Beschreibung
Zusammenfassung:	The invention relates to an impregnating formulation for a wrapping tape insulation of an electrical machine, comprising a resin formulation having at least one epoxy base resin and a hardener formulation having at least one hardener, wherein the resin formulation can react with the hardener formulation to form an insulation material (IM1-IM6). In addition to the epoxy base resin, the resin formulation comprises at least one component having at least one saturated and/or unsaturated epoxy cycloalkyl group, by means of which the glass transition temperature of the insulation material (IM1-IM6) is increased in comparison with an impregnating formulation without the component. The invention further relates to an insulation material (IM1-IM6) for a wrapping tape insulation of an electrical machine, a method for producing an insulation material (IM1-IM6) of this kind, and an electrical machine, in particular a medium-voltage and/or high-voltage machine, with an insulation material (IM1-IM6) of this kind.
