ZW32 pole-mounted vacuum circuit breaker
ZW32 pole-mounted vacuum circuit breaker
The ZW32 outdoor pole-mounted high-voltage vacuum circuit breaker is rated for a voltage of 12kV and operates at a three-phase AC frequency of 50Hz. It is primarily used to interrupt and connect load currents, overload currents, and short-circuit currents in power systems. The circuit breaker features a three-phase pillar structure, ensuring stable and reliable interruption performance, with no risk of combustion or explosion. This product is suitable for use in substations and distribution systems of industrial and mining enterprises for protection and control purposes, and is particularly well-suited for rural power grids and locations with frequent operations, especially for the renovation needs of urban and rural power networks.

The ZW32 outdoor pole-mounted high-voltage vacuum circuit breaker is rated for a voltage of 12kV and operates at a three-phase AC frequency of 50Hz. It is primarily used to interrupt and connect load currents, overload currents, and short-circuit currents in power systems. The circuit breaker features a three-phase pillar structure, providing stable and reliable breaking performance, with no risk of combustion or explosion. The three-phase pillars and current transformers use outdoor epoxy resin solid insulation or indoor epoxy resin wrapped in silicone solid insulation. The circuit breaker can be equipped with a three-phase linked isolating switch, which has a clearly visible break point when the isolating switch is in the open state, and is equipped with an anti-misoperation interlock device between the isolating switch and the circuit breaker body. This product is suitable for use in substations and distribution systems of industrial and mining enterprises for protection and control, and is particularly suitable for rural power grids and locations with frequent operations, especially for the renovation needs of urban and rural power networks.
