Overhead lines, sometimes referred to as aerial conductors, are often specified where there are significant distances to cover and where these cables are best positioned far out of reach. The distances to cover, the environmental conditions it will face, and the location are all factors in specifying the appropriate cable.
The main classifications of bare conductor are AAC (All aluminum conductor), AAAC (All aluminum Alloy Conductor) or ACSR (aluminum conductor steel reinforced). AAC is most commonly found in urban areas with frequent supports and short spans. It is also used in coastal regions where salt in the air can cause corrosion - the all-aluminum wire providing corrosion resistance - and specified for use in the railway industry for OHL electrification. AAAC tend to be specified where greater mechanical resistance is required and where there is a reduced sag characteristic. The ACSR, with its steel reinforcement provides additional strength and where the spans run for larger distances, such as across rivers.
The advantages of AAC, AAAC and ACSR come in their lightweight properties. These overhead lines have no specified voltage rating - it will depend on the type of installation - although the higher corona limit of ACSR makes it beneficial when used with high voltage and extra-high voltage transmission. The overhead line wires are manufactured in accordance with various national standards and can be sized appropriately - including GB/T1179 ASTM B231, ASTM B399, IEC 61089, DIN 48201, BS 215, BS 3242, BS EN 50182 and Spanish standard UNE 21.018. etc.

All Aluminum Alloy Conductors (AAAC)
1. Application
AAAC is mainly used as bare overhead transmission cable and as primary and secondary distribution cable. It is also suitable for laying across basins, rivers and valleys where special geographical features exist.
2. Construction
AAAC cable consists of aluminum alloy wires. The aluminum alloy wires are concentrically stranded.
This section deals with heat-treatable magnesium silicon type aluminum alloys to the applicable International Standard, the electrical and mechanical properties of which all fall within the values suggested by relevant standard.
Conductors to all other recognized specifications can also be supplied. The alloys 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 later, their use becomes particularly favorable when ice and wind loadings are low.
