This specification covers shaped wire compact concentric-lay-stranded aluminum conductor (AAC/TW) and its component wires for use as overhead electrical conductors. The trapezoidal aluminum wires shall meet the prescribed tensile strength and elongation requirements. Electric-butt welds, electric-butt cold-upset welds, or cold-pressure welds may be made in the individual aluminum wires during the stranding process. Requirements for the lay and construction of the conductor are detailed. The methods of determining the rated strength, breaking strength, mass, and electrical resistance are given. Tests for mechanical and electrical properties of aluminum wires shall be made before stranding. For the purpose of calculating mass per unit length, cross-sections, and the like, the density of aluminum to be taken is specified.
