AAAC Conductor consists of aluminum alloy wires. This Standard specifies the electrical and mechanical characteristics of round wire concentric lay overhead electrical stranded conductors made of combinations of the following aluminum alloy wires:
- aluminum alloy AA6101-T81 in accordance with CAN/CSA-C60104, designated A2;
- aluminum alloy AA6101-T83 in accordance with CAN/CSA-C60104, designated A4;
Features
1.Good corrosion resistance
AAAC has good corrosion resistance because it consists only of aluminum alloy wires.It has better corrosion resistance than ACSR.
2.Better strength to weight ratio
Compared with ACSR,AAAC can get better strength to weight ratio and provide improved electrical properties.
Application
This conductor is mainly used for overhead power transmission. AAAC can be used in Medium and High transmission lines of various voltage levels.Now it has been widely used in power lines across large rivers, heavy ice areas and other special geographical features.
Construction
AAAC conductor involved in this standard is a concentric lay-stranded bare conductor consisting of Aluminum alloy 6101 wires which is available in both single layer and multi-layer constructions.
