However, they have significant disadvantages. Overhead lines are vulnerable to lightning strikes which can cause interruption. Overhead lines use bare conductors and can cause damage if they break. They are considered to be unsightly as they mar the scenery of the landscape. The maintenance cost of overhead lines is more and the voltage drop in overhead lines is more.
