A composite cable includes a plurality of power lines, one signal line unit, and a sheath collectively covering the plurality of power lines and the one signal line unit. The signal line unit includes a plurality of pairs of signal lines, and an inner sheath covering a first assembled article. The first assembled article is formed by arranging the signal lines to be paired at each pair of opposing vertices of a polygon with an even number of vertices in a cross-section perpendicular to a longitudinal direction of the signal line unit and twisting all the signal lines together.

The signal line unit includes a plurality of pairs of signal lines, and an inner sheath covering a first assembled article. The first assembled article is formed by arranging the signal lines to be paired at each pair of adjacent vertices of a polygon with an even number of vertices in a cross-section perpendicular to a longitudinal direction of the signal line unit and twisting all the signal lines together. A twisting direction of a second assembled article formed by twisting the plurality of power lines and the one signal line unit together is different from a twisting direction of the first assembled article.

An intelligent motion sensing cable is disclosed, where a motion sensor that is included in the cable can detect cable motion. The cable can then use this detected motion to intelligently control a charge signal delivered by the cable to a connected electronic device and/or generate data indicative of customer interactions with a connected electronic device.

The invention concerns a subsea umbilical comprising an electrical conductor (2) and/or a fluid pipe, and an outer sheath (7) surrounding the electrical conductor (2) and/or the fluid pipe. The umbilical (1, 20, 21, 25, 30, 40, 51, 60) further comprising a plurality of deformable rods (3a, 3b, 15, 23a, 23b, 26a, 27a, 26b) evenly distributed between the electrical conductor (2) and/or the fluid pipe, and the outer sheath (7) for radial load protection of said electrical conductor (2) or fluid pipe.

The present invention discloses a mobile dedicated cable for a medical Computed Tomography (CT) bed, comprising an inner sheath layer, a first Teflon® belt, a signal cable layer, a second Teflon® belt, a braided layer and an outer sheath layer, which are coaxially arranged from inside to outside in sequence. The inner sheath layer comprises a PVC filling strip wrapped by the first Teflon® belt, and a plurality of bulletproof filaments arranged in the center of the PVC filling strip. The signal cable layer comprises a plurality of signal lines evenly arranged therein, each of which are circumscribed with the first Teflon® belt and the second Teflon® belt, and with two signal lines adjacent thereto. The cable of the invention has improved flexibility and working life, thereby being suitable for the medical CT bed.

A power cable (1) for an electric submersible pump (ESP) system, and systems and methods thereof are described herein. The power cable (12) is a weight-bearing three-phase power cable comprising a core (8) having an outer diameter and comprising three insulated conductors (2) substantially embedded in a polymeric bedding (3); and a multi-layered armor comprising an inner steel-based continuous tube (4) surrounding and in direct contact with the core (8), and an outer steel-based continuous tube (5) surrounding and in direct contact with the inner steel-based continuous tube (4). The inner steel-based continuous tube (4) and the outer steel-based continuous tube (5) are mechanical congruent with each other as a result of a roll reducing technique.

In one embodiment, a cable includes a data transmission path disposed about an axial center of the cable and a power transmission path sheathing the data transmission path. The power transmission path includes a power layer and a ground layer, where the power transmission path is characterized by a distributed impedance having at least one frequency dependent impedance characteristic. In some implementations, ground layer shields the data transmission path from electromagnetic interference. In some implementations, the frequency dependent impedance characteristic of the power transmission path is characterized by a capacitance value that satisfies a capacitance criterion at frequencies above a first frequency level. In some implementations, the frequency dependent impedance characteristic of the power transmission path is characterized by an inductance value that satisfies a first inductance criterion at frequencies above a first frequency level.

A multi-core flat cable for a vehicle includes a sheath covering two power wires and at least two signal wires. A pair of the signal wires is twisted and is configured as one twisted pair of signal wires. On a section perpendicular to a longitudinal direction, a ratio (long-axis dimension/short-axis dimension) of a long-axis dimension to a short-axis dimension is equal to or greater than 1.8.

A composite cable that enables to easily restrain falling-off of separator dust at the time of peeling off a sheath, in comparison with composite cables in the conventional art. The composite cable includes a plurality of wires, a separator that covers the outer circumference of the plurality of wires all together, a sheath that covers the outer circumference of the separator, and an inclusion that is interposed between the separator and the sheath. The separator has a base layer composed of a polymer and an adhesive layer formed on the surface of the base layer on the inclusion side. In the composite cable, the adhesive layer is adhered to the inclusion.

Induction heating extension cables including control conductors are disclosed. An example cable assembly includes: a first plurality of conductors in a Litz cable arrangement; an outer protective layer configured to protect the plurality of conductors from physical damage; and a second plurality of conductors that are electrically isolated from the first plurality of conductors and are protected by the outer protective layer from physical damage.
