High-performance 35kV Three-Phase Automatic Recloser designed for advanced power distribution networks. This ZW32-40.5 series switchgear features a vacuum interrupter with motor-spring charged mechanisms, supporting rated currents up to 1250A and 20kA short-circuit breaking. Equipped with an intelligent electronic controller supporting GPRS/RS485 and IEC 60870-5-104 protocols for seamless SCADA integration and remote grid automation.
This model is widely used in overhead power distribution, especially in rural networks, wind and solar farms, and industrial feeders, where fast, automatic restoration significantly improves system reliability.
