overhead lines are directly exposed to the elements. They are vulnerable to damage from high winds, ice storms, lightning strikes, and falling trees. While repairs are typically faster and easier to locate, the frequency of weather-related faults is a major disadvantage.

underground cables, by contrast, are largely unaffected by these conditions. This makes them a much more reliable option in areas prone to severe weather. However, they can be susceptible to damage from flooding, seismic activity, or soil disturbances.
