Abstract
A system and a method are presented. The system includes an electrically conducting material and an electrical insulation system. The electrical insulation system includes a layered insulation tape that has a first layer and a second layer. The first layer includes a mica paper and a binder resin in a range from about 5 wt % to about 12 wt % of the insulation tape. The second layer includes a composite of layered nanoparticles dispersed in a polyetheretherketone (PEEK) matrix. The second layer laminates the first layer. The method includes attaching the first layer and the second layer with or without the addition of further resin; using the layered insulation tape as a turn insulation and ground wall insulation for an electrically conducting material; and impregnating the system with a nanofiller-incorporated resin by a vacuum pressure impregnation method, to form an insulation system within the system.
