ASTM B399 Bare All Aluminum Alloy Conductor AAAC 6201
Application
All Aluminum Alloy Conductor AAAC is used as bare overhead conductor for primary and secondary distribution.
They are designed utilizing a high-strength aluminum alloy to achieve a high strength-to-weight ratio which affords better sag characteristics. Aluminum alloy 6201 gives AAAC higher resistance to corrosion than ACSR conductors.
Characteristics
Standard 6201 alloy conductors were developed to fill the need for an economical conductor for overhead applications requiring higher strength than 1350 grade aluminum conductors ,but without a steel core.
The D.C. resistance at 20℃ of the 6201-T81 conductors and of the standard ACSR 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.
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.
Packing
Delivery lengths are determined from a consideration of such factors as psical drum dimensions, drum weights, span length, handling equipment or the customer’s request.
Packing Materials
Wooden drum, steel-wooden drum, steel drum.
