High Voltage HV AAC Aluminum Conductors For Power Transmission
AAC Aluminum Conductors are made up of concentric-lay-stranded aluminium wires only.
The conductor may be made up of 7, 19, 37, 61 or more wires in 1, 2, 3, 4 or more layers arounda central wire. Each successive layer shall have six more wires than the layer immediately beneath.For a given crosssectional area, the conductor becomes more flexible as the number of wires is increased(with a corresponding decrease in size of each wire).
