The present disclosure relates to insulation. Teachings thereof may be embodied in a solid insulation material, especially in tape form, the use thereof in a vacuum impregnation process and to an insulation system produced therewith, and also an electrical machine comprising the insulation system, especially for the medium- and high-voltage sector, namely for medium- and high-voltage machines, especially rotating electrical machines in the medium- and high-voltage sector, and to semifinished products for electrical switchgear. For example a solid insulation material with an anhydride-free impregnating agent may include: a carrier; a barrier material; a curing catalyst; and a tape adhesive. The curing catalyst and the tape adhesive are inert toward one another but react under the conditions of a vacuum impregnation process if combined with an anhydride-free impregnating agent having gelation times of 1 h to 15 h at impregnation temperature. The tape adhesive is free of oxirane groups and includes at least two free hydroxyl groups.
