Product Description

Product Description

ZW20-12F outdoor high voltage intelligent demarcation vacuum circuit breaker is an outdoor high voltage switchgear with rated voltage of 12kV and three-phase Ac 50Hz. it is mainly used to open and close the load current, overload current and short circuit current ofthe power system.
lt is suitable for protection and control of substations, industrial and mining enterprises and urban and rural distribution networks, especially suitable for places with frequent operations and urban gridautomatic distribution networks, This product is paired with a controller to meet the requirements of the distribution automation system and can reliably and efficiently complete the traditional recloser function. lt adopts mature box-type sealing structure, filled with SF6 gas inside, has good sealing performance, so that it is not affected by the external environment, and is a maintenance-free product. lts spring operating mechanism adopts direct-acting chain main drive and multi-stage trip system, which has high action reliability and is a good product for circuit breakers on columns.
