Electrical conductor strand for high voltage overhead lines.

摘要

The electrical cable includes at least one layer of metallic wires (4) around a tube shaped core cable (2). The core cable contains optical fibres (3), has the same outer dia. as the individual wires of the immediately adjacent layer, and is formed as a metal tube. The optical fibres are loosely arranged in the metal tube with an over-length which is greater than 5o/00. The tube may be formed from a metal tape, formed into a tube shaped and welded at the edges.
