Product Description

LW10B column type SF6 circuit breaker is independently developed by our company, including 252kV,
363kV and 550kV products, which are used for making and breaking normal current, fault current and
changing over of circuit, so as to realize the control and protection of power system.
Each pole of LW10B-252 circuit breaker has one break; LW10B-363 and LW10B-550 consists of two breaks,whether including closing resistance or not is up to requirement. For all of these three kinds of products, each pole is equipped with a hydraulic operating mechanism, which can make single pole operation and/or three pole electrically gang operation.
