LW16-40.5 Outdoor SF6 Circuit Breaker

General LW16-40.5 outdoor SF6 circuit breaker is an outdoor switchgear using SF6 gas as insulating and arc-extinguising medium, mainly used in AC 50Hz three-phase power system. It is used to switch rated current, fault current and capacitor bank as well as to connect circuit breaker in industrial and mining enterprises, power plants and subatations and carry out the control and protection to the power transmission line and equipment. The circuit breaker is equipped with CT10 AC/DC spring operating mechanism. The circuit breaker has the features of excellent insulation performance and arcing performance, strong envirommental adaptable ability, convenient installation and operation, simple maintenance, long period of non-repairing, no need to recast the base.
