ZW17-40.5 outdoor high voltage SF6 circuit breaker

Outdoor high-voltage circuit breaker Outdoor high-voltage circuit breaker is a three-phase AC outdoor high-voltage electrical equipment. It is suitable for the control and protection of power distribution systems. It can also be used for contact circuit breakers and switching capacitor banks.
The column vacuum circuit breaker is a three-phase AC outdoor high-voltage switchgear. It can be widely used in substation systems to break and close load currents, overload currents and short-circuit currents. It is especially suitable for places with frequent operations. In order to solve the problem of low insulation performance of imported products, the design is improved based on the theory of the product. The product complies with the requirements of "AC High Voltage Circuit Breaker". The main features are external vacuum arc extinguishing chamber, which has the advantages of safety, reliability and long life. It uses new insulation materials to avoid the influence caused by gas filling and oil filling. The current transformer has the characteristics of high precision, high capacity, large transformation ratio and multi-stage. It is equipped with electromagnetic operation. Or spring-operated two mechanisms, the circuit breaker has three structures: horizontal, central, and external.
