Abstract: A reinforcement arrangement for use with the connections of cable spices of undersea power cables that transport of electrical energy is disclosed. Each power cable includes an inner conducting core of copper or aluminum with one or more concentric polymeric and metallic layers that constitute insulation, screens and covers. The reinforcement arrangement is applied to the splicing of two cables at the conducting cores of each power cable, called a conducting cores connection area. The reinforcement arrangement includes a body that is disposed radially on the conducting cores connection area and on over the adjacent area of the outside outer covering of the power cable. The body is joined to the outer part covering of the power cables through a mechanical attaching element. The invention also relates to a method used to apply the reinforcement arrangement to the junctions of two submarine cables.

Abstract: The joining of very long electrical conductors should be more sturdy than what is provided by a simple bush, which joins same when said conductors are to be located on the sea bed in a very irregular manner and with stress on the bush or elevated joining means, a consequence, in addition to the irregularity of the aforementioned, of the great weight of the conductors. For this reason the method that is the aim of the invention consists of welding the conductors, perforating the reinforcement bush, placing same in the welding area of the conductors and welding the bush, and the subsequent deformation of the bush until the diameter of the bush is equal to that of the conductors.

Abstract: A metallic conductor (21) including an assembly of wires (22) having a predetermined polygonal cross-section. A flexible cable (23) is formed from a plurality of the multi-wire conductor (21) having a predetermined polygonal cross-section that are insulated.
