AAAC Conductor consists of aluminum alloy wires.
The bare-core stranded conductor is made of heat treated aluminium-magnesium-silicon alloy wires.
Two types of aluminium-magnesium-silicon alloy wires have different mechanical and electrical properties. The two types are designated Type A and Type B respectively.
Conductors are made of combinations of the following wires:
- aluminium alloy type B as per IEC 60104, designated A2;
- aluminium alloy type A as per IEC 60104, designated A3.
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
Aluminum alloy wires, concentrically stranded.
