12kV Vacuum Circuit Breaker,
Outdoor 12kV Vacuum Circuit Breaker,
10000 Times Outdoor Vacuum Circuit Breaker
VSmK vacuum circuit breaker is the first domestic circuit breaker to realize the maintenance-free concept. Its long-life vacuum interrupter uses epoxy casting and solid sealing technology to ensure that the arc extinguishing system is maintenance-free; the equipped high-reliability permanent magnet operating mechanism ensures that the operating mechanism is maintenance-free; the electronic control part is discarded The traditional auxiliary switch is replaced by a photoelectric proximity switch, and a fully electronic power supply and an intelligent control unit are used to ensure that the electronic control part is maintenance-free.
