The ZW20-12F outdoor pole-mounted high-voltage intelligent vacuum circuit breaker is an outdoor high-voltage switchgear with a rated voltage of 12kV and three-phase AC 50Hz. It is mainly used to break and close the load current, overload current, and short-circuit current in power systems. It is suitable for protection and control in substations, industrial and mining enterprises, and urban-rural distribution networks, especially for frequently operated sites and urban network automated distribution networks.
When matched with a controller, this product can meet the requirements of distribution automation systems and reliably and effectively perform the function of traditional reclosers. It adopts a mature box-type sealed structure, with SF₆ gas filled inside, ensuring excellent sealing performance. This design protects it from external environmental influences, making it a maintenance-free product. Its spring operating mechanism uses a direct-acting chain main transmission and a multi-stage tripping system, featuring high operational reliability, thus making it an ideal choice for pole-mounted circuit breakers.
