STER-ACAR

Aluminium Conductor Alloy reinforced (ACAR) is formed by concentrically stranded wires of Aluminium 1350 and high strength Aluminium-Magnesium-Silicon (AIMgSi) alloy core. The number of wires of each depends on the cable design. The typical design comprises a stranded core of AIMgSi alloy strands but in certain cable constructions, the wires of AIMgSi alloy strands can be in layers throughout the Aluminium 1350 strands

Aluminium Conductors Alloy Reinforced

Aluminium Conductors Alloy Reinforced - STER - ACAR™

Aluminium Conductors Alloy Reinforced (ACAR) are extensively used for overhead distribution and transmission lines.

Advantage

ACAR has better mechanical and electrical properties as compared to an equivalent ACSR, AAC or AAAC. A very good balance between mechanical & electrical properties makes ACAR the best choice where ampacity, strength and low weight are main consideration for line design. ACAR offers higher strength and ampacity than ACSR of same weight. A higher UTS and current carrying capacity can be obtained by increasing aluminium alloy and aluminium content respectively.
