The Zw15-38kV Automatic Outdoor Vacuum Circuit Breaker (Auto Recloser) integrates vacuum interruption technology with automatic reclosing functionality, delivering high breaking capacity, reliable operation, and maintenance-free performance for medium-voltage power grids (10-40.5kV), serving as a critical protection and control solution for outdoor power systems.
Product Description:
Designed for harsh outdoor environments, the Zw15-38kV Automatic Outdoor Vacuum Circuit Breaker (Auto Recloser) leverages advanced vacuum interrupter technology and a rugged stainless steel enclosure to ensure exceptional electrical endurance, weather resistance, and corrosion protection. Equipped with intelligent automatic reclosing capabilities, it efficiently restores power supply after transient faults, minimizing downtime for power plants, substations, industrial facilities, and distribution networks. Compliant with international electrical standards, this medium-voltage (38kV) circuit breaker features a magnetic actuator design with fewer moving parts, enabling 10,000 rated full-load operations while eliminating the need for oil or gas insulation—making it environmentally friendly, safe, and cost-effective for long-term service. Its separately housed electronic controls also allow convenient maintenance without aerial access equipment, enhancing operational safety and efficiency.
