Abstract (en)
[origin: WO2013041363A1] The invention relates generally to the field of insulating electric conductors against partial discharge and specifically to a method for producing an insulation system having improved partial discharge resistance and to an insulation system having improved partial discharge resistance. The invention shows for the first time the surprising erosion-inhibiting effect of adhesion promoters, such as organic silicon compounds, added to resin when admixing nano particulate fillers. As a result of the introduction of the adhesion promoters into the resin before the nano particulate filler, surprisingly good results are achieved. It is discussed whether the good results, as indicated in figures 2 to 4, can be attributed to a type of particle wetting of the nano particles as a result of particle wetting with the organosilanes. In any case, it can convincingly be shown that the admixture of adhesion promoters with the resin before the addition of the nano particulate filler can provide considerable advantages.
