Abstract (en)

[origin: WO2012013439A1] The invention relates to mica-based insulation with increased electrical lifetime for rotating electrical machines based on impregnating resin with nanoparticulate filler. According to the invention, the reactivity, viscosity and grain size of the impregnating resin and nanoparticulate filler are matched to the requirements for the impregnation of the mica in such a way that the reaction mechanism that proceeds during the conduct of the process (impregnation, polymerization, storage) is at least not significantly affected by the nanoparticles.
