As a premier china high voltage vacuum circuit breaker manufacturer, we engineer solutions for the world’s most demanding grids. Unlike conventional gas-insulated units, our high voltage vacuum circuit breaker line utilizes advanced vacuum interrupters for arc quenching, eliminating environmental risks. Whether you need a wholesale high-voltage vacuum circuit breaker for a 12kV industrial substation or a 40.5kV renewable energy site, our products ensure zero-restrike performance. Explore our full Vacuum Circuit Breaker range for custom configurations.

The Challenge

High maintenance costs and toxic gas leaks in traditional SF6 breakers often lead to grid downtime and heavy environmental penalties.

Our Fix

Our VCBs are “Sealed for Life,” requiring zero maintenance of the interrupter and providing an eco-friendly footprint with 20+ years of service.

Eco-Friendly Interruption

Pure vacuum arc quenching—no SF6 gas, zero GWP.

Modular Mechanism

Simple spring-operating mechanism for easy site maintenance.

Extreme Duty

Class M2 and C2 ratings for the most demanding switching cycles.

Anti-Condensation

Specialized insulation designed for humid and coastal climates.
