Lugao proudly stands as the foremost 126KV Outdoor High Voltage SF6 Circuit Breaker supplier. Our LW Series, featuring the self-energy sulfur hexafluoride circuit breaker, boldly employs the self-interrupter principle—a revolutionary approach that dramatically reduces the pressure cylinder's diameter and weight. In the realm of high-voltage circuit breakers, Lugao leads with bold innovations that prioritize efficiency, compact design, and cutting-edge technology. Choose Lugao for groundbreaking solutions that redefine the standards of outdoor high voltage SF6 circuit breakers.

  This design leads to a decreased operating power requirement, enabling the integration of a spring operating mechanism.  The circuit breaker consists of three single-pole units, each mounted on a spring mechanism and combined on three brackets.  This configuration allows for both single-pole operation and the achievement of three-pole electrical linkage.  The spring mechanism is positioned on the bracket's side, while the electrical control system is housed inside the body.  The breaker's upper part features a single-pole circuit breaker interrupter, a middle pillar porcelain set, and the lower part serves for sealing, opening spring, and buffering purposes.
