Material:Using high quality CRGO silicon steels with low iron-loss and high magnetic flux density in thickness of 0.23mm,0.27mm.
Charcteristic:this cores in triangle arragement and tightly wound by a specialiaed machine with a continuous strip and without air gap in the magnetic circuit.the three magnetic circuit are in same length and all are the shortest.the cross section is almost round,which can save more materials,improve the performance,reduce the core loss and noise and keep balance of 3 phase,All these advantages built up such a special transformer core.
Application:Widely used in S13 distribution transformers with stereo wound core.
