Overhead Conductors

3M™ ACCR’s secret is the unique material used in its care. The core is stranded from all metal composite wires of high purity aluminium reinforced with alumina fibres. The outer current carrying wires are a hardened aluminium zirconium alloy. Compared to the same dia steel core conductor ACCR has the same strength, less weight and less sag at high loads.
