 1250~5000A, and rated short-circuit breaking current up to 63kA. The operating mechanisms are divided into spring mechanism and hydraulic spring mechanism. The spring mechanism uses a motor to store energy in the closing spring, and stores energy in the opening spring during closing operation; the hydraulic spring mechanism uses disc springs for energy storage instead of traditional compressed nitrogen, with opening and closing both driven by hydraulic transmission.
