EI transformer is defined according to the shape of the iron-core, because the core is superimposed by the "E" type piece and the "I" type piece, so it is called the EI transformer. EI transformers are generally power frequency (low frequency) transformers (50HZ or 60HZ), which can be used as power transformers, audio transformers, EI reactors, etc.

The specifications of EI transformer are classified according to the length of silicon steel sheet, such as commonly used EI-19, EI-48, EI-57, EI-132, EI-150, etc.

For detailed classification, the total stack thickness of silicon steel sheets should also be considered. Some transformers are marked with EI-48*20. This "20" means that the total stack thickness of silicon steel sheets is 20mm, so it's EI-48, detailed EI-48*20.
