EI transformer is a traditional transformer. The core of EI transformer is combined by lamination E and I, so it is called EI transformer or laminated transformer. EI transformers are widely used in electronic equipment, not only it is an old type transformer, but also it is an economic transformer. It is usually used as power transformer at 50-60Hz. In audio applications, EI transformer is commonly used as tube power transformer and output transformer. Because there is air gap between E lamination and I lamination, and the air gap is easily adjustable by filling some medium, it is suitable to make output transformers and chokes.
Introduction:
Single phase EI core is made by the silicon steel strip. The model of EI lamination in standard sizes is from
EI-30 to EI-360.The gap sizes of transformer lamination core can be customized.
