AAAC Conductors - An Overview

AAAC or All Aluminium Alloy Conductors are increasingly used in transmission linesinstead of ACSR Conductors. AAAC conductors have better mechanical properties and improved resistance to Corrosion as compared to ACSR conductor. 

AAAC Conductors are made from an alloy of Aluminium, Magnesium  and Silicon.  The absence of the steel core which is prone to corrosion makes AAAC conductors as ideal for use in coastal and industrial area. 

AAAC conductors have increased current carrying capacity, lower power loss and higher thermal stability limit.   Besides, AAAC conductors have higher strength-to-weight ratio Which reduce the cost of supports. 

In areas which have poor security, ACSR Conductors are prone to theft, particularly low voltage lines. AAAC conductors are not attractive to thieves as there are no alternative applications for the alloy which is made of aluminium, magnesium and silicon.      

This conductor is manufactured from Aluminium-Magnesium-Silicon alloy of high electrical conductivity containing enough magnesium silicate to give it better mechanical properties. AAAC conductors have better corrosion resistance and better strength to weight ratio and improved electrical conductivity than ACSR Conductors on equal Diameter basis.
