一、 Introduction
    The current transformer is specially designed for ring network cabinet.lt is used for meeting electic energy and current, relay protection in the electrical system of rated frequency 50Hz or 60Hz and rated voltage 35kV.  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
    l、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
    3、Insulated class:E
    4、Self - extinguishing class:V-O
