Abstract

An anhydride-free impregnating resin for an electrical insulation body, the impregnating resin has an epoxy resin, a curing agent and nanoscale and/or microscale inorganic particles. An impregnable electrical insulating tape for an electrical insulation body has a curing agent applied to the electrical insulating tape. A method includes producing an electrical insulation body An electrical insulation body includes an anhydride-free impregnating resin, where the impregnating resin has an epoxy resin, a curing agent and nanoscale and/or microscale inorganic particles.
