    • 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.
    • 一种用于高电压的直流电缆,其至少具有被绝缘层包围的内部导体,所述绝缘层被配置为承受导体与电缆周围之间的电压。 绝缘层由多个叠层的绝缘材料层形成,每个绝缘材料的顶部均具有隔离的金属区域。 连续的这种膜状层的金属区域在电缆的径向方向上至少部分地彼此重叠,从而在电缆的所述绝缘层中产生大量的小电容器。
