ELECTRICAL OVERHEAD CABLE ROPE COMPRISING AN INTEGRATED OPTICAL COMMUNICATION LEAD

摘要

PHD 90.006 14.11.1990 Electrical overhead cable rope comprising an integrated optical communication lead. 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) of noble steel, in which at least one optical waveguide (2) is contained. A corrosion of the wire elements of the overhead cable rope is prevented in that the tube (1) of noble steel has applied to it a water-tight coating establishing a continuous electrically conducting connection between the tube of noble steel and the wire elements (14, 15, 16) surrounding it.
