AAAC(All Aluminum Alloy Conductor)

All Aluminium Alloy Conductor (AAAC) overhead Conductor

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.

All Aluminium Alloy Conductor (AAAC) overhead Conductor

Application:

The conductor is 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..

Standard:

IEC 1089 A2, IEC 1089 A3, ASTM B 399, BS 3242,DIN 48201

Physical Contents of Alluminium Alloy :

Density : 2.70 kgm/dm3 at 20°C

Coefficient of Linear Expansion : 23 x 10-6 / °C

Resistivity : 0.0326 Ohms mm2/m at 20°C

Constant Mass Temperature Coefficient (a) : 0.00360/ °C
