Aluminum Conductor Alloy Reinforced (ACAR) cable has aluminum wires concentrically stranded around a aluminum alloy core.
Application
ASTM B524 aluminum conductor alloy reinforced (ACAR) for overhead distribution and transmission lines requiring higher mechanical strength than AAC, longer spans, and use as bus-bar in substations. 6201-T81 aluminum alloy core with 1350-H19 aluminum stranded layers. Offers excellent balance of mechanical strength and electrical performance.
Core Strengths
Distribution lines need higher strength than AAC but without steel core weight. Our ACAR uses 6201 alloy core reinforcing aluminum strands—same corrosion resistance as AAC with higher strength and longer span capability. Ideal for substation bus-bars. ASTM B524.
Standard
IEC61089 , ASTM B-524
Construction
☉〉 Outer strands: EC-grade aluminum (high conductivity)
☉〉 Core: Aluminum alloy (e.g., 6201) for mechanical reinforcement
☉〉 Stranding: Concentric layers of aluminum wires around the alloy core
Features
☉〉 High conductivity from outer aluminum strands
☉〉 Good mechanical strength from alloy core (no steel, avoids galvanic corrosion)
☉〉 Lighter than ACSR with similar strength-to-weight ratio
☉〉 Excellent corrosion resistance for coastal or industrial environments
☉〉 Suitable for long-span overhead transmission and distribution
