AAC-All Aluminum Conductor
Concentric lay stranded Aluminum Conductor ( AAC) is made up of one or more strands of hard drawn 1350 aluminum alloy. These conductors are used in low, medium and high voltage overhead lines. AAC has seen extensive use in urban areas where spans are usually short but high conductivity us required. The excellent corrosion resistance of aluminum has made AAC a conductor of choice in coastal areas. Because of its relatively poor strength to weight ratio, AAC had limited use in transmission lines and rural distribution because of long spans utilized.
This all aluminum conductor is a kind of aluminum product made through stranding aluminum wires. It is used for the electricity distribution lines with short span length and small load-carrying capability of the pole. The AAC provides reliable performance for overhead power transmission and distribution lines. This standard covers hard drawn circular aluminum wires for electric purposes to be used as component wires of hard drawn aluminum stranded cables and aluminum conductor steel reinforced
AAC is a concentric-lay-stranded conductor consisting of aluminum alloy 1350-H19 wires available in both single-layer and multi-layer constructions
