摘要： A method for heat treatment of an electric power cable, the electric power cable including a polymer-based electrical insulation system with a polymer composition. The method steps include placing the electric power cable having the polymer-based electrical insulation system into a heating chamber and exposing the polymer-based electrical insulation system to a heat treatment procedure when the electric power cable is located in the heating chamber. The step of placing the electric power cable into the heating chamber includes winding the electric power cable about a substantially vertical center axis to form a substantially horizontal first layer of a plurality of substantially horizontal turns of the electric power cable, winding the electric power cable about the center axis to form a plurality of substantially horizontal second layers, each second layer being formed by a plurality of substantially horizontal turns of the electric power cable and stacking the plurality of horizontal second layers above the first layer. An apparatus is provided for performing the method.
