ELECTRICAL CONDUCTOR WITH SURROUNDING ELECTRICAL INSULATION

摘要

An electrical conductor provided with an electrical insulation system surrounding the conductor, the insulation includes a first insulation layer surrounding the conductor and a second insulation layer surrounding the first insulation layer. The second insulation layer includes a second polymer and a second filler in the form of chromium oxide (Cr2O3), iron oxide (Fe2O3), or a mixture of chromium oxide and iron oxide, wherein the first insulation layer includes a first polymer and a first filler including dispersed nanoparticles.
