LW Series Outdoor High-Voltage SF6 Circuit Breaker
This product is suitable for use in 63kV-132kV power systems, providing protection and control for high-voltage transmission and distribution systems. It fully utilizes the arc-quenching effect to increase the pressure of SF6 gas in the pressure cylinder, significantly reducing the diameter of the pressure chamber and lowering the operating power required by the circuit breaker. This enables the use of a spring-operated mechanism with no oil leakage and higher reliability. Additionally, operating noise is greatly reduced, making it ideal for urban grid renovation projects.
