Cold Rolled EI Lamination Silicon Steel Transformer Core

The iron core is the main magnetic circuit part in the transformer. It is usually formed by stacking hot-rolled or cold-rolled silicon steel sheets with high silicon content and coated with insulating paint on the surface. The iron core and the coil wound on it form a complete electromagnetic induction system. The power transmitted by the power transformer depends on the core material and cross-sectional area.

1. High frequency class: Ferritecore
Ferritecore is used in high-frequency transformers. It is a ceramic magnet with a spinel crystalline structure. This spinel is iron oxide and other divalent metal compounds. For example, kFe2O4 (k stands for other metals), currently commonly used The metals are manganese (Mn), zinc (Zn), nickel (Ni), magnesium (Ng), copper (Cu).
Its commonly used combinations are manganese zinc (MnZn) series, nickel zinc (NiZn) series and magnesium zinc (MgZn) series. This material has high permeability and resistive properties, and its use frequency range is from 1kHz to more than 200kHz.
