Abstract: A conductor assembly of improved physical properties including high tensile strength, crush force resistance and fungi resistance is prepared with at least two individually insulated conductors such as round wires and a cordage product comprising a continuous coherent fibrous article of substantially cylindrical configuration produced from an oriented film composed essentially of a polymeric material, said article being a longitudinally fibrillated fibrous web, the fibroid segments forming said web being in random coherent association. An outer jacket of weatherproofing material surrounds the pair of conductors and the cordage product.

Abstract: An electrical overhead transmission conductor cable having a steel reinforcing core which exhibits improved characteristics and unexpected conductivity above about 64% IACS is manufactured of a steel core covered by at least one stranding layer which is formed of round or trapezoidal shaped wire strands subjected to annealing before heat treatment and drawn and stress-relieved/annealed after stranding is completed, to provide a finished cable which includes an aluminum conductive portion which is dead soft, or "O" temper. The steel core of the cable carries substantially the entire tension load of both the core and conductors when suspended between vertical towers. The overhead transmission cable may be formed of trapezoidal cross section conductors wires for improved vibration performance characteristics.
