EI-type transformer silicon steel sheets are a key material used for manufacturing transformer cores. They are made by stacking silicon steel sheets with "E" and "I" shapes. Silicon steel is a special alloy steel primarily composed of iron (Fe) and silicon (Si). It is characterized by low iron loss and high magnetic permeability, which effectively reduces eddy current and hysteresis losses during transformer operation, thus improving transformer efficiency.
Due to their simple structure, ease of manufacturing, and low cost, EI-type silicon steel sheets are widely used in small transformers, power transformers, electronic equipment transformers, and other fields.
