ELECTRICAL INSULATION SYSTEM

摘要

23232323An electrical insulation system comprises a first insulation layer (60) comprising a first polymer and a first filler in the form of nanoparticles and a second insulation layer (70) comprising a second polymer and a second filler in the form of chromium oxide CrO iron oxide FeO or a mixture of chromium oxide and iron oxide. At least one of the first and the second insulation layers (60 70) is in the form of a solid and flat sheet. By an insulation system combining the first insulation layer with well dispersed nanoparticles and the second insulation layer filled with CrO particles and/or FeO particles a synergetic effect of the two insulation layers provides an excellent shield and resistance of the insulation system against electrical discharges. The sheet material allows anybody to put together an insulation system without any special equipment.
