Abstract: A transmission cable includes a conductor or a bundle of conductors extending along a longitudinal axis, which is circumferentially covered by an insulation layer having an extruded insulation material, whereby the transmission cable passes the electrical type test as specified in Cigré TB496, whereby the rated voltage U0 is 450 kV or more. The type test includes subjecting the power cable to a DC voltage of 1.85*U0 during 10 to 15 cycles at negative polarity, followed by a polarity reversal with another 10 to 15 cycles at positive polarity at a DC voltage of 1.85*U0, followed by additional 2 to 5 cycles during at least 4 to 10 days at positive polarity, and wherein U0 is 450 kV, or 525 kV, or more.

Abstract: 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.
