| 摘要 |
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. |
