AAAC Bare Conductor for Overhead (electric cable)

Description

AAAC, or All Aluminium Alloy Conductor, is used as a bare overhead conductor for power transmission and distribution lines. AAAC conductor are made out from aluminum-magnesium-silicon alloy of high electrical conductivity (min *3% IACS) containing magnesium (0.**0.9%) & silicon (0.**0.9%) to give it better mechanical properties after treatment. AAAC conductors are made out of aluminum alloy ***1. AAAC conductor has a better corrosion resistance and better strength to weight ratio and improved electrical conductivity than ACSR conductor on equal diameter basis. 
Standards: ASTM - B **9 Metric Units 
ASTM - B **1 
TS IEC ***9 
DIN ****1 
BS **5 
UNE *1.**8 

Key Benefits: 

High tensile strength as compared to AAAC conductor. 
Higher conductivity as compared to ACSR conductor. 
Better corrosion resistance than ACSR conductor.
