1.1 This specification covers aluminum/single input wire (SIW) stranded conductors made from round or shaped wires for use in covered or insulated electrical conductors. These conductors shall be composed of one or more roller or die compacted layers of helically applied wires (Explanatory Notes 1 and 2).Note 1-For the purposes of this specification, SIW construction is defined as follows: "a stranded conductor design methodology that varies the number of wires within a range of conductor sizes in order to permit that range of conductor sizes to be constructed from a single wire size. See Explanatory Note 2.
1.2 The SI values for density are to be regarded as the standard. For all other properties, inch-pound values are to be regarded as the standard, and the SI units may be approximate.Note 2-The aluminum and temper designations conform to ANSI H35.1. Aluminum 1350 and Aluminum-Alloy 8XXX correspond to Unified Numbering System A91350 and A98XXX, in accordance with Practice E527.
