LW36A-145KV Live Tank High Voltage 11kv 126kv 145kv Sf6 Circuit Breaker, with voltage from 40.5-550kV and rated current up to 4000A, manufactured by our company, are provided with three kinds of operating mechanism, pneumatic, spring and hydraulic type.
Motor is used in spring mechanism to charge closing spring and charge opening spring at closing. Disk spring is used in hydraulic mechanism to be charged instead of traditional compressed nitrogen gas for charge, and hydraulic driving is used at both opening and closing. Compressed air is used in pneumatic mechanism as driven force for open while spring is used for close. The three kinds of operating mechanisms have their own features and are used in circuit breakers of different voltage class respectively.Due to the unit structure in circuit breaker, there are advantages of minimized number of breaks,lower number of parts, simple structure,high reliability and long period of inspection.
