All Aluminium Alloy Conductors (AAAC)
High-strength, corrosion-resistant aluminum overhead conductor with excellent conductivity, ideal for overhead power transmission and distribution.
What are All Aluminium Alloy Conductors ?
AAAC (All Aluminium Alloy Conductor) are stranded conductor made from aluminum alloy, offering high strength, corrosion resistance, and good conductivity for overhead transmission lines.
AAAC conductors are composed of high-strength aluminium alloy strands, providing an excellent balance of mechanical strength, enhanced corrosion resistance, and reliable electrical conductivity. Manufactured from premium aluminium-magnesium-silicon alloy and conforming to IS 398 (Part 4), these conductors are well-suited for overhead transmission and distribution systems, particularly in coastal, industrial, and high-pollution environments where durability is critical.
At Mahavir Transmission Limited, AAAC conductors are manufactured under rigorous quality control protocols using advanced wire-drawing and precision stranding technologies. This ensures consistent performance, accurate dimensional properties, and long operational life even under demanding service conditions.
With a superior strength-to-weight ratio, AAAC conductors support longer span lengths with reduced sag, making them an ideal choice for modern power infrastructure, rural electrification, and installations across varied and challenging terrains.
