Frequently Asked Questions (FAQ)
What is AAAC (Aluminum Alloy Conductor)?
AAAC is a concentric-lay-stranded conductor made from high-strength Aluminum-Magnesium-Silicon alloy wires. It is designed to offer a better strength-to-weight ratio and improved electrical properties than traditional conductors.
What does the "Z" twist direction mean for AAAC?
The "Z" twist direction indicates that the outermost layer of the conductor is twisted to the right (clockwise). This is standard for overhead power lines to ensure structural integrity and stability during installation.
How does AAAC compare to ACSR in terms of corrosion resistance?
AAAC provides superior corrosion resistance compared to ACSR because it is constructed entirely of aluminum alloy, eliminating the galvanic corrosion risk associated with the steel core in ACSR.
What are the main applications of AAAC?
AAAC is widely used for overhead power transmission and distribution lines, particularly in coastal areas, river crossings, and industrial environments where high mechanical strength and corrosion resistance are essential.
What factors determine the selection of AAAC code names?
AAAC conductors are selected based on code names which correspond to specific sectional areas (mm²), stranding structures, carrying capacities, and maximum electrical resistance at 20℃.
