SURAL AAAC bare conductor meetsor exceeds the following ASTM specifications:

B-398 Aluminum Alloy 6201-T81 Wire for Electrical Purposes
B-399 Concentric-Lay-Stranded 6201 J81 Aluminum Alloy Conductors

Standard 6201-T81 high strengthaluminum conductors, conforming to ASTM Specification B-399, areconcentric-lay-stranded, similar in construction and appearance to 1350 gradealuminum conductors. Standard 6201 alloy conductors are similar to otheralloy conductors commercially known as Ardival, Aldrey or Almelec. They weredeveloped to fill the need for an economical conductor for overheadapplications requiring higher strength than that obtainable with 1350 gradealuminum conductors, but without a steel core.

The DC resistance at 20"C of the 6201-T81conductors and of the standardof the same diameter are approximately thesame. Conductors of the 6201 J81 alloys are harder and, therefore, have agreater resistance to abrasion than conductors of 1350-H 19 grade aluminum.
