All aluminium alloy conductor (AAAC) contains a small percentage (about 0.6%) of silicon and magnesium elements. It provides several benefits for overhead lines.
Les constructions à 7 et 19 brins conviennent aux réseaux aériens nus de portée moyenne, généralement à basse et moyenne tension. Les constructions à 37 et 61 brins conviennent aux lignes de transport et de sous-transport; leur structure homogène réduit les pertes et améliore la résistance à la corrosion pour une résistance comparable à celle des conducteurs ACSR.
