Supporting tower:
Wind pressure has a more predominant effect on supporting towers compared to other components of a transmission line system. Supporting towers are tall structures that bear the weight of the transmission lines and are exposed to the full force of wind. The wind exerts pressure on the tower, causing it to sway or vibrate. This can lead to structural fatigue and, in extreme cases, tower failure. Proper design and reinforcement of supporting towers are essential to ensure the stability and longevity of the transmission line system.

Neutral wires, Transmission lines, and Insulators:
While wind pressure can also impact neutral wires, transmission lines, and insulators, their design and placement are typically less affected by wind compared to supporting towers. Neutral wires are usually smaller in diameter and are designed to carry minimal current, so the impact of wind pressure on them is relatively minor. Transmission lines are often designed with sufficient clearance from the ground and other structures to minimize the effects of wind. Insulators are also designed to withstand mechanical stresses, including those caused by wind, but they are less susceptible to wind pressure compared to supporting towers.

In conclusion, supporting towers are the components of a transmission line system that are most affected by wind pressure. Proper design, maintenance, and reinforcement of supporting towers are crucial to ensure the reliability and safety of the transmission line system.
