Overhead lines are power lines that are supported by poles or towers above the ground. They are typically used for high-voltage transmission and distribution lines. Overhead lines are less expensive to build and maintain than underground lines, and they are also easier to inspect and repair. However, they are more sensitive to damage from weather events, wildlife, and human activity. Underground lines are power lines that are buried in the ground. They are typically used for low-voltage distribution lines and in areas where overhead lines are not possible, such as in urban areas or environmentally sensitive areas. Underground lines are less sensitive to damage from weather events and human activity, but they are more expensive to build and maintain than overhead lines.
Well, Which is best?
The best type of power line for a particular application depends on a number of factors, including cost, reliability, and environmental impact. In general, overhead lines are the best option for high-voltage transmission and distribution lines, while underground lines are the best option for low-voltage distribution lines and in areas where overhead lines are not possible.
