AAAC Bare Overhead Conductors Aluminium Alloy 6201 For Power Transmission Line
ASTM B399 AAAC Conductor Aluminium Alloy 6201 Used in Power Transimission Line
1.Application
AAAC conductors are designed to get better strength to weight ratio and offer improved electrical properties, excellent sag-tension characteristics, and superior corrosion resistance when compared with ACSR. As compared to a conventional ACSR conductor, the lighter weight, comparable strength & current carrying capacity, lower electrical losses and superior corrosion resistance have given AAAC a wide acceptance in the distribution and medium & high voltage transmission lines.
