The ZW20-12 series outdoor pole-mounted intelligent high-voltage circuit breaker adopts a miniaturized spring operating mechanism design, making it more stable and reliable. The enclosure uses sealing, explosion-proof, and insulation technology, with good overall sealing performance. This product uses vacuum arc extinguishing and SF6 gas as the insulation medium, making it a maintenance-free, high-quality pole-mounted circuit breaker.
The ZW43-12 type outdoor high-voltage vacuum circuit breaker is a 12kV rated voltage, three-phase AC 50Hz outdoor power distribution equipment. It is suitable for use in substations and industrial and mining enterprise power distribution systems for protection and control, as well as in rural power grids with frequent operations. It can also be used as a ring network power supply unit and terminal equipment for power distribution, control, and protection of electrical equipment.
