摘要： A method for manufacturing an aluminum wire is provided. The aluminum wire includes an inner-layer conductor having one or a plurality of inner-layer alloy wires including aluminum and an outer-layer conductor having a plurality of outer-layer alloy wires including aluminum and provided on the inner-layer conductor. The method includes an outer-layer twisting step of twisting, over the inner-layer conductor, the outer-layer alloy wires provided on the inner-layer conductor, and an outer-layer rotational compression step of compressing the outer-layer alloy wires twisted in the outer-layer twisting step while being rotated in the same direction as the direction of the twisting in the outer-layer twisting step.

摘要： An electric wire conductor is excellent in space saving and flexibility and is less likely to concentrate a load on specific elemental wires, and a covered electric wire and a wire harness contain the electric wire conductor. The electric wire conductor contains a wire strand containing a plurality of elemental wires twisted together. The wire strand has a sector-shaped part in which a cross-section intersecting an axial direction of the wire strand contains either a single edge or two edges touching each other at an apex, and an outward curve connecting the ends of the single edge or the two edges. In the sector-shaped part, the elemental wires having deformation ratios from a circle lower at an outer peripheral part facing an outer periphery of the sector-shaped part than at a center part of the sector-shaped part located inside the outer peripheral part in the cross-section intersecting the axial direction.

摘要： The present invention relates to electrical conductors for electrical transmission and distribution with pre-stress conditioning of the strength member so that the conductive materials of aluminum, aluminum alloys, copper, copper alloys, or copper micro-alloys are mostly tension free or under compressive stress in the conductor, while the strength member is under tensile stress prior to conductor stringing, resulting in a lower thermal knee point in the conductor.

摘要： A composite stranded wire conductor includes a core bunched strand wire, first bunched strand wires mainly wound at a first main twist pitch around the core bunched strand wire, and second bunched strand wires wound at a second main twist pitch around first bunched strand wires. In the core bunched strand wire, metal wires are primary twisted in a first direction. In each of the first bunched strand wires, metal wires are primary twisted in a second direction opposite to the first direction. In each of the second bunched strand wires, metal wires are primary twisted in the first direction. A pitch ratio obtained by dividing the second main twist pitch by the first main twist pitch is 1.00 or more and 2.44 or less.
