The ACSR Bare Conductor (Aluminium Conductor Steel Reinforced) manufactured by Zhongdong Cable is designed for overhead transmission and distribution networks requiring high mechanical strength, long span capability, and reliable electrical performance.
ACSR consists of stranded aluminium wires surrounding a galvanized steel core, combining the excellent conductivity of aluminium with the high tensile strength of steel. This structure makes ACSR suitable for long-distance overhead transmission lines, large-span crossings, and areas exposed to high mechanical loads such as strong wind or heavy ice conditions.

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.
The galvanized steel core increases tensile strength and mechanical stability, allowing ACSR to withstand higher pulling tension and longer spans.
Yes. The reinforced steel core provides better resistance to mechanical stress, making it suitable for harsh weather conditions and long-span overhead lines.
Yes. ACSR is widely used in high-voltage overhead transmission systems due to its combination of conductivity and mechanical strength.
Common constructions include 6/1, 7/1, 18/1, 26/7, and 54/7, where the first number indicates aluminium strands and the second indicates steel core strands.
Typical accessories include suspension clamps, tension fittings, splice joints, connectors, and other overhead line hardware selected according to conductor size and project requirements.
