  • Name: KYN28A-12 Withdrawable Metal-clad AC Switchgear
  •   1.Brief Introduction

      KYN28A-12 Withdrawable metal-clad AC switchgear (intelligent) is applicable for power system with single bus and single bus branch (or double bus) for rated voltage (maximum voltage) of 7.2kV or 12kV and with frequency of 50Hz, as an indoor switchgear for accepting and distributing electric energy.

      It can be equipped with various types of middle-mounted circuit breakers, isolating handcarts and PT handcarts, which therefore satisfy various primary main circuit schemes.

      It can provide conventional monitoring and protection: to monitor circuit breaker, control temperature and humidity and protect microcomputer.

      It can be intelligent: power-driven in and out of handcart, power-driven operation on earthing switch, online monitoring on temperature rise and online monitoring on mechanical characteristics, etc.
