All Aluminum-Alloy Conductors (AAAC) is a concentric-lay-stranded conductor consisting of aluminum-alloy wires available in both single layer and multi-layer constructions.

They were developed to the need of economical conductor for overhead applications requiring higher strength than that of 1350 grade aluminum conductors, but without a steel core.

All Aluminum-Alloy Conductors (AAAC) can be used in Medium, High and Extra-High voltage transmission lines. AAAC offers better sag performance due to the high strength-to-weight ratio provided by the aluminum-alloy.In addition, AAAC provides a higher corrosion resistance than ACSR conductors .

All Aluminum Alloy Conductors(AAAC) can be supplied to meet various international standards as follows:

ASTM B399/ASTM B231 ,IEC 61089,BS EN 50182 DIN 48201,NFC 34,CSA C49 etc

Huaxing cable can also supply a range of alternative designs to meet customer-specified requirements.

Application :

Used as bare overhead conductor for primary and secondary distribution. Designed for utilizing a high-strength aluminum-alloy to achieve a high strength-to-weight ratio; affords good sag characteristics. 

(1)AAAC conductors are extensively used for overhead distribution and transmission lines adjacent to ocean coastlines where there can be a problem of corrosion in the steel of an ACSR construction.

(2)The aluminum alloy conductors are used in replace of single-layer ACSR conductors to reduce power loss in overhead distribution and transmission lines,when replacing the aluminum conductor steel reinforced , the AAAC can save 5-8% of the construction cost.

(3)AAAC referred to have higher strength but lower conductivity than pure aluminum. Being lighter, alloy conductors can sometimes be used to replace the conventional ACSR.
