Almelec Cable Aster cable NFC standard All Aluminum Alloy Conductor De 54, 6mm2, 29mm2 148mm2
AAAC Conductor (All Aluminium Alloy Conductor)
Applications
Used as bare overhead conductor for primary and secondary
distribution.The AAAC conductor is designed to get better strength
to weight ratio and offer improved electrical properties, excellent
sag-tension characteristics, and superior corrosion resistance when
compared with ACSR. As compared to a conventional ACSR conductor,
the lighter weight, comparable strength & current carrying
capacity, lower electrical losses and superior corrosion resistance
have given AAAC a wide acceptance in the distribution and medium
& high voltage transmission lines.
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 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 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.
