STER- ACSRTM/ AS OR STER-ACSRTM / AW
Aluminium Conductors, Aluminium Clad Steel Reinforced (ACSR/AS or ACSR/AW) are concentrically stranded conductors with one more layers of hard drawn 1350-H19 aluminium wires on Aluminium Clad steel wire core. The core can be single wire or stranded depending on the size.
APPLICATION
Aluminium Clad Steel Reinforced (ACSR/AS or ACSR/AW)
High voltage overhead transmission & distribution lines and coastal regions.
ADVANTAGE
A higher UTS can be achieved by increasing core and higher current carrying capacity by increasing Al content. The mechanical properties of ACSR/AS conductors are similar to ACSR conductors but they offer improved ampacity and resistance to corrosion because of the presence of aluminium clad steel wires in the core. These conductors are better replacement for ACSR conductors where corrosive conditions exist.
