Abstract (en)
[origin: WO2022013036A1] The invention relates generally to the field of insulating electrical conductors against partial discharge in the medium- and high-voltage ranges. In particular, the invention relates to an insulating system for an electric machine, in particular a rotating electric machine such as an electric motor and/or a generator. The invention provides for the first time a substitute for the conventionally used mica as a barrier material in an insulating system, such as the main insulation of rotating electric machines such as motors and/or generators. The substitute is based on a polyether-imide/siloxane copolymer, which can be processed two-dimensionally, for example by surface extrusion. In this way, sheets are produced and, after being processed in sheet form or as a laminate, can be used as planar insulating materials, or cut as strips, in insulating systems.
