2025-08-12

Answer: The choice between overhead and underground power lines depends on a variety of factors, including cost, reliability, and aesthetics.

Overhead Power Lines

  • Advantages: They are significantly less expensive to install and repair, as they are easily accessible. They also dissipate heat more efficiently.

  • Disadvantages: They are more susceptible to damage from severe weather, trees, or wildlife, which can lead to frequent power outages.

underground Power Lines

  • Advantages: They are more resilient to weather-related damage and offer a more aesthetically pleasing solution by being hidden from view.

  • Disadvantages: They are much more expensive to install, and locating and repairing a fault can be a time-consuming and costly process.
