An overhead power line is a structure used in electric power transmission and distribution to transmit electrical energy along large distances. It consists of one or more conductors (commonly multiples of three) suspended by towers or poles. Since the surrounding air provides good cooling, insulation along long passages, and allows optical inspection, overhead power lines are generally the lowest-cost method of power transmission for large quantities of electric energy.

A feeder, or main power line, carries electricity from the substation to an FPL local/regional service area. These power lines are usually along major roads and thoroughfares.
The article provides an overview of transmission lines—overhead, underground, and subtransmission—and explains how they are used to transport electrical energy across distances.
The relationship between the atmosphere and the power level at the receiver terminal is complex due to the daily change in climate state, which randomly occurs.
Solar-powered base stations do not need power lines to the areas that do not have existing power, hence no cost will be incurred in buying and running a generator to the base station.
