The choice between overhead and underground power lines depends on various factors, including cost, environment, and technical requirements.

• overhead lines:

  • Pros: Generally less expensive to install and easier to maintain and repair.

  • Cons: More susceptible to damage from severe weather, wildlife, and vegetation. They can also have a greater visual impact on the landscape.

• underground Lines:

  • Pros: Less vulnerable to weather and environmental damage, and they have a minimal visual impact.

  • Cons: Significantly more expensive to install, and repairs can be complex and time-consuming. They also have operational limitations, such as higher energy losses over very long distances.
