APPLICATION
Aluminum Conductors, Aluminum-Alloy Reinforced (ACAR) can be used as bare overhead transmission conductor or primary or secondary distribution conductor. 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
Aluminum Conductors, Aluminum-Alloy Reinforced (ACAR) is a concentric-lay-stranded conductor consisting of stranded aluminum alloy central core with one or more layers of hard drawn stranded aluminum wires. The diameters of all wires are the same. Aluminum and aluminum-alloy wires can be mixed in the same layer.
APPLICABLE STANDARD
Aluminum Conductors, Aluminum-Alloy Reinforced (ACAR) can be supplied to meet various International Standards as follows :
-
International Electrotechnical Commission International Standards-IEC 61089
-
American Standard-ASTM B 524
