A system and a method are presented. The system (10) includes an electrically conducting material (12) and an electrical insulation system (24). The electrical insulation system (24) includes a layered insulation tape (30) that has a first layer (32) and a second layer (34). The first layer (32) includes a mica paper and a binder resin in a range from about 5 wt% to about 12 wt% of the insulation tape (30). The second layer (34) includes a composite of layered nanoparticles dispersed in a polyetheretherketone (PEEK) matrix. The second layer (34) laminates the first layer (32). The method includes attaching the first layer (32) and the second layer (34) with or without the addition of further resin; using the layered insulation tape (30) as a turn insulation (14) and/or a ground wall insulation (22) for an electrically conducting material (12); and impregnating the system (10) with a nanofiller-incorporated resin by a vacuum pressure impregnation method, to form an insulation system (24) within the system (10).
