Aluminum Conductors Steel Reinforced (ACSR)

Aluminum Conductor Steel Reinforced (ACSR) is a concentric-lay-stranded bare overhead conductor combining high-purity 1350-H19 aluminum strands for superior conductivity with a high-tensile galvanized (or specialty-coated) steel core for exceptional mechanical strength. Designed for long-span transmission and distribution lines from 11 kV to 1000 kV+, ACSR delivers the optimal balance of ampacity, low sag, and cost-efficiency under heavy ice, wind, and thermal loads.
