All Aluminium Conductors (AAC)

All Aluminium Conductors (AAC) is a concentric-lay-stranded conductor consisting of hard drawn 1350 – H19aluminium wires available in both single layer and multi-layer constructions.

AAC conductor is also known as Aluminium Stranded Conductor. It is manufactured from electrolytically refined aluminium, with a minimum metal purity of 99.7% The EC grade Alloy Conductor has a minimum conductivity of 61.2% IACS.

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 aluminium has made AAC a conductor of choice in coastal areas. Because of its relatively poor strength to weight ratio, AAC has limited use in transmission lines and rural distribution where long spans are required.

AAC (All Aluminium conductor) is the most economical bare overhead conductor due to its lighter weight and it offers easier handling during installation and use of simpler fittings. The wire is corrosion resistant due to its homogeneous construction.
