Description

 Product Overview

The ZW32-12 Integrated Primary & Secondary Pole-Mounted Vacuum Circuit Breaker is a high-performance outdoor switching solution designed for 10kV distribution networks. It features advanced local feeder automation capabilities that operate independently of the main station and communication systems, making it ideal for smart grid applications.
This all-in-one pole-mounted switchgear uses short-circuit/earth fault detection technology, combined with intelligent control logic like positive pressure tripping and adaptive delayed reclosing. It enables automatic fault location, isolation, and power restoration, ensuring reliable and continuous power supply in complex distribution grids.

Core Features

  • Standalone Feeder Automation: Operates independently without relying on the main station or communication, reducing system complexity and enhancing reliability.
  • Advanced Fault Detection: Integrates short-circuit and earth fault detection to accurately identify and locate faults in real time.
  • Adaptive Control Logic: Supports positive pressure tripping, adaptive delayed reclosing, and multi-section coordination, enabling rapid fault isolation and power restoration.
  • Grid Compatibility: Perfectly adapts to multi-breaker and multi-interconnection distribution network architectures, improving overall grid resilience.
  • Integrated Design: Combines primary switching and secondary protection/control functions in a compact, pole-mounted unit for easy installation and maintenance.
  • High Reliability: Built with vacuum interrupter technology for excellent arc extinction and long mechanical life (≥10,000 operations).
