* powercore® H 18 is suitable for distribution and power transformers at industrial frequencies as well as for devices running at medium frequencies.

L = Magnetic domain refined by laser scribing. Other grades may be delivered with laser domain refinement if not agreed otherwise.

Magnetic properties measured by Epstein frame or by SST. When measured by SST, obtained values are converted to Epstein standard as defined in IEC 60404-8. Typical values represent the average performance level which will be obtained in a transformer for a given grade.
