What materials are most commonly used in overhead power construction?

The most commonly used materials in overhead power construction are aluminum and copper conductors. These materials are favored for several reasons.

Aluminum is lightweight, which makes it easier to handle and install over long distances. It also provides a good balance between conductivity and cost, making it a popular choice for utility companies. Aluminum conductors can carry substantial electrical loads while also being resistant to corrosion, which is vital for outdoor installations exposed to the elements.

Copper, on the other hand, has higher electrical conductivity than aluminum, which allows for more efficient power transmission over shorter distances. Its durability and resistance to oxidation make it suitable for connections and components in the powered network. Moreover, while copper is more expensive than aluminum, its effectiveness in improving electrical efficiency justifies its use in certain critical applications.

Overall, the combination of aluminum and copper provides a practical and efficient solution for overhead power lines, facilitating the reliable transmission of electricity from generation points to consumers.
