Applications

They are used mostly as bare aerial conductors for primary and secondary energy distribution. They are manufactured with high strength aluminum alloy to achieve a high weight-resistance ratio, as well as good bending capacity.

(1) AAAC conductors are widely used in overhead distribution lines and transmission lines near coasts where corrosion is a constant problem.

(2) Aluminum alloy conductors are used as substitutes for single-layer ACSR conductors to reduce energy loss in the distribution and transmission lines. They can save the production cost of 5-8%.

(3) They have a greater resistance, but also a lower conductivity than the aluminum conductor, which is also lighter. Consequently they are a good replacement for conventional ACSR cables.

Characteristics

Aluminum alloy conductors have a number of advantages over ACSR or AAC cables (aluminum conductors).

They operate with a lower energy loss than the ACSR conductors (They avoid the inductive effect of the steel core of the ACSR cables).

■The required accessories are simpler than for ACSR conductors.

■Corrosion resistance in conductive environments is better in ACSR cables.

■The force and bending are approximately the same as that of ACSR conductors 6/1 and 26/7.

■The external diameters are the same as for the ACSR conductors, which makes the exchange of accessories possible.

■Higher resistance to abrasion than that of 1350 aluminum cables and ACSR conductors.

■Breakdown voltage higher than that of AAC conductors.

■Higher conductivity than ACSR conductors.
