摘要： A method (200) for manufacturing an electrical cable (100) is provided. The method comprises providing at least one core (105) comprising an electrical conductor (110), and arranging at least one copper sheath (120) around the at least one core (105). Said arranging the copper sheath (120) comprises providing (202) at least one foil of copper (300) having two opposite first edges (310); bending (204; 206) the foil of copper (300) around the core (105) until the first edges (310) of the foil of copper (300) are contacted to each other; welding (206) the first edges (310) of the foil of copper (300) to each other to form a corresponding solder jointwelded joint (320); deposing (208) a copper coating (354) on at least portions of the surface of the foil of copper (300) at the welded joint (320). Said deposing (208) the copper coating (354) is carried out by means of a thermal spray process.

摘要： Process for producing an energy cable comprising at least one electrically conductive core and at least one thermoplastic electrically insulating layer, which comprises the steps of: impregnating a thermoplastic material in subdivided solid form, having a melting enthalpy equal to or lower than 70 J/g, with a dielectric fluid to obtain an impregnated thermoplastic material; feeding said impregnated thermoplastic material in subdivided solid form to a single-screw extruder; and extruding the impregnated thermoplastic material onto said at least one electrically conductive core, so as to form said at least one thermoplastic electrically insulating layer; whereby said impregnated thermoplastic material is not subjected to any mechanical homogenization step in a molten state. The above process allows to obtain energy cables having a large amount of the dielectric fluid in the electrically insulting layer, e.g. higher than 10 wt%, without showing any morphological defects in the layer itself and any drawbacks in the extrusion process, even when the rotation speed of the extruder screw and therefore the cable production speed are high (e.g. higher than 20 m/min for medium voltage cable).
