    Summary
    FZW13-12 type outdoor HV AC permanent-magnet vacuum load break switch is used in the power system with rated voltage 12kV, three phase AC 50/60Hz, to open and close the load current in power line, the loop current in loop power network, the inductive current of capacity load transformer and the capacitive current of capacitor bank(or cable). It can also close the short-circuit current and withstand the electrodynamic effect and electrothermal effect caused by the short-circuit current. The product conforms to the standards of IEC 60265-1, IEC62271-103 & GB/T3804: 3.6kV~40.5kV AC high voltage load break switch and IEC60694 & GB/T11022: high voltage switch apparatus and control device.
