EI Lamination Core

We manufacture high-quality EI lamination cores, specifically designed for transformer applications, combining mature manufacturing processes with stable performance to meet the demands of standard power supplies and industrial transformers.
The EI core consists of interleaved “E” and “I” laminations, ensuring continuous magnetic paths, reducing leakage flux, and improving transformer efficiency. Its classic design benefits from mature production techniques, enabling high-volume manufacturing while maintaining reliable electrical performance.
The mechanical structure of the core is robust, offering strong vibration resistance and maintaining stable shape and dimensions during long-term operation, ensuring transformer safety and longevity. Its relatively low manufacturing cost makes it a preferred choice for economical power supplies and standard transformers.
EI lamination cores are suitable for a variety of applications, including switch-mode power supplies, industrial power, control transformers, and other standard power products, earning recognition in the industry for their excellent magnetic properties and stability.
