1、Designation: B524/B524M 99 (Reapproved 2011)Standard Specification forConcentric-Lay-Stranded Aluminum Conductors, Aluminum-Alloy Reinforced (ACAR, 1350/6201)1This standard is issued under the fixed designation B524/B524M; the number immediately following the designation indicates the yearof origina
2、l adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval.A superscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers concentric-lay-stranded con-ductors made
3、 from round aluminum 1350-H19 (extra hard)wires and round aluminum-alloy 6201-T81 (hard: solution heattreated, cold worked, and then artificially aged) core wires foruse as overhead electrical conductors (Explanatory Note 1).NOTE 1The aluminum, alloy, and temper designations conform toANSI H35.1/ANS
4、I H35.1M. Aluminum 1350 and Alloy 6201 corre-spond to unified numbering system A91350 and A96201, respectively, inaccordance with Practice E527.1.2 The values stated in inch-pound units are to be regardedas standard. The values given in parentheses are mathematicalconversions to SI units that are pr
5、ovided for information onlyand are not considered standard.1.2.1 For density, resistivity and temperature, the valuesstated in SI units are to be regarded as standard.1.3 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of
6、the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.
