Why overhead transmission line conductors are stranded?


Overhead transmission line conductors are stranded for several reasons.

Stranding increases flexibility, making the conductor more resistant to mechanical stress and vibrations caused by wind or other external factors.

This flexibility also allows for easier installation over uneven terrain.

Furthermore, stranded conductors reduce the skin effect and proximity effect, phenomena that can occur at high frequencies, improving the overall efficiency of power transmission.

Additionally, the stranding process enhances the conductor’s strength and durability, contributing to its longevity and ability to withstand environmental conditions.
