Products Description

EI Core is the most common type of core structure, mainly used in magnetic devices such as transformers, reactors, power adapters, inductors, etc. It is named because of its shape, which is a combination of "E sheet" and "I sheet". It has the characteristics of simple manufacturing, clear magnetic circuit and low cost. It is the core structure of traditional 50Hz~400Hz power frequency magnetic applications.

Key features of EI Core

Function	Description
Magnetic Flux Conduction Channel	Provides a closed magnetic circuit, transmits magnetic field energy, and converts voltage or current
Supports Winding Structure	The main column serves as the installation position for coil windings, facilitating compact design
Reduces Iron Loss and Eddy Current Loss	The multi - layer thin - sheet structure reduces circulating current, making the iron core more efficient
Flexible Processing and Assembly	The standard component structure is convenient for stamping, assembling, maintenance, and repair

We provide EI finished products and raw materials for EI cores：

Material Type	Properties	Typical Applications
Silicon Steel Sheets (Cold - rolled Oriented/Non - oriented)	Low cost, medium magnetic permeability, suitable for power frequencies of 50Hz - 400Hz	Power transformers, control transformers, industrial reactors, etc.
Amorphous Ribbons	Ultra - low loss, suitable for energy - saving transformers, excellent high - frequency performance	High - efficiency energy - saving transformers, inverter cores, etc.
Nanocrystalline Ribbons	Higher magnetic permeability and frequency response capability, low temperature rise, low noise	High - frequency power supplies, UPS, power filtering, precision instruments
