LW16-40.5 outdoor sulfur hexafluoride circuit breaker is an outdoor device used in AC 50Hz three-phase power system for control and protection of industrial and mining enterprises, power plants and substations. This product can be operated frequently and can be used as a connecting circuit breaker and a circuit breaker for capacitor banks and reactor groups.

LW36-126(145) outdoor self-energy type circuit breaker is six sulfur hexafluoride gas as insulation and arc extinguishing medium , CT30 spring operation mechanism and the principle self-blown arc extinguishing of single variable pressure distance. The product is suitable for 72.5kV (126kV) three-phase AC 50HZ power system, which is used for points and load current , overload current and short circuit current.

LW58-12KV outdoor pole-mounted SF6 circuit breaker is a product developed by our company in response to the new requirements of the State Grid's 10kV primary and secondary integrated pole-mounted circuit breaker access to the grid. The switch configuration fully meets the State Grid's primary and secondary integrated requirements, which is convenient for the State Grid's unified procurement and batch production. The switch has a compact structure, reasonable layout, and complete functions. All indicators meet the State Grid's primary and secondary integration requirements; it uses protection CT, zero-sequence CT and zero-sequence voltage sensor with unified parameters, which has the characteristics of wide measurement range, high measurement accuracy and high reliability.
