Outdoor high-voltage intelligent vacuum circuit breake

ZW20-12
The ZW20-12 pole-mounted circuit breaker is an outdoor high-voltage power distribution equipment with a rated voltage of 12kV and a three-phase AC frequency of 50Hz. It adopts a three-phase common-tank layout design, utilizes vacuum arc extinction, and is insulated with zero gauge pressure SF6 gas. The operating mechanism allows for both manual and electric operations, and the enclosure protection level is IP67, ensuring maintenance-free operation under harsh environmental conditions. The circuit breaker can be equipped with either a spring mechanism or a permanent magnet mechanism, and an isolating switch can be added according to user needs.

  • Product Advantages
    Reliable sealing, maintenance-free
    The main circuit of the circuit breaker, as well as the secondary components and the operating mechanism, are all sealed in SF6 gas at zero gauge pressure, ensuring high product reliability
    Use safely
    An explosion-proof device is installed on the top of the box, ensuring that even in the event of an unexpected internal malfunction, there is no risk of explosion
    Connector
    Adopt high-quality aviation sockets made of stainless steel, with gold-plated pins, ensuring waterproof and airtight performance, and reliable connection
    The product can be equipped with a built-in current transformer for protection and measurement purposes
    At the same time, a zero-sequence current transformer can be built in to achieve ground fault protection function
    Gas-insulated pole-mounted circuit breaker
    Especially suitable for use in high-altitude areas
    It can be operated both electrically and manually
    It can be configured with both local remote control and remote control functions
  • Application Scenarios
    It is suitable for use in the overhead distribution systems of the State Grid and China Southern Power Grid for measurement, protection, and control purposes. It can automatically detect faults, provide protection, trigger alarms, and monitor the operation of the lines. It also features the ability to automatically isolate faults and restore power supply to non-faulty sections
