Application

AAAC- The full name: All aluminium alloy conductor. Concentric lay stranded Aluminium Alloy Conductors (AAAC) are made out of high strength Aluminium-Magnesium-Silicon Alloy. AAAC contains a small percentage (about 0.6%) of silicon and magnesium elements. It provides several benefits for overhead lines. AAAC Cable is used as a bare overhead conductor for power transmission and distribution lines, on aerial circuits that require a larger mechanical resistance than AAC, and a better corrosion resistance than ACSR. The sag characteristics and the strength-to-weight ratio of AAAC is better than both AAC / ACSR.

7 and 19 strand construction is suitable for bare overhead reticulation of medium spans, normally at low and medium voltages. 37 and 61 strand construction is suitable for transmission and subtransmission lines where homogeneous construction can reduce line losses and improve corrosion resistance in conductors with similar strength to ACSR types.
