E.l Laminate Core
Sep 29, 2025
Leave a message
CRNO EI Lamination Core refers to a type of Cold Rolled Non-Oriented (CRNO) steel used for the production of transformer cores, particularly for electrical machines such as transformers, motors, and inductors. The EI lamination core is a common configuration in which the CRNO material is formed into E-shaped and I-shaped laminations that are stacked together to create a magnetic core.
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-28.2 to EI-288. The gap sizes of transformer lamination core can be customized.
