Aluminum alloy cables (e.g., AA-8000 series per ASTM B800) are widely used in power distribution due to their lightweight, cost-effectiveness, and corrosion resistance. Key applications include:
1. Power Transmission & Distribution
Building Wiring: Replace copper in residential/commercial circuits (NEC & IEC compliant).
Utility Grids: Overhead lines and underground feeders (AA-1350/AA-8030 alloys).
Renewable Energy: Solar/Wind farm collection systems (flexible, oxidation-resistant).
2. Industrial & Infrastructure
Substations: Busbars and transformer connections.
Transportation: Metro/railway traction power (lightweight reduces load).
Temporary Power: Construction sites (easy handling).
Cost Savings: ~40% lighter & cheaper than copper (similar ampacity with larger sizes).
Durability: Superior creep/thermal performance vs. pure aluminum.
Compliance: Meets ASTM B800/IEC 62004 for mechanical/electrical properties.
Common Types: AA-8030 (IEC), AA-8176 (UL), AA-1350 (overhead lines).
