Summary
       ZW20B-12 outdoor column high-voltage vacuum circuit breaker is an outdoor high-voltage switchgear with rated voltage of 12kV and three-phase AC 50Hz. It is mainly used for breaking and closing load current, overload current and short circuit current of power system. It is suitable for protection and control of substation, industrial and mining enterprises and urban and rural distribution network, especially for places with frequent operation and urban automation distribution network. The 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 is a maintenance free product with mature box type sealing structure and SF6 gas filled inside, which has good sealing performance and is not affected by the external environment. Its spring operating mechanism adopts direct chain main drive and multi-stage tripping system, which has high reliability and is the best product of the pole mounted circuit breaker.
        ZW20P-12 user boundary breaker (including controller) has fault detection function, protection control function and communication function (after configuration of communication module), which is suitable for installation at the responsibility boundary point of 10kV overhead distribution line user incoming line, as well as the branch line and terminal line meeting the requirements. After the equipment is installed and put into operation, it can automatically cut off the single-phase ground fault and phase to phase short circuit fault of the controlled branch line. The controller can realize real-time status monitoring and remote control function in the background (or PDA) by GPRS, CDMA, wired mode or Bluetooth communication.
