Product introduction
The AIERWAY ZW32-12 is a state-of-the-art, fully integrated outdoor pole-mounted vacuum circuit breaker designed specifically for medium-voltage distribution networks (12 kV systems). This innovative product combines high-performance primary switching equipment with intelligent secondary protection and control systems in a single, compact unit, delivering exceptional reliability, safety, and smart grid compatibility for modern power distribution applications.
Key Features & Technical Advantages
1. Advanced Integration Design
-Primary-Secondary Integration: Seamlessly combines the vacuum interrupting chamber (primary equipment) with microprocessor-based protection relays, measurement units, and communication modules (secondary equipment)
– Compact Architecture: Significantly reduced footprint compared to conventional solutions requiring separate control cabinets
– Factory Pre-configured: Pre-wired, pre-tested, and ready for installation, minimizing field commissioning time and potential errors
2. Vacuum Interruption Technology
– High Breaking Capacity: Typically 20-25 kA short-circuit interrupting capability
– Long Electrical Life: ≥10,000 full load operations
3. Smart Grid Communication
– Multiple Protocol Support: IEC 61850, DNP3.0, Modbus RTU/TCP, IEC 60870-5-101/104
– Remote Operation: Full SCADA compatibility for remote monitoring and control
