1.1 This specification covers concentric-lay-stranded conductors made from round aluminum-alloy 6201-T81 hard: solution heat treated, cold worked, and then artificially aged wire and round zinc-coated, aluminum-coated, or aluminum-clad steel core wire for use as overhead electric conductors (Explanatory Notes 1 and 2).Note 1-All values are stated in SI units. No inch-pound equivalents are presented, nor is an inch-pound companion specification proposed. Note 2-The alloy and temper designations conform to ANSI H35.1. Aluminum alloy 6201 corresponds to Unified Numbering System alloy A96201 in accordance with Practice E527. Note 3-It is proposed that references to inch-pound documents be changed to metric companions of applicable documents as they are developed, possibly requiring minor changes in some values in this specification.
