ACAR (Aluminum Conductor Alloy Reinforced) refers to an overhead bare conductor with aluminum alloy as the main body and steel core as the reinforcement layer. Its typical structure includes: Conductor layer: 6063 or 6201 aluminum alloy stranding (conductivity ≥ 53% IACS) Reinforced core: galvanized high carbon steel (tensile strength ≥ 1570 MPa) Stranding method: The outer aluminum alloy strands are arranged in concentric circles, with the steel core in the center.
Higher strength and ampacity than ACSR conductors in same weight.
Good corrosion resistance from Aluminum based material, and no Bimetallic corrosion concern.
Excellent and stable transmission under 90 'C and up to 150 'C when overload.
No Hysteresis loss and eddy current loss, energy-saving choice
Almost the same price with ACSR in same length per kilometer.
Excellent and stable transmission under 90 °C and up to 150 °C when overload
1350 H-19 wires concentrically stranded around a 6201-T81 aluminum alloy core.
Some designs have 1350 aluminum wires and 6201 alloy wires intercalated in the same layer.

● ASTM B524
● IEC 61089
● Other National Standards can also be applied
Aluminum conductor alloy (6201) reinforced (ACAR bare conductor) is used as bare overhead transmission and both primary and secondary distribution cable.
A good strength to weight ratio make ACAR bare conductor a preferred choice for lines where both strength and current
arrying capacity are the foremost considerations.
