Operation Mechanism
VMV Modularized Operation Mechanism
VMV Modularized Operation Mechanism (with smart unit)
   Modularized design of the operation mechanism is the highlights of VMV circuit breaker. With opening module and closing module in one part, the independent operation mechanism makes the standardized production and maintenance much easier.
Gear Driving System
    We improved VMV circuit breakers' driving system, using the gear driving system instead of the traditional chain wheel driving system. The circuit breaker operation will run more smoothly with a longer mechanical life.
Opening Oil Buffer
The application of high-performance oil buffer can greatly reduce moving contact's over-swing and rebound during the circuit breakers' opening process. In this way, it avoids the reduction of mechanical life when vacuum interrupter is over-fatigue, resulted from contact's over-swing.
