Three-phase EI lamination

Three-phase EI laminations are available in multiple grades, distinguished by varying silicon content and thickness, tailored to specific application requirements. Within these grades, higher silicon content enhances magnetic saturation characteristics, while reduced lamination thickness helps minimize energy loss. The selection of an appropriate grade depends on critical factors including operating frequency, voltage, and core dimensions to ensure optimal system performance.
Tianxiang’s three-phase EI lamination dimensions range from EI-13 to EI-100. These laminations are widely utilized in power transformers, electric motors, and diverse electrical equipment where efficient power transmission and distribution are essential for three-phase systems, delivering enhanced magnetic properties, lower core losses, and improved efficiency in three-phase electrical applications.
