Product Description AAAC, or All Aluminium Alloy Conductor, is used as a bare overhead conductor for power transmission and distribution lines. AAAC conductor are made out from aluminum-magnesium-silicon alloy of high electrical conductivity (min 53% IACS) containing magnesium (0.6-0.9%) & silicon (0.5-0.9%) to give it better mechanical properties after treatment. AAAC conductors are made out of aluminum alloy 6201. AAAC conductor has a better corrosion resistance and better strength to weight ratio and improved electrical conductivity than ACSR conductor on equal diameter basis. Standards: ASTM - B 399 Metric Units ASTM - B 231 TS IEC 1089 DIN 48201 BS 215 UNE 21.018 Key Benefits: High tensile strength as compared to AAAC conductor. Higher conductivity as compared to ACSR conductor. Better corrosion resistance than ACSR conductor.
