All Aluminium-Alloy Conductors (AAAC) is a concentric-lay-stranded conductor consisting of Aluminium-Alloy Wires available in both single layer and multi-layer constructions. AAAC conductor is made from aluminium-magnesium-silicon alloy of high electrical conductivity containing magnesium (0.6-0.9%) & silicon (0.5-0.9%) to give it better mechanical properties after treatment.
This conductor has a minimum conductivity of 52.5% IACS.
All Aluminium-Alloy Conductors (AAAC) can be used in Medium, High and Extra-High voltage transmission lines. AAAC offers better sag performance due to the high strength-to-weight ratio provided by the aluminium-alloy. In addition, AAAC provides a higher corrosion resistance than ACSR conductors. Also, it has higher tensile strength as compared to AAC conductor.
AAAC are of lighter weight and provides higher conductivity as compared to ACSR Conductor. Also, they have better corrosion resistance than ACSR conductor.
This has given AAAC a wide acceptance in the distribution and transmission lines
All Aluminium-Alloy Conductors (AAAC) can be supplied to meet various International Standards as follows:
However, Suraj Cables can also supply a range of alternative designs to meet customer-specified requirements.
