How AAC Cable Compares to Other Overhead Conductors
| Type of Conductor | Material | Best Used For | Weight Comparison | Corrosion Resistance |
|---|---|---|---|---|
| AAC | Pure Aluminum | Short spans, urban areas | Light | Excellent |
| ACSR | Aluminum + Steel Core | Long spans, high tension lines | Medium | Good |
| AAAC | Aluminum Alloy | Long spans, corrosion-prone areas | Light | Excellent |
AAC is generally best when the priority is cost, ease of installation, and corrosion protection in short span applications.
