摘要： A non-corrugated cable 10 with a hollow core 20, suited for subsea operations at big sea depths and corrosive environments has a core 20 with a tube shaped non-metallic material for withstanding corrosion. A first inner armouring layer 30 is wounded onto the core 20, and at least a second armouring layer 40 is wounded onto the first inner armouring layer 30. Each armouring layer is laid counter-helically on each other for providing radial reinforcement of the core 20. The first inner armouring layer 30 has a smaller diameter of its wires than the second armouring layer 40. An outer protective non-corrosive sheath 50 is covering said armouring layers.

摘要： The invention concerns a power cable suitable for providing power to and from a downhole tool situated within a borehole. The cable comprises at least one inner conductor comprising at least one first electrically conductive material, at least one inner insulating layer surrounding the inner conductor(s), comprising at least one electrically insulating material, an armour sheath surrounding the inner insulating layer(s) comprising at least one second electrically conductive material and at least one outer conducting layer surrounding, and electrically contacting, the armour sheath, comprising at least one third electrically conductive material. The armour sheath further comprises at least one inner radial layer comprising a plurality of armouring wires with a diameter D and at least one outer radial layer electrically contacting the inner radial layer(s), the outer radial layer(s) comprising a plurality of armouring wires (6c) with a diameter d the diameter d being dissimilar to the diameter D, and wherein said armouring wires are radially arranged, in a closed packed structure in order to maximize the armour sheath density.
