Aluminum 1350 wires are concentrically stranded and wrapped helically around a central wire. Each successive layer has six wires more than the previous underlying layer. Outer layer is right hand lay and reversed in successive layers. AAC(All aluminum conductor) is the most economical bare overhead conductor due to its lighter weight. It offers easier handing during installation and use of simpler fittings. The conductor is corrosion resistant due to its homogeneous construction.

Bare Conductor Types
(1) all aluminum conductor (AAC)
(2) all aluminum alloy conductor(AAAC)
(3) aluminum conductor steel reinforced (ACSR)
(4) anti-corrosion type ACSR
(5) aluminum conductor aluminum clad steel reinforced(ACSR/AW)
(6)rear earth aluminum conductor steel reinforced(ACSR/RE)
(7)aluminum conductor aluminum alloy reinforced(ACAR)
