The AAAC Bare Conductor (All Aluminium Alloy Conductor) manufactured by Zhongdong Cable is designed for overhead power transmission and distribution networks requiring higher mechanical strength, excellent corrosion resistance, and reliable long-term outdoor performance.
AAAC is made entirely of aluminium alloy wires stranded concentrically to form a lightweight bare conductor. Compared with AAC, AAAC provides improved tensile strength and better resistance to environmental conditions while maintaining good electrical conductivity. It is widely used in overhead distribution and transmission systems, especially in coastal, industrial, and high-humidity areas.

AAC is made of pure aluminium and offers the highest conductivity with lower mechanical strength, suitable for short and medium-span distribution lines. AAAC uses aluminium alloy strands, providing higher tensile strength and better corrosion resistance. ACSR combines aluminium strands with a steel core, offering the highest mechanical strength for long-span transmission lines and areas with high mechanical loads.
AAAC provides higher mechanical strength and better corrosion resistance while maintaining good conductivity, making it suitable for areas requiring improved line reliability.
Yes. The aluminium alloy construction provides excellent resistance to corrosion and is commonly used in coastal and high-humidity areas.
In some applications, yes. AAAC can be used when corrosion resistance and reduced weight are important, while ACSR is preferred where maximum tensile strength is required.
Typical accessories include suspension clamps, tension clamps, connectors, and other overhead line fittings selected according to conductor size and installation conditions.
