ACAR is made of Aluminium 1350 - H19 wires with Aluminium Alloy 6201 as reinforcement core, having the same role of steel in ACSR, but with much higher ampacity. Its combination result in a good and interesting balance of mechanical strength and electrical performance.
ACAR is used as bare cable for overhead transmission and distribution lines and also as bus-bar in substations where is highly suitable considering the mechanical and electrical characteristics. As comparison with ACSR of same weight, ACAR can offers higher ampacity and mechanical strength.
Reference standards: ASTM B524/524M, ASTM B399/399M, ASTM B230/230M
