一、Desctiption
   The current transformer is casting resin,full enclosed and post type product. It js used for metering electric energy and current,relay protection jn the electrical system of rated frequency 50Hz or 60Hz and rated vohage 15kV or 20kV. The transformers can be executed according to the standards IEC60044 -1 and GB1208.

二、Type designation

  
三、Construction
