Abstract
A DC cable for high voltages having at least an inner conductor surrounded by an insulating layer configured to take the voltage to be taken between the conductor and the surroundings of the cable. The insulating layer is formed by a plurality of superimposed film-like layers of insulating material each having isolated areas of metal on top thereof. The metal areas of consecutive such film-like layers are at least partially overlapping each other as seen in the radial direction of the cable so as to create a large number of small capacitors in said insulating layer of the cable.
