Q: Why is aluminum preferred for electrical wiring and grids?
A: Aluminum's high conductivity (60% of copper's) and lower cost make it ideal for power transmission lines. Its lightweight nature reduces tower strain, enabling longer spans between pylons. Aluminum alloys resist corrosion from weather, ensuring grid durability. In homes, aluminum wiring is safer than older copper systems due to oxidation resistance. Electric vehicles (EVs) rely on aluminum cables to reduce weight and enhance battery efficiency. Innovations like aluminum-air batteries are being explored for renewable energy storage. Utility companies increasingly adopt aluminum to upgrade aging infrastructure sustainably. However, proper installation is crucial to prevent overheating. Overall, aluminum balances performance, cost, and sustainability in electrical applications.
