AAAC / All Aluminum Alloy Conductor

All aluminum alloy Conductor (AAAC) Definition: All strands are stranded wires of aluminum alloy wire.Since it was put into production in 2008, the product quality has been relatively stable, the production efficiency is high, and the market share is high in the international market.

AAAC has high strength and good sag characteristics. AAAC is 21% ~ 26% lighter than ACSR, and its deformation tension is 21% ~ 23% lower. The tensile strength of AAAC is 1.7 ~ 1.8 times that of ordinary conductor. The ratio of total breaking force to weight per unit length of high strength all aluminum alloy stranded wire without strip core is more than 10km, which is higher than that of reinforced steel cored wire in the past (about 9km). Therefore, it can effectively reduce the height of the tower, or increase the erection spacing, and reduce the project investment.

Advantage:

1. AAAC has large mechanical resistance than AAC which permits its use as a bare overhead conductor on aerial circuits for power transmission and distribution lines.
2. AAAC has better sag characteristics and strength to weight ratio as compared to AAC.
3. AAAC weight per unit and resistance is also lower which gives it advantage over the ACSR. Also, AAAC conductor has better corrosion protection than ASCR conductors.

According to the French experience, the span is increased from 350m-400m to 550m, and the construction investment can be saved by 5% – 8% if the high-strength all aluminum alloy wire is used instead of ACSR in the new line;

High conductivity, large transmission capacity and small line loss. The conductivity of AAAC is 6% ~ 11% higher than that of corresponding ACSR, with lower AC impedance and 3% less line loss. When the ACSR is replaced by AAAC, the capacity of the transmission line can be increased without any modification or enhancement of the original supporting tower;

Good corrosion resistance. The steel strand in ACSR has the problem of electric corrosion in operation, especially in the polluted area. The aluminum alloy monofilament used by AAAC is more corrosion-resistant than ordinary aluminum, and AAAC has no steel core, so there is no electric corrosion problem of steel wire;

The surface is resistant to damage. The hardness of the aluminum alloy wire is twice that of the aluminum wire, which can reduce the surface scratch of the wire, improve the construction quality, and reduce the corona loss and radio interference level;

Good creep resistance, high elongation and high temperature characteristics. According to the standard value, the elongation of aluminum wire is 2 times of that of aluminum wire (1.5%), and the actual test value can reach 7% ~ 8%. It has excellent overload capacity and fatigue characteristics. At high temperature, the strength loss is small, and the high temperature operation plays the role of artificial aging, increasing the conductivity by 2% ~ 5%;

Good connectivity, simple and convenient connection. Large torque can be used without considering the cold deformation of conductor;

Compared with ACSR, AAAC has no steel core and is of the same material. Its recyclability is greatly improved and its recycling rate is high, which is beneficial to environmental protection.
