LW*****6(**5)/T******0 self-energized SF6 circuit breaker is AC (*0Hz) outdoor high voltage apparatus, which is used to open and close rated current, fault current or lines conversion, and then the operation, protect, and control for electrical power system can be achieved. The three phases fast auto-reclosing functions can also be achieved by the product. This type of circuit breaker has advance design with simple structure, and the three single poles stand on a crossbeam. The crossbeam is fixed by two brackets. The spring operating mechanism is installed below the crossbeam. Through driving setup such as linkage arm etc, the three poles synchronising actions**-opening and closing operation are achieved. Each column pole consists of a arc chamber, support insulator, and cantilever arm box. Because of its compact structure, small volume, and light weight, by the combination with isolation plug, the product can be used as movable type SF6 circuit breaker for indoor or out door substation. According to the national standard GB********3 and IEC standard, the product has passed all type tests. The circuit breaker has excellent interruption capability, reliable insulation, stronger carrying capacity, and longer electrical and mechanical durations.
