What is the main advantage of underground distribution systems compared to overhead systems?

The main advantage of underground distribution systems is reduced exposure to weather-related interruptions and improved visibility. Underground systems are less susceptible to the adverse effects of weather events, such as high winds, ice, or fallen trees, which can cause power outages in overhead lines. By being buried below ground, these systems avoid many of the hazards that lead to service disruptions, resulting in more reliable service for consumers.

Additionally, underground systems do not contribute to visual clutter in the environment since power lines and equipment are hidden from view, improving the aesthetic appeal of neighborhoods and urban areas. The reduction in visual impacts is particularly significant in areas where scenic views or property values might be affected by the presence of power poles and overhead lines. Therefore, underground distribution not only mitigates service reliability issues associated with bad weather but also enhances the overall appearance of the area where it is implemented.
