ACSR conductors are made up of concentrically stranded conductor with single or multiple layers of hard drawn aluminium wire on galvanized steel wire core which are coated with zinc of Class A / Class B Coating. The core can be single wire or stranded depending on the size of the conductor. Additional corrosion protection is available through the application of grease to the core.

These are made from high strength Aluminium-Magnesium-Silicon Alloy. Because of its construction, it has better strength to weight ratio, has lower electrical losses and superior corrosion resistance. As a result, it has gained wider acceptance in the distribution and transmission of medium and high voltage lines in comparison to AAC and ACSR.

AL-59 alloy conductors are manufactured from Al-Mg-Si rods. The conductor comprises of an inner core and concentrically arranged strands forming the outer layers of the conductor. These are Low resistance High Conductivity alloy conductors with superior characteristics than ACSR/AAAC which has made it widely acceptable in transmission sector.
