F-Class DMD Prepreg is made by impregnating F-Class DMD with modified epoxy resin and partially curing it to a controlled B-stage condition. During final heat treatment, the resin cures and bonds the insulation to the winding conductor or foil.
F-Class DMD Prepreg is made by impregnating F-Class DMD with modified epoxy resin and partially curing it to a controlled B-stage condition. During final heat treatment, the resin cures and bonds the insulation to the winding conductor or foil.
It is selected for dry-type transformer coils where electrical insulation and winding consolidation are required in one material.
