Product introduction: ZW20-12F outdoor high-voltage intelligent demarcation vacuum circuit breaker is an outdoor high-voltage switchgear with a rated voltage of 12kV and three-phase AC 50Hz. It is mainly used for breaking and closing the load current, overload current and short-circuit current of the power system. It is suitable for protection and control of substations, industrial and mining enterprises and urban and rural distribution networks, especially for places with frequent operations and automatic and automated distribution networks of urban networks. This product is matched with the controller, which can meet the requirements of the distribution automation system, and can reliably and effectively complete the traditional recloser function. It adopts a mature box-type sealing structure, filled with SF6 gas, and has good sealing performance, so that it is not affected by the external environment, and is a maintenance-free product. Its spring operating mechanism adopts direct-acting chain main drive and multi-stage tripping system, which has high reliability and is the best product for pole-mounted circuit breakers. Normal conditions of use: Ambient temperature: not higher than +40ºC, not lower than -15ºC; Air relative humidity: the daily average is not more than 95%, and the monthly average is not more than 90%; The altitude does not exceed 1000 meters; Earthquake intensity does not exceed 8; A place free from fire, explosion, serious pollution, chemical corrosion and severe vibration.
