Three-phase Three-column Amorphous Core is an ideal material for Yy and Dy style transformers. The transformers will have more harmonious and beautiful shape, smaller overlooking projective area, and better product structure efficiency. High-capacity transformer cores adopt tensile structure technology. Our main amorphous cores are as follows: 1) Three-phase Three-column Amorphous Cores with Tensile plate and muffler hole, suitable for High-capacity transformers; 2) Three-phase Three-column Amorphous Core without Tensile plate, suitable for Small-capacity transformers; Performance Advantages & Feature miniaturizing and lightening of the transformers, decreasing the direct cost, assemble easily and quickly, greatly improved the production capacity and reduce the noise at the same time.
