Overview
The ZW20-12F Outdoor High-Voltage Intelligent Sectionalizing Vacuum
Circuit Breaker is a high-voltage switchgear device with a rated
voltage of 12 kV and operates on three-phase AC at 50 Hz. It is
primarily used to interrupt and close load currents, overload
currents, and short-circuit currents in power systems.
This breaker is suitable for substations, industrial and mining
enterprises, and urban-rural distribution networks, serving as a
protective and control device. It is especially ideal for locations
with frequent operations and automated urban distribution networks.
Paired with a controller, it meets the requirements for
distribution automation systems and can reliably perform the
traditional function of a recloser.
The device features a mature box-sealed structure filled with SF₆
gas, providing excellent sealing properties to shield it from
environmental impact, making it a maintenance-free product. Its
spring-operated mechanism utilizes a direct-action chain drive and
multi-stage tripping system, offering high operational reliability,
making it an ideal choice for pole-mounted circuit breakers.
