ABSTRACT:
The invention relates to an electrical overhead cable rope comprising an integrated optical communication lead (13), in which metallic wire elements (14, 15, 16) surround a tube (1) or noble steel, in which at least one optical waveguide (2) is contained. Corrosion of the wire elements of the overhead cable rope is prevented by providing a tube (1) of noble steel having applied to it a water-tight coating which establishes a continuous electrically conducting connection between the tube of noble steel and the wire elements (14, 15, 16) surrounding it.
