Strength | About twice that of aluminium 1350(EC) | ||||||
Weight | Approximately 20% lighter than ACSR conductor of equal diameter | ||||||
Corrosion resistance | It has a high resistance to atmospheric corrosion which is suitable for coastal and industrial areas. | ||||||
Surface hardness | AAAC's surface is significantly harder than aluminium 1350. It is less liable to damage during installation which is an important advantage of EHV transmission lines where corona and radio interference is a major consideration. | ||||||
Termination | Much simpler jointing accessories required compared to ACSR | ||||||
AC Resistance | AAAC is a non-magnetic material. It does not exhibit the magnetic core losses found in ACSR |
