What material is usually used for line conductors that experience Aeolian vibration?

Line conductors that experience Aeolian vibration are commonly made from aluminum. This is due to several key characteristics of aluminum that make it suitable for this specific application.

Firstly, aluminum is lightweight compared to other conductive materials, which allows for longer spans between pylons without excessive weight that could lead to structural issues. This lightweight quality is particularly beneficial in areas prone to vibration, as it reduces the overall load on the supporting structures.

Secondly, aluminum possesses excellent conductivity, which is important for effective electrical transmission. Although copper has a slightly higher conductivity, aluminum's conductivity-to-weight ratio is favorable for overhead lines, making it a preferred choice.

Additionally, aluminum has good resistance to corrosion, which can be particularly important given that these conductors are often exposed to various environmental conditions. The durability and resilience of aluminum in outdoor settings contribute to its widespread use in line conductors subject to Aeolian vibration.

Other materials listed, such as gold and carbon fiber, are not practical for line conductors due to high costs (gold) or inadequate electrical conductivity (carbon fiber), which limit their use in large-scale applications like power lines. Thus, aluminum's combination of lightweight, effective conductivity, and corrosion resistance makes it the ideal choice for line conductors that experience Aeolian vibration
