Circuit Breakers

ZCW10-40.5L Type Outdoor Enclosed Combined Electrical Apparatus is a complete set of combination electrical appliances that use air as the external insulation SF6 gas as the arc extinguishing medium. The control and protection of 72.5 KV transmission and distribution systems for three-phase AC can also be used for connecting circuit breakers and opening and closing capacitor banks. Suitable for urban substations, enterprise substations, and mountainous substations with tight land use.

LW8(A)-40.5 Outdoor High-Voltage Sulfur Hexafluoride Circuit Breaker is a three-phase AC 50Hz outdoor high-voltage electrical appliance, which uses SF6 gas as the arc extinguishing and insulation medium, adopts a pressure type arc extinguishing structure, and has strong breaking capacity. It can be widely used in power systems with a rated voltage of 40.5kV as a substation, power plant opening and closing rated current, short-circuit current, and can be used as a connecting circuit breaker and capacitor bank. The internal current transformer is for measurement and protection purposes, and is an upgraded product of the circuit breaker.

LW36-40.5 (W)/T2000-31.5 outdoor sulfur hexafluoride circuit breaker is an electrical equipment in AC 50Hz three-phase power systems, suitable for control and protection in rated voltage, 40.5 kV power systems. It is equipped with internal or external current transformers for measurement and protection purposes.

LW16-40.5 Outdoor Sulfur Hexafluoride Circuit Breaker is equipped with a CT20 spring operating mechanism, which adopts the self energy arc extinguishing principle and a single break structure. The three poles of each circuit breaker are mounted on a frame and achieve three-phase mechanical linkage through a transmission mechanism. Electronic control can achieve remote and local operation.

LW36-72.5 Porcelain Column Type High-Voltage AC SF₆ Circuit Breaker is equipped with a CT20 spring operating mechanism, which adopts the self energy arc extinguishing principle and a single break structure. The three poles of each circuit breaker are mounted on a frame and achieve three-phase mechanical linkage through a transmission mechanism. Electronic control can achieve remote and local operation.
