Note: Current ratings based on IS 694:2010 for 3-core cables at ambient temperature 30°C with 30°C rise. Aluminum cables have ~15-20% lower current capacity than copper but are lighter and more cost-effective for large installations.

3. ALUMINUM VS COPPER - ADVANTAGES

Aluminum Advantages

  • 60-70% lower cost per meter
  • 3x lighter weight (easier installation)
  • Excellent for large-scale distribution networks
  • Lower material cost for bulk installations
  • Ideal for infrastructure & utility projects

Trade-offs

4. Applications

  • 15-20% lower current carrying capacity
  • Slightly higher resistance per unit length
  • Requires larger cross-section for same amperage
