TAAAC Conductor (Thermally Activated Aluminum Alloy Conductor) is an advanced aluminum alloy overhead conductor designed for high-temperature applications in power transmission lines. With its heat-resistant aluminum alloy composition, TAAAC Conductor provides low-sag performance, making it ideal for modern smart grid infrastructure. Compared to traditional conductors like ACSR and ACSS, TAAAC offers superior mechanical strength, corrosion resistance, and high conductivity for energy-efficient power transmission.TAAAC conductor is used in the transformation of old lines, urban network capacity transformation, substation, power plant construction and general lines.
TAAAC is a concentrically stranded conductor composed of thermal resistant aluminum alloy wires (TAL).
