Abstract
A method for producing an electrical insulation material includes the steps: providing a liquid-crystalline polymer; shaping the liquid-crystalline polymer to give an insulation film in such a manner that the mesophase of the liquid-crystalline polymer is present in the insulation film, whereby the molecules of the polymer are aligned in a preferred direction in the insulation film; laminating a plurality of insulation films to give a layer complex forming the electrical insulation material, wherein the layer complex has at least one insulation film which differs in the preferred direction of the molecules thereof from the preferred direction of the molecules of another insulation film.
