Which of the following factors can increase the risk of vibration-related issues in line conductors?

Long spans in line conductors can significantly increase the risk of vibration-related issues due to the potential for greater oscillation and movement under wind and other environmental forces. When spans are long, the conductor has more freedom to sway, which can lead to increased fatigue and wear at suspension points. This oscillation can amplify stresses on the conductor itself and any supporting structures, leading to potential failures or damage over time.

In contrast, shorter spans tend to limit this type of movement, reducing the risk of vibration-related issues. Regular maintenance plays a critical role in managing the integrity of the conductors and their components, helping to prevent problems before they arise. The use of thicker conductors can also enhance stability and resilience against vibrations; their weight and structural integrity often contribute to less movement during environmental stressors.
