Aluminum cables are electrical conductors made with aluminum instead of copper. Theyre widely used in power transmission and distribution systems due to their cost-effectiveness and lighter weight.
| Feature | Aluminum Cables |
|---|---|
| Conductor Material | Aluminum (or aluminum alloy) |
| Weight | ~30–50% lighter than copper |
| Cost | Significantly cheaper than copper |
| Conductivity | About 61% of coppers conductivity |
| Corrosion | Prone to oxidation, needs proper lugs and anti-oxidant paste |
| Flexibility | Less flexible and more brittle than copper |
| Expansion | Higher thermal expansion than copper, can loosen connections |
