The invention relates to an electrical insulation material and / or impregnating resin for the winding tape insulation, the insulating material formed therefrom by hardening and an insulation system, for example an insulation system for a rotating electrical machine, in particular a medium or high voltage machine. The invention provides for the first time an insulation material, ie a composition for a curable mixture which forms an insulating material, in which, under the same conditions, the service life of the conventional systems is exceeded by up to 8 times during operation. This is attributed to the symbiotic combination of substitution of the conventional epoxy resin at least partially by SiR2-O backbone forming components together with inorganic nanoparticles and a sintering additive which causes the fusion of the nanoparticles in the base resin. |
