70mm2 overhead bare copper cable

70mm2 overhead  bare copper cable .

Applications:

Used as bare overhead conductor for primary and secondary distribution. Designed utilizing a high strength aluminum alloy to
achieve a high strength-to-weight ratio; affords better sag characteristics. Aluminum alloy gives AAAC higher resistance to
corrosion than ACSR.

Specifications:

AAAC bare conductor meets or 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

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 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
