A sheath for wrapping an elongated object is formed by an adhesive tape having a base strip having inner and outer faces, a first adhesive on the outer face, an adhesive-free overlay strip adhered to the first adhesive coating so as to leave a first exposed edge band on at least one of two longitudinal edges of the tape, and a second adhesive layer covering only part of an area of the inner face.

A cable that protects an object includes a sheath and a cylindrical reinforcement member disposed inside the sheath and that surrounds the object. The cylindrical reinforcement member has a first side edge and a second side edge that extend in a longitudinal direction. The cylindrical reinforcement member is formed of a cable reinforcement sheet including a first metal sheet and a second metal sheet joined to the first metal sheet. A portion of the first metal sheet overlaps a portion of the second metal sheet, and the overlapping portions define a joint portion where the first metal sheet and the second metal sheet are joined. The joint portion is inclined, from the second side edge to the first side edge, toward the first metal sheet.

The invention relates to a cable (1) with at least one strand (2) having twisted litz wires (3) for conducting electrical current and an insulation sheath (4) surrounding the at least one strand (2) for electrically insulating the at least one strand (2). The cable (1) has an interruption section (5) without an insulation sheath (4) between two cable sections (6, 6) with an insulation sheath (4). According to the invention, the twisted weave of the at least one strand (2) is loosened in the interruption section (5), in order to interrupt the transport of moisture through the cable (1), in particular through the at least one strand (2), that results from capillary pressure and/or temperature-related pressure differences along the cable (1), such that the pressure in the interruption section (5) can equalize with that of the exterior.
