          ZN85-40.5


          INDOOR HIGH VOLTAGE
          VACUUM CIRCUIT BREAKER




          Overview
          ZN85-40.5 indoor high-voltage vacuum circuit breaker is suitable for three-phase AC 50Hz, 40.5kV system. It can be used for industrial and mining
          enterprises, power plants and substations as switching load current, overload current fault current, and is suitable for frequent operation occasions. This
          circuit breaker adopts up and down arrangement structure, which effectively reduces the depth of the circuit breaker. And adopt composite insulation
          structure, three-phase arc extinguishing chamber and associated charged body separated by three independent epoxy resin insulation shells. After using
          composite insulation structure, the circuit breaker meets the requirements of air distance and creep distance under normal operating conditions And
          effectively reduce the volume of the circuit breaker, the main conductive loop vacuum interrupter and the dynamic and static conductive connection are
          installed in the insulating cylinder, so that the phase is only 300mm. The main circuit electrical connections are all fixed connections with high reliability.
