Application
AAAC- The full name: All aluminium alloy conductor. AAAC contains a small percentage (about 0.6%) of silicon and magnesium elements. It provides several benefits for overhead lines.
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.
