A method for manufacturing an electrical cable includes providing at least one core including an electrical conductor, and arranging at least one copper sheath around the at least one core. The arranging of the copper sheath includes providing at least one foil of copper having two opposite first edges; bending the foil of copper around the core until the first edges of the foil of copper are contacted with each other; welding the first edges of the foil of copper to each other to form a corresponding solder jointwelded joint; and deposing a copper coating on at least portions of the surface of the foil of copper at the welded joint. The deposing the copper coating is carried out by means of a thermal spray process.

A data line that is designed as a coaxial cable and has a line core that extends in a line longitudinal direction. The line core has at least one conductor surrounded at least by insulation and is surrounded by a multi-layer shielding foil, which has a non-conductive layer and a conductive layer. In an overlap region, a free end edge overlaps a further partial region, wherein additionally a conductive connection of the conductive layer at the end edge to the further partial region is formed such that a transverse current flow perpendicular to the longitudinal direction within the conductive layer is enabled. The conductive connection is formed optionally as a conductive strip and/or by a beveled end edge. In particular, the data line is a data line shielded exclusively via the shielding foil. The data line is used in particular in a motor-vehicle electrical system.
