Zw32-40.5 high voltage vacuum circuit breaker 35kv
ZW32-12 outdoor high voltage AC vacuum circuit breaker is a three-phase AC outdoor high voltage power distribution
Zw32-40.5 vacuum switch is an outdoor switchgear with rated voltage of 40.5kv and three-phase ac of 50Hz.2. Power: it is mainly used for the load current, overload current and short-circuit current in the power system.It is suitable for protection and control in urban and rural power grid, and more suitable for frequent operation.3. Special point: the structure of the outdoor fixed sealing pole column is novel: the unique squirrel cage frame structure enables the inner blanking layer and the outer umbrella skirt to be formed by an automatic pressure injection of silicone rubber, and the original manual operation method is replaced by the mechanical control method to avoid the breakdown fault of the fracture insulation.External current transformer;The external operating mechanism can reduce the weight of the circuit breaker body, facilitate the assembly and debugging of the production process, and facilitate the operation, maintenance and maintenance after operation.(1) ambient temperature: the upper limit is +40℃, and the lower limit is -40 ℃;(2) elevation: not higher than 1000 meters;(3) relative humidity: the daily average is no more than 95%, and the monthly average is no more than 90%.
