一、 Introduction
    The current transformer is specially 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 transformer is open - close type, while installing can will feels with each other the machine is divided into two half, pack the electric cable mergeses for integral whole. There is three rubber pads in the bus hole, they are used in fixed the primary electric cable. It is small and light.
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
