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 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 6201-T81 conductors and of the standard ACSR
of the same diameter are approximately the same. Conductors of
the 6201 J81 alloys are harder and, therefore, have a greater
resistance to abrasion than conductors of 1350-H 19 grade
aluminum.
