Product Description
Product Description

Introducing the ZW32-12, an advanced outdoor high voltage vacuum circuit breaker, known simply as the 'circuit breaker'. This state-of-the-art switchgear operates at a rated voltage of 12kV with three-phase AC at 50Hz. Designed for excellence, it excels in breaking and closing load currents, managing overloads, and handling short circuit currents effectively. With cutting-edge overload and short circuit protection, it meets the highest standards for control and measurement. What sets it apart is its capability for remote control and monitoring, making it an indispensable asset in substations and industrial and mining enterprises. Perfectly suited for high-frequency operational environments, this circuit breaker is a beacon of reliability and efficiency.

 

Structural features:

The circuit breaker boasts a robust three-phase pillar dry structure, ensuring durability and dependability.

With its fully enclosed design, it offers exceptional sealing performance. Its moisture-proof and anti-condensation capabilities make it ideal for high temperature and humid regions.

Employing vacuum arc extinguishing technology, the breaker guarantees reliable insulation like no other.

The breaker ensures reliable opening and closing performance, eliminating any risk of combustion or explosion.

Compact and lightweight, this maintenance-free device promises an extended service life, offering peace of mind.

Flexibility in operation is key; it can be manually, electrically, or remotely operated to suit diverse needs.

Strategically sealed at the bottom of the switch box, the operating mechanism is protected from outdoor environmental corrosion.

The restless mechanism is a marvel of engineering - featuring novel design, a straightforward structure, reliable dynamic performance, compact size, and an impressive service life of up to 10,000 operations.(Updated2025.3.5day)
