Abstract: An electrical insulation system includes a first insulation layer having a first polymer and a first filler in the form of nanoparticles, and a second insulation layer including a second polymer and a second filler in the form of either chromium oxide, Cr2O3, iron oxide, Fe2O3, or a mixture of chromium oxide and iron oxide. At least one of the insulation layers is in the form of a solid and flat sheet. An insulation system combining the first insulation layer with well dispersed nanoparticles and the second insulation layer filled with Cr2O3particles and/or Fe2O3 particles.
