Application

Aluminium Conductor Alloy Reinforced (ACAR) is formed by concentrically stranded wires of Aluminium 1350 on high strength Aluminium -Magnesium -Silicon(AlMgSi) alloy core. The number of wires of Aluminum1350 & AlMgSi alloy depends on the cable design. Though the general design comprises a stranded core of AlMgSi alloy strand, in certain cable constructions , the wires of AlMgSi alloy strands can be distributed in layers throughout the Aluminium 1350 strands.When higher capacity and strength for equal weight are prime line considerations, ACAR is the solution over ACSR due to its better strength-to-weight ratio..

Construction

ACAR is a concentric-lay stranded conductor made up of Aluminum 1350-H19 and Aluminum Alloy 6201 strands. While the 6201 Alloy strands usually make up the core with the Aluminum 1350 stranded around them, in some constructions the 6201 Alloy can be distributed in the layers of 1350 Aluminum. The Aluminum Alloy 6201 wires of ACAR preform much like the galvanized steel core of ACSR by mechanically reinforcing the conductor while offering a much higher ampacity. For equal weight, ACAR conductors offer higher strength and ampacity than ACSR conductors.
