Why should you use BS EN IEC 60404-8-11 - Fe-based amorphous strip?
Fe-based amorphous strip is regarded as a promising material to reduce energy loss in transformer cores and, consequently, to help mitigate global warming. The Fe-based amorphous strip is produced by a rapidly-solidifying, direct-casting process. The strip is intended primarily for the construction of wound cores of transformers for commercial power frequency (50 Hz and 60 Hz) applications. After appropriate heat treatment, the strip exhibits a significantly lower value of specific total loss in comparison with grain-oriented electrical steel strip for the same applications. It is associated with low hysteresis loss due to low magnetic anisotropy and with low eddy current loss due to high resistivity and reduced thickness.
In this regard, BS EN IEC 60404-8-11 provides requirements of magnetic properties, geometric characteristics, tolerances and technological characteristics, as well as inspection procedures.
BS EN IEC 60404-8-11 covers Fe-based amorphous strips grades that are grouped into two classes:
- Conventional grades
- High permeability grades
Technological properties and magnetic properties of both these grades of Fe-based amorphous strip are provided in BS EN IEC 60404-8-11. Properties such as magnetic polarization, thickness, width, stacking factor, conventional density, and their preferred values are covered in BS EN IEC 60404-8-11.
Complying with BS EN IEC 60404-8-11 guidance can help assess electrical and magnetic quantities of Fe-based amorphous strip. Thus, you can deliver Fe-based amorphous strips that offer low loss, high stability and flux density. As a result, you can demonstrate the reliability and credibility of your products for its intended use in magnetic applications.
