1  Introduction

Applicable for Yy Group(such as Yyn0) and Dy Group (such as Dyn1) transformers which will have more harmonious and beautiful shape, smaller topview projective area, better product structure efficiency. Large transformer cores adopt tensile structure technology.

Our main amorphous cores as below：

1)  Three-phase Three-column Amorphous Core with Tensile plate and muffler hole, suitable for large transformer;

2)  Three-phase Three-colunm Amorphous Core without Tensile plate, suitable for small ransformer;

2  Feature

Able to make the transformer miniaturization and lightening, decrease the direct cost, easy and fast to assemble, greatly improve the productivity and reduce the noise.

1)  Raw material:  J1K101 iron based amorphous ribbon from Henan Zhongyue Amorphous New Materials Corp. Ltd (width:120 mm, 140 mm,170 mm,213mm）

2)  Flux density :   1.25~1.35 Tesla

3 )  Material density: 7.18 g/cm^3

4)   Lamination coefficient:  no less than 86%
