A multi-phase cable, the cable including a plurality of conductors for conducting currents of two or more different phases, each phase being associated with one or more conductors and each conductor being associated with one respective phase. Each conductor has a cross-section with at least one dimension that is sized to decrease a skin effect of the conductor at a maximum or nominal operation frequency of the conductor. The conductors are arranged to permit free air cooling of the cable on at least two sides of each conductor, and such that each conductor of a given phase has, as immediate neighbors, only conductors of one or more different phases.

A cable is provided, configured for tandem communication and power transmission. The cable has a plurality of twisted pair conductors and a jacket surrounding said twisted pair conductors. The jacket includes a plurality of either ridges, valleys or both, disposed substantially perpendicular to the longitudinal axis of the cable, the ridges and/or valleys are dimensioned and spaced apart in a manner sufficient to create an air passage when the cable is arranged adjacent to and abutting other cables.

A power supply cable includes: an even number of electric wires that each includes a flexible cooling pipe, an electric conductor that surrounds the cooling pipe, and an insulator that surrounds the electric conductor; a filling disposed around the even number of electric wires; and a sheath that covers the even number of the electric wires and the filling. The electric conductor is a plurality of conductor wires wound around the cooling pipe.

A cable system is provided which is configured with both electric wires and a fluid conduit running through the axial passage of a surrounding flexible sheath of the cable. The system allows for communication of electricity over the wires for electrical circuits and concurrent communication of a fire ignition suppressant fluid or gas through the fluid conduit, to all points in an electric circuit using the cable. One or both of a dye or scent can be included in the ignition suppressant fluid.

Resilient air-cooled induction heating cables are disclosed. An example cable assembly includes: a plurality of conductors in a Litz cable arrangement; a layer of magnet wire insulation over the Litz cable arrangement; an inner silicone dielectric jacket over the layer of magnet wire insulation; and an outer silicone jacket over the inner silicone dielectric jacket.

The present invention discloses a charging cable (1) for transmitting electrical energy, having a cable sheath (2) and at least one electric conductor cable (3) arranged within the cable sheath (2), wherein the charging cable (1) is characterized in that at least one cavity (10) within the charging cable (1), between the cable sheath (2) and the electric conductor cable (3), is filled with a heat conduction medium (11), such that the heat conduction medium (11) is in direct contact with the electric conductor cable (3).

A wire harness includes: a conductive first wiring material wired to a vehicle; and a second wiring material wired to the vehicle in a state where at least a part of the second wiring material is bundled with the first wiring material, and having a flow passage formed therein through which a liquid can flow. With this configuration, the wire harness has an effect of enhancing assemblability to the vehicle, since in a state where the second wiring material having the flow passage therein through which a liquid can flow is bundled with the conductive first wiring material, in addition to the first wiring material, the first wiring material and the second wiring material can be wired to the vehicle together.

The present disclosure provides a cable with cooling function, a current transmission device and an electric vehicle, which belong to the field of current transmission, in which the cable with cooling function includes: a semiconductor cooling module, a conductor and a control module; a cooling end of the semiconductor cooling module is disposed on at least one side of the conductor to absorb heat dissipated from the conductor; the semiconductor cooling module is electrically connected to the control module, and the control module is configured to control an electrical signal supplied to the semiconductor cooling module. The cable with cooling function provided in the present disclosure has the advantages of simple structure, flexible size, reliable performance, no noise and no refrigerant pollution.

Provided are electrical harness assemblies and methods of forming such harness assemblies. A harness assembly comprises a conductor trace, comprising a conductor lead with a width-to-thickness ratio of at least 2. This ratio provides for a lower thickness profile and enhances heat transfer from the harness to the environment. In some examples, a conductor trace may be formed from a thin sheet of metal. The same sheet may be used to form other components of the harness. The conductor trace also comprises a connecting end, monolithic with the conductor lead. The width-to-thickness ratio of the connecting end may be less than that of the conductor trace, allowing for the connecting end to be directly mechanically and electrically connected to a connector of the harness assembly. The connecting end may be folded, shaped, slit-rearranged, and the like to reduce its width-to-thickness ratio, which may be close to 1.
