Description

LW36-126 series outdoor high-voltage sulfur hexafluoide circuit breaker is an outdoor product, suitable for power grid with an altitude not exceeding 3000m, ambient temperature not lower than -30"C, pollution level not higher than grade IV AC 50Hz, highest voltage of 126KV. It can be used to cut off rated current, fault current or switching line to realize control and protection of power system. It can also be used as contact circuit breaker. 

The product with SF6 gas as the arcing and insulating medium, adopted the most advanced since the arcing technology, with the new spring operating mechanism, has a long life, small work operation, low noise, high reliability, price moderate, etc, in the current electric power equipment trend without oil, the process of large capacity, can completely replace imported products of the same type.
