AAC-All Aluminum Stranded Conductor AS/NZS 1531
AAC AS/NZS 1531
Shape of conductor: circular and sectional
Material: All aluminum conductor
Insulation: N/A
Standard: AS 1531
AAC-All Aluminum Conductor AS/NZS 1531 Overview
The stranded All Aluminium Conductor (AAC) are made up of concentric-lay-stranded aluminum wires only.The conductor may be made up of 7, 19, 37, 61 or more wires in 1, 2, 3, 4 or more layers around a central wire. Each successive layer shall have six more wires than the layer immediately beneath. For a gien cross-sectional area, the conductor becomes more flexible as the number of wires is increased (with a corresponding decrease in size of each wire).
