REINFORCEMENT ARRANGEMENT FOR SUBMARINE CABLE CONNECTIONS

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.

主权项

1. Reinforcement arrangement applicable to the connections of submarine power cables, wherein the cable includes a conducting core of copper or aluminium with one or more polymeric and metallic layers that constitute insulation, screens and covers, and wherein the connections of the cables are made using known techniques such as, for example, welding, characterised in that it comprises a body that is placed in a radial manner upon the connection area of the cable and on the adjacent area of the outside covering of the cable, the body being made of a material reinforced with fibres of great mechanical strength, joined to the outer part of the cable through a mechanical attaching element, so that the connection area of the cable bears a breaking load of 96% to 100% of the breaking load of the cable without connection.
