Abstract
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.
