The ZW32-24 outdoor high-voltage vacuum circuit breaker isdesigned for a rated voltage of 24kV and operates at a frequency of50Hz in three-phase AC.lt serves as outdoor distribution equipmentfor power stations, industrial and mining enterprises, and ruralpower grids with frequent operations. lt can also function as a ringnetwork power supply unit and terminal equipment for thedistribution, control, and protection of electrical equipment. Whencombined with an isolation switch, it can be used as a sectionaswitch. The breaker is primarily used for opening and closing loadcurrents, overload currents, and short-circuit currents in powersystems. lt features a patented solid-sealed vacuum interrupter.external insulation with silicone rubber bushings for long life, highreliability, good weather resistance, easy transportation, and cost-effectiveness.The operating mechanism employs a compact, highlyreliable spring operating mechanism with a simple structure and amechanical life of up to 20,000 operations. lf an advancedpermanent magnet mechanism is used, mechanical performance iseven more stable and reliable. The breaker can be equipped with amanual opening and closing mechanism and can be manuallyoperated on-site when necessary. This breaker, when paired with acontroller, becomes a recloser, enabling remote control, telemetry.remote signaling, and remote adjustment, known as the “fourremote” functions.
