Description:
EI transformer lamination is made by Cold-rolled non-oriented electrical silicon steel sheet (CRNGO) or Cold-rolled oriented electric silicon steel sheet (CRGO), the thickness is from 0.23mm-0.5mm.
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.
Lulu Technology specializes in the production of transformer lamination, transformer core and lamination core, such as three-phase EI lamination, single-phase EI lamination sheet. She has now become a very important manufacturer for the most completed models of three-phase, single-phase EI lamination in Shanghai, China.
Application Fields:
Engineering Transformer and High-power Transformer in AC voltage mode.
