AAAC Conductor

AAAC Conductor Description

AAAC offers a high strength-to-weight ratio and improved sag performance. It has higher mechanical strength than standard aluminum (AAC) and allows for longer spans. Compared to ACSR (aluminum conductor steel reinforced) conductors, the lack of a steel core provides good conductivity and superior corrosion resistance.

As a result, AAAC conductors are widely used in medium- and high-voltage distribution and transmission lines, particularly in coastal areas or on long-span lines.

AAAC Conductor Construction

Conductor
Aluminium alloy conductor Type AL2 to AL7 as per EN 50183
