Abstract

Disclosed are insulating electric conductors against partial discharge and a method for producing an insulation system having improved partial discharge resistance and such an insulation system. There is an erosion-inhibiting effect of adhesion promoters, such as organic silicon compounds, added to resin when admixing nano particulate fillers. Good results may be attributable to a type of particle wetting of the nano particles as a result of particle wetting with organosilanes. The admixture of adhesion promoters with the resin before the addition of the nano particulate filler provides considerable advantages.
