ASTM B399 BARE ALUMINUM CONDUCTOR AAAC AZUSA BUTTE

APPLICATIONS:

Conductor(AAAC) have been widely used in power transmission lines with various voltage levels, and also used in power lines across great rivers, heavy ice area, and other places special geographical characteristics. The co-nductorhave excellent advantages of high strength, large current carrying capacity and good catenary property as well as wear-resistance, anti-crush and corrosion-proof with simple structure, convenient installation and maintenance, low cost for the line, large transmission capacity.

BENEFITS:

AAAC (All Aluminum Alloy Conductor) conductor cable referred to have higher strength but lower conductivity than pure aluminum. Being lighter, alloy conductors can sometimes be used to advantage in place of the more conventional ACSR; Having lower breaking loads than the latter, their use becomes particularly favourable when ice and win loading are low.
High tensile strength as compared to AAC conductor.
Higher conductivity as compared to ACSR conductor.
Better corrosion resistance than ACSR conductor.

CONSTRUCTION:

Standard 6201T81 high strength aluminum conductors, conforming to ASTM Specification B399, are concentriclay- strandedsimilar in construction and appearance to 1350 grade aluminum conductors. Standard 6201 alloy conductors are similar to other alloy conductors commercially known as Ardival, Aldrey or Almelec. They 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 6201T81 conductors and of the standard ACSRs of the same diameter are approximately the same. Conductors of the 6201T81 alloys are harder and, therefore, have a greater resistance to abrasion than conductors of 1350-H19 grade aluminum.
