NOVELTY - The joint has a second armoring layer (11), positioned in an area neighboring outer mechanical casing (13) and surrounding at least one of the cable sections, which has one end that is mechanically connected to a casing while the other end is terminated at a distance from the casing. The second armoring layer includes elongated armoring units (11b) wound twisted in an opposite direction to the armoring wires of a first armoring layer (10) with respect to the longitudinal axis of the cable to increase the torsional rigidity of the area neighboring the casing.    USE - Joint for cable sections of electric power cable, e.g., three-phase sea cable.    ADVANTAGE - The impact from forces due to rotation of the cable is moved away from the joint to a section of the cable which is not affected by the jointing and to have normal torsional rigidity due to the second armoring layer the torsional rigidity of a single armored cable is restored in an area close to the joint. Torsional rigidity is achieved in two opposite directions since the armoring units of second armoring layer is wounded in a direction opposite the winding direction of the wires of the armoring layer on the cable. The second armoring layer is only applied in an area neighboring the joint in order to save costs since the first armoring layer extends along the entire length of the cable section and the second armoring layer is essentially shorter than the first armoring layer.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) a method for joining two sections of an electric power cable; and    (2) a use of the method for joining cable sections of the three-phase sea cable.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic sectional view highlighting a step utilized in the method for joining two sections of a three phase high voltage sea cable.
