A high-power low-resistance electromechanical cable constructed of a conductor core comprising a plurality of conductors surrounded by an outer insulating jacket and with each conductor having a plurality of wires that are surrounded by an insulating jacket. The wires can be copper or other conductive wires. The insulating jacket surrounding each set of wires or each conductor can be comprised of ethylene tetrafluoroethylene, polytetrafluoroethylene, polytetrafluoroethylene tape, perfluoroalkoxyalkane, fluorinated ethylene propylene or a combination of materials. A first layer of a plurality of strength members is wrapped around the outer insulating jacket. A second layer of a plurality of strength members may be wrapped around the first layer of a plurality of strength members. The first and/or second layer of strength members can be made of single wires, synthetic fiber strands multi-wire strands, or rope. If either or both layers are made up of synthetic fiber, then the synthetic fibers may be surrounding and encapsulated by an additional insulating and protective layer.

A cable, which may be produced by the method described herein, comprises a cable with a core jacket comprising a predetermined cable length where the core jacket comprises a thermoplastic material comprising a memory characteristic which changes based on temperature, a set of core components, disposed within the core jacket, which comprise the predetermined length, and a strength member disposed within the core jacket intermediate the core components and the core jacket. The strength member comprises a selectively activated pre-impregnated uncured synthetic material adapted to be cured while in production, the strength member comprising a length substantially equal to the predetermined length.

Disclosed is a non-steel high strength data transmission cable having a strength member (5) and a core (1). The high strength data transmission cable includes a length of a core-cable (10), the length of core-cable (10) includes core (1) plus at least one fiber-optic conductor (2) that is: (i) disposed in a helical shape; and (ii) completely encased in a solid, flexible material. Also disclosed is a process for making a high strength data transmission cable. The high strength data transmission cable is capable of being wound on a winch under tensions and surging shocks experienced by a fishing trawler, and provides high quality data signal transmission and resolution so as to permit use for transmitting data during fish trawl operation from high-resolution sonars used to monitor fish caught.

A wired kernmantle cord comprises a single continuous length of 20-30 AWG solid, stranded, or braided metal wire coaxially placed in the center of a bundle of seven nylon yarns. The seven yarns each comprise three twisted nylon fibers. The metal wire and the seven yarns thus form a kern that is sheathed inside a woven, braided outer mantle of nylon. The mantle sheathing is woven densely and tightly enough to keep the kern from appearing or working through, and it provides electrical insulation for the metal wire, and weather and abrasion resistance and other environmental protection for the whole.

A wireline cable includes an electrically conductive cable core for transmitting electrical power. The wireline cable further includes an inner layer of a plurality of first armor wires surrounding the cable core and an outer layer of a plurality of second armor wires surrounding the inner layer, wherein a diameter of the outer layer of the plurality of second armor wires is smaller than a diameter of the inner layer of the plurality of first armor wires.

Braided composite yarns including one or more functional components such as conductors and one or more structural components such as para-aramid fibers, and methods of manufacture therefor. Bundles of at least one functional component and at least one structural component undergo simultaneous parallel winding under tension onto a single bobbin prior to braiding, thus reducing the mechanical loading forces on the functional components in the final yarn. The yarns can be engineered with application-specific electrical, electronic, electromagnetic, or physical properties that enable their use as electronic components or sensors, and attached to or incorporated into active textiles and composite substrates. Such yarns can be used to measure elongation, compression, twist, and other properties of a braided object in which they are incorporated.

A production method for a headline sonar cable characterized by steps of: a. providing a first strength member (14); b. coupling to strength member (14) a conductor (122); c. forming a layer of polymeric material about the combination of strength member (14) and conductor (122) while ensuring that the conductor remains slack; d. forming a flow shield around the layer of polymeric material, thus forming an elongatable internally located conductive structure; and e. braiding a strength-member jacket layer (52) of polymeric material around the elongatable internally located conductive, structure while ensuring that the conductor is slack when surrounded by the jacket layer (52). For another embodiment, an optical fibre is wrapped around the exterior of the layer of polymeric material within which is enclosed a braided conductor formed about the first strength member (14). Other embodiments employ further thermo-plastic layers and further sheaths and further conductors.
