Cold Rolled Silicon Steel EI UI Transformer Lamination Core EI28 to EI240 UI30 to UI100
Brief Induction of silicon steel laminations :
EI Lamination is made by the silicon steel strip.The model of EI lamination in standard sizes is from EI 28 to EI -240, and the model of EI lamination in non-standard sizes is from EI-36 to EI-360. the gap sizes of transformer lamination core can be customized.
UI lamination is made by the silicon steel strip.the model of UI lamination is from UI-30 to UI-100,and the hole size is from Φ 8 to Φ 14. the gap sizes of transformer lamination core can be customized.
Three -phase EI lamination is made by the silicon steel strip. the model of three-phase EI lamination is from three-phase (20) to three phase (100),and the hole size is from Φ4.5 to Φ14, The gap sizes of transformer lamination core can be customized.
