Title: ELECTRICAL WIRE CONDUCTOR, INSULATING ELECTRICAL WIRE, WIRE HARNESS, AND METHOD FOR MANUFACTURING ELECTRICAL WIRE CONDUCTOR
Abstract:
Provided are: an electrical wire conductor which is composed of aluminum or an aluminum alloy, and the outer diameter of which is controlled to be small while ensuring the required conductor cross-sectional area; and an insulating electrical wire and a wire harness which are provided with the electrical wire conductor. In addition, a method for manufacturing the electrical wire conductor is provided. In the electrical wire conductor in which a plurality of strands comprising aluminum or an aluminum alloy are twisted with each other, the strands are arranged in cross-sections crossing in the axial direction of the electrical wire conductor such that one or a plurality of virtual strands are removed from the outer circumferential section of the virtual cross-section filled with the maximum number of virtual strands having the same diameter as the strands in a circumscribed figure approximated as a regular hexagon. In addition, the electrical wire conductor is configured such that a plurality of child strands, in which a plurality of strands are twisted with each other, are twisted with each other; and the maximum diameter cross-sectional area ratio is set to at least 0.63, as calculated by dividing the cross-sectional area of the electrical wire conductor by the area of a circle having a diameter equal to the maximum value of the outer diameter of the electrical wire conductor.
