Silicon Steel plays a very important role in laminated core-based transformers. As it increases the resistivity and reduces the loss caused by eddy current loops.And it has a compact design, the magnetic flux flowing through the core from primary to secondary winding does not get wasted.Increase in the overall efficiency of transformers.
Introduction:
Three-phase EI core is made by the silicon steel strip. The model of EI lamination in standard sizes is from
3PEI-17.5 to 3PEI-120.The gap sizes of the transformer lamination core can be customized.
