Abstract: It is proposed a wound conductor arrangement for an electrical machine: the wound conductor includes ma wound conductor comprising an electrically conductive material having an electrical conductivity value, and an insulation layer being at least partially provided around the wound conductor by a shrinkable tube comprising insulating material. The wound conductor arrangement further includes an intermediate layer provided between the wound conductor and the insulation layer. The intermediate layer has a conductivity value less than the conductivity value of the wound conductor. Further, an electric machine is proposed including the wound conductor arrangement. A method is described for insulating a wound conductor for an electrical machine.
