Why Are Aluminum Wires Used in Power Transmission Towers Instead of Copper Wires

Many people wonder why aluminum wires are used in power transmission towers instead of copper wires, even though copper is more efficient in conducting electricity. In this article, we will explain the reasons behind using aluminum wires instead of copper wires. The main reasons are as follows:

1. Aluminum is Lighter than Copper:

Aluminum wires are much lighter than copper wires, which reduces the overall weight of the cables and minimizes wire sag over medium and long distances.

2. High Cost of Copper:

Aluminum wires are cheaper and more readily available compared to copper wires. Since electrical power is transmitted over extremely long distances—from power plants to cities and factories—the cost of using copper cables would be significantly higher.

3. Aluminum is More Flexible:

Aluminum wires are more flexible than copper wires, making them easier to shape and connect without complications.

Conclusion:

This answers the question of why aluminum wires are preferred over copper wires in high-voltage power transmission towers. Don't forget to share this article with your friends so that everyone can benefit. Stay safe, and see you in the next topic.
