|---|---|
The ZW8-12 series adopts a vacuum interrupter with air insulation, paired with an electric spring operating mechanism, ensuring reliable arc-extinguishing performance.
The overall structure is three-phase common box type, with bushing inlet and outlet connections.
The vacuum interrupter uses ceramic housing and cup-shaped longitudinal magnetic field contacts, providing excellent breaking and making capacity for short-circuit currents.
The conductive rod is encapsulated with silicone rubber, enabling reliable performance in harsh climate and polluted environments.
Compact structure, lightweight body, and aesthetic appearance make it suitable for long-term outdoor applications.
The ZW8-12/630-20 outdoor high voltage vacuum circuit breaker is applicable to AC 50Hz three-phase power systems, primarily used to switch:
Load current
No-load current
Short-circuit current
It is widely used in 10kV urban distribution networks, rural power grids, and small-scale power systems, serving as an ideal replacement for traditional oil circuit breakers.
