Standard Specification for Compact Round Stranded Aluminum Conductors Using Single Input Wire Construction
This specification covers compact round stranded aluminium conductors using single input wire construction. Joints may be made in any of the wires of any stranding by electric-butt welding, cold-pressure welding, or electric-butt, cold-upset welding. No joint or splice shall be made in a stranded conductor as a whole. The rated-strength and breaking-strength requirements of conductor are presented in details. Tests for the mechanical and electrical properties of wire composing the conductor shall be made before, but not after, stranding unless otherwise agreed upon by the manufacturer and the purchaser as provided by the reference materials.
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 wires or cables. These conductors shall be composed of one or more roller or die compacted layers of helically applied wires (Explanatory Note 1, Explanatory Note 2, and Explanatory Note 3).
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.2.1 For density, resistivity, and temperature, the values stated in SI units are to be regarded as standard.
Note 1: 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.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
