ASTM Standard 927.2KCM Aluminum Alloy Conductor AAAC Greely
Description of aaac greely
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.
Key Benefits of aaac greely
- High tensile strength as compared to AAAC conductor.
- Higher conductivity as compared to ACSR conductor.
- Better corrosion resistance than ACSR conductor.
