Abstract: The present invention relates to a joint including two sections of an electric power cable, each cable section comprising at least one core member surrounded by a first armouring layer (10) for protecting the core member from tensile forces acting on the cable, the first armoring layer including a plurality of armoring wires arranged along the length of the cable and twisted in a first direction with respect to the longitudinal direction of the cable. The joint comprises at least one core joint between the core members of the cable sections, and an outer mechanical casing (13) surrounding the at least one core joint and mechanically connected to the first armoring layers of the cable sections, and a second armouring layer (11) positioned in an area neighboring the casing, surrounding at least one of the cable sections, and having one end mechanically connected to the casing and the other end terminated at a distance from the casing, and the second armouring layer includes a plurality of elongated armoring elements (11b) wound twisted in an opposite direction to the wires of the first armouring layer with respect to the longitudinal axis of the cable in order to increase the torsional rigidity of the area neighboring the casing. This invention also relates to a method for joining the two cable sections.

Abstract translation: 本发明涉及包括电力电缆的两部分的接头，每个电缆部分包括由第一铠装层（10）围绕的至少一个芯部件，用于保护芯部件免受作用在电缆上的张力，第一铠装 层，包括沿着电缆的长度布置的多个铠装线，并且相对于电缆的纵向在第一方向上扭曲。 所述接头包括在所述缆索部分的所述芯部件之间的至少一个芯接头和围绕所述至少一个芯接头的机械连接到所述缆索部分的所述第一铠装层的外部机械壳体（13），以及第二铠装层 （11），其位于与所述壳体相邻的区域中，围绕所述电缆部分中的至少一个，并且一端机械连接到所述壳体，并且所述另一端终止于与所述壳体一定距离，并且所述第二铠装层包括多个 与第一铠装层的电线相对于电缆的纵向轴线相反方向缠绕的细长的铠装元件（11b），以增加与壳体相邻的区域的扭转刚性。 本发明还涉及一种用于连接两个电缆部分的方法。
