ZW17-40.5 Outdoor High Voltage SF6 High Voltage Circuit BreakerDetailed product description：

ZW17-40.5 outdoor high-voltage SF6 circuit breaker is a three-phase AC 50Hz outdoor high-voltage electrical equipment, suitable for control and protection of 40.5kV transmission and distribution systems, and can also be used for connecting circuit breakers and opening and closing capacitor banks.

ZW17-40.5 series vacuum circuit breaker is an outdoor high-voltage switchgear with three-phase AC 50Hz, which can be widely used in 40.5kV power transmission and transformation systems as a means of breaking and closing load currents, overload currents, and short-circuit currents, especially suitable for places with frequent operation. The insulation performance of oral products is low, and the design is improved based on the theoretical basis of ZW17-40.5 products. 2. This product complies with the requirements of GB1984-2003 "AC High Voltage Circuit Breakers". Main features: 1. Outdoor vacuum arc extinguishing chamber is selected, which has the advantages of safety, reliability, and long service life; 2. Adopting new insulation materials to avoid the impact caused by inflation, oil filling, etc; 3. Current transformers have the characteristics of high precision, large capacity, variable ratio, and multiple stages; 4. Can be equipped with two mechanisms: electromagnetic operation or spring operation; 5. Circuit breakers have three types of structures: horizontal, central, and CT external.
