ZW32 type pole-mounted vacuum circuit breaker

The ZW32 type outdoor pole-mounted high-voltage vacuum circuit breaker is an outdoor high-voltage switching device with a rated voltage of 12kV and a three-phase alternating current of 50Hz. It is primarily used for breaking and closing load currents, overload currents, and short-circuit currents in power systems. The circuit breaker adopts a three-phase post-type structure, ensuring stable and reliable breaking performance, with no risk of combustion or explosion. The three-phase posts and current transformers are insulated with outdoor epoxy resin solid insulation or indoor epoxy resin coated with silicone rubber solid insulation. The circuit breaker can be externally equipped with a three-phase linkage disconnector, which provides a clearly visible break in the off state and includes a safety interlock device to prevent misoperation between the disconnector and the circuit breaker body. This product is suitable for protection and control in substations and industrial power distribution systems, and is particularly well-suited for rural power grids and locations requiring frequent operation, especially for urban and rural grid renovation needs.
