AAAC conductors are made from high-strength aluminum-magnesium-silicon (AlMgSi) alloy wires, concentrically stranded in one or more layers.
They combine excellent conductivity, corrosion resistance, and high tensile strength, making them suitable for medium and high voltage overhead lines where both mechanical performance and electrical efficiency are required.
The aluminum alloy (typically EN AW-6101 / 6201) offers improved mechanical strength compared to AAC, while maintaining good conductivity and low weight.
