STER-AAC

AAC conductor is also known as aluminium stranded conductor. These conductors consist of several layers of aluminium wires stranded concentrically. AAC are manufactured from electrolytically refined aluminium with a minimum purity of 99.7%

 
Application
 
Aluminium Alloy Conductors

All Aluminium Alloy Conductors - STER-AAC™

All Aluminium Conductor (AAC) have high ratio of electrical conductivity to weight, high flexibility and low UTS. Also the aluminium has low levels of brittleness.

Advantage

All Aluminium Conductors (AAC) are used in low voltage overhead lines in urban areas and in high voltage substation conductoring. They are also used in very cold areas due to low brittleness of aluminium in the MV lines.
