ACSR steel-reinforced aluminum conductor. High tensile strength for long spans. Galvanized steel core resists corrosion.
Application
ASTM B232 aluminum conductor steel reinforced (ACSR) for long-span overhead transmission lines, river crossing projects, extra-high voltage (EHV) transmission, heavy-load feeder circuits, and long-distance bulk power transmission. Galvanized steel core with 1350-H19 aluminum stranded layers. Available in multi-layer construction.
Core Strengths
Long-span overhead lines need high tensile strength and sag control. Our ACSR combines steel core strength with aluminum conductivity. Galvanized core resists corrosion. High mechanical reliability for EHV transmission and river crossings. ASTM B232. Customizable stranding.
Standard
IEC61089 , ASTM B-232, BS215
Construction
☉〉 Outer strands: High-purity aluminum
☉〉 Core/center strand: Steel (galvanized or aluminized) for strength
☉〉 Stranding: Concentric layers of aluminum around steel core
Features
☉〉 High mechanical strength (steel core supports long spans)
☉〉 Good conductivity (aluminum provides efficient current transmission)
☉〉 Lightweight relative to copper conductors
☉〉 Suitable for long-span overhead transmission and river crossings
☉〉 Cost-effective for high-voltage lines
