摘要： The invention comprises a reinforcement arrangement used on connections of submarine cables, consisting of a body made up of a material reinforced with fibres of great mechanical strength that are arranged in a radial manner on the connection area of the cable and on the adjacent area of the outside covering of the cable, joined to the outer part of said cable through a mechanical attaching element. The invention is applied as protective elements aimed at protecting connections of submarine cables for the purpose of carrying electrical energy and placed on the seabed, making these connections very strong and elastic, and therefore suitable for bearing the great mechanical stress and tensions that must be born underwater. Additionally, the invention comprises a method by which the reinforcement arrangement is applied to the connections of two submarine cables.

摘要： A method and armoured cable for transporting an alternate current at a maximum allowable working conductor temperature, as determined by the overall cable losses, the overall cable losses including conductor losses and armour losses. The cable includes at least one core, including an electric conductor having a cross section area, and an armour surrounding the core along a circumference. The method includes: causing the armour losses not higher than 40% of the overall cable losses by having the armour made with a layer of a plurality of metal wires having an elongated cross section with a major axis, the major axis being oriented tangentially with respect to the circumference; and transporting the alternate current at the maximum allowable working conductor temperature, in the electric conductor having cross section area sized on the overall cable losses including the armour losses not higher than 40% of the overall cable losses.
