AAAC 6201-T81 aluminum-magnesium alloy conductor. Superior strength-to-weight ratio, excellent sag characteristics. Corrosion resistant.
Application
ASTM B399 all-aluminum alloy conductor (AAAC) for overhead transmission and distribution lines near ocean coastlines, across basins/rivers/valleys, and in corrosive environments where steel in ACSR poses corrosion issues. 6201-T81 high-strength aluminum-magnesium alloy, concentric-lay-stranded.
Core Strengths
Coastal transmission lines require conductors resistant to salt corrosion. Our AAAC uses 6201-T81 aluminum-magnesium alloy to eliminate ACSR's steel core corrosion. Superior strength-to-weight ratio, excellent sag characteristics. Lower power losses than single-layer ACSR.
Standard
IEC61089,ASTM B-399,BS3242,NFC34125
Construction
☉〉 AA-6101 aluminium alloy,Concentrically stranded
☉〉 Max. Size 2500MCM, Max. str. No. 91Wires
Features
☉〉 High conductivity (≈52.5% IACS)
☉〉 Excellent mechanical strength (higher than AAC, similar to ACSR)
☉〉 Superior corrosion resistance (better than ACSR, no galvanic issues)
☉〉 Lightweight with high strength-to-weight ratio
☉〉 Suitable for long-span overhead transmission and distribution
