American Standard AAAC Conductor Aluminum Alloy 6201-T81 Bare Overhead Cable
APPLICATION
Used as bare overhead conductor for primary and secondary distribution. Designed utilizing a high strength aluminum alloy to achieve a high strength-to-weight ratio; affords better sag characteristics. Aluminum alloy gives AAAC higher resistance to corrosion than ACSR.
Construction
Standard 6201-T81 high strength aluminum conductors, conforming to
ASTM Specification B-399, are concentric-lay stranded, similar in
construction and appearance to 1350 grade aluminum conductors.
Standard 6201 alloy conductors were developed to fill the need for an economical conductor for overhead applications requiring higher strength than that obtainable with 1350 grade aluminum conductors, but without a steel core.
The DC resistance at 20°C of the 6201-T81 conductors and of the standard ACSRs of the same diameter are approximately the same. Conductors of the 6201-T81 alloys are harder and, therefore, have a greater resistance to abrasion than conductors of 1350-H19 grade aluminum.
