In electrical systems, which material is generally known for greater flexibility over long distances?

Aluminum wire is recognized for its greater flexibility, especially over long distances. This characteristic makes aluminum a preferred choice for utility applications where long spans of wiring are essential, such as in overhead power lines.

Aluminum's lower density compared to copper contributes to its flexibility. While copper is an excellent conductor and has superior electrical conductivity, aluminum's strength-to-weight ratio allows it to carry the same amount of current while being easier to manage and install over longer distances. This means that, in applications where long runs of wiring are necessary, aluminum can be more practical due to its lighter weight and flexible nature.

Understanding these properties is crucial for utility arborists, as they must often consider the most efficient and manageable materials for installations and repairs in electrical systems. Copper is typically favored for short runs or connections where minimal resistance is needed, but for extensive networking or transmission lines, aluminum's advantages become more pronounced.
