    10kV 12kV Permanent Magnetic Circuit Breaker Switch Three Phase For Smart Grid

    Product Introduction

    Product overview


    ---Outdoor high-voltage fast permanent magnet vacuum circuit breaker is an outdoor distribution vacuum circuit breaker with a rated voltage of 12kV and three-phase AC 50Hz.


    ---Outdoor high-voltage vacuum circuit breaker is a new generation of outdoor column vacuum circuit breaker developed to meet the needs of the smart grid.


    --- It is used to switch loads of different properties and frequent operations, and can break short-circuit current many times.


    ---It can be used as the 10kV side outgoing line of the main transformer of the substation and the switch on the column of the distribution network.


    ---It is the preferred equipment to realize the intellectual, automation, and miniaturization of the distribution network.
