Aluminum cables are generally selected for use in

• A. Low voltage distribution
• B. Data cables
• C. Residential wiring
• D. High voltage applications

Answer: (D)

Aluminum is chosen for high-voltage lines because its light weight and lower cost enable long spans and large cross-sections without making the supporting structures prohibitively expensive. In transmission and distribution, keeping the conductor light reduces tower and insulator requirements, and aluminum can carry the necessary current when sized appropriately. It’s common to use aluminum with steel reinforcement (ACSR) to provide both conductivity and tensile strength for long, overhead runs. For data cables and residential wiring, copper is typically preferred due to its higher electrical conductivity, easier termination, and better performance in smaller, more flexible cables. So the material choice aligns with the needs of long-distance, high-voltage transmission versus shorter, lower-voltage or data-focused applications.
