The 126KV outdoor SF6 circuit breaker has the model number LW36-126. The LW series sulfur hexafluoride circuit breaker features a single-column, single-break contact structure per pole in its arc extinguishing chamber. It utilizes a self-energy arc extinguishing principle, generating airflow through an independent arc extinguishing chamber during the breaking process to cool the arc and interrupt the current. It is equipped with a CT motor-driven spring operating mechanism and a three-stage mechanical linkage. This product can be used as a control and protection device in power systems, and can also be used as a tie circuit breaker.
1. The operating altitude for the 126kV Outdoor SF6 Circuit Breaker shall not exceed 3000 meters above sea level;
2. The operating ambient temperature range is -30 to 40 degrees Celsius;
3. The maximum wind speed applicable to the 126kV Outdoor SF6 Circuit Breaker installation site is 34 m/s;
4. The pollution level is Class III (25 mm/kV).
