Abstract
The invention relates to a grain-oriented magnetic steel sheet including an electrically insulating coating made of an amorphous carbon-hydrogen network, which is applied after final annealing in order to ensure electrical insulation of the individual layers of the sheet. The grain-oriented magnetic steel sheet including the electrically insulating coating made of an amorphous carbon-hydrogen network can be used in transformers.
