Product Description

Product Description

LW36-72.5/1250A outdoor self energyhigh-pressure sulfur hexafluoride circuit breaker is a three-phase ac 50/60 Hz outdoor high voltage electric transmission and transformation equipment, By Opening or closing the rated current and fault current and conversion circuit to realizing the protection,control and operation of the power transmission and transformation system. The product can open or close brake and operate the auto reclosing very fast and realize the linkage of three pole electric.

The circuit breaker using the latest design principle, And it has much feature such as simple construction,small volume material consumption, It is necessary to the operation of the energy is small and high reliability,easy to install,low noise and so on. It is developed a new generation of high-pressure sulfur hexafluoride circuit breakerby ourselves.
