A power or data transmission cable comprising:
- a cable core extending along a longitudinal direction;
- a water barrier in form of a metallic foil folded around the cable core along the longitudinal direction with overlapped edges, the overlapped edges being bonded to one another by a bonding layer made of an inorganic material.
A process for manufacturing a power or data transmission cable comprising:
- providing a transmission cable core extending along a longitudinal direction;
- providing a metallic foil made of a metal having a melting temperature, the metallic foil comprising longitudinal edges;
- folding the metallic foil around the transmission cable core along the longitudinal direction;
- applying a solder paste on at least one of the longitudinal edges, the solder paste having a sintering temperature lower than the melting temperature of the metal of the metallic foil;
- overlapping the two longitudinal edges of the metal foil so as to bring them in contact via the solder paste;
- heating at least the overlapped longitudinal edges up to the sintering temperature of the solder paste to form a bonding layer binding the longitudinal edges and yielding a water barrier.
