Abstract
A high tensile strength transmission cable having a plurality of main compacted strands. The strands surround, and are adjacent to, an uncompacted and moveable core which may form or contain one or more transmission elements. A method for making such a high strength transmission cable includes the steps of compacting the cable formed by a plurality of pre-compacted strands wound around a hard core wire, opening the strands to replace the hard core wire with a soft core containing transmission elements, and then closing the strands.
Claims11
A composite high tensile strength towing cable including:
- an outer cable structure formed of a plurality of unitary strands, said strands being compacted into one another such that the cross-sectional shape of said strands is deformed from an initial circular shape to a final non-circular shape;
- and
- a central fragile non-deformed optical fiber signal transmission element.
A method of manufacturing a high tensile strength transmission cable from a pre-compacted multi-strand cable having a plurality of main strands surrounding a hard core wire including the sequential steps of opening the main strands, removing the hard core wire from the cable, inserting a relatively soft core containing a transmission element, and closing the main strands.
