一、Instroduction
    The current transformer is special_ly designed for ring network cabinet. It is used for meeting electic energy and current, relay protection in the electrical system of rated frequency 50Hz or 60Hz and rated voltage 35kVo  The transformers can be executed according to the standards IEC60044 -1 and GB1208.
二、Type description

三、Construction
    The insulation box structure is applied for the current transformer. The secondary winding which is wound with high quality silicon - steel or alloy and high strength enameled wire is enclosed in the box,then semi - manufacture goods will be finished with high quality self - extinguishing resin casting. The insulation box is optimized ABS and with environmental conservation self - extinguishing characteristic.
四、 Technical data
   1、Basic insulated level:0.72/3kV
     Because the cable protects the primary main insulation, so, the insulation characteristics of secondary
winding are only examined. The secondary winding can be able to withstand the power frequency test voltage
of 3 kV to ground.
    2、rated secondary current：5A，1A
