Applications

Used as bare overhead conductor for primary and secondary distribution.

Designed utilizing a highstrength 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

SURAL 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 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.

Product Description 

AAAC (All Aluminum Alloy Conductor) 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 loadings are low.

We can supply this conductor according to different recognized standards, 

such as BS EN50182, IEC61089, ASTM B399DIN 48, 

customer special specification also can be satisfied.
