Power lines are essential components of the electrical grid, designed to transport electricity from power plants to homes and businesses. They come in various forms, including overhead and underground lines, and are crucial for ensuring a reliable power supply. High-voltage power lines, in particular, are used to transmit electricity over long distances with minimal energy loss. These lines are supported by tall towers or poles and are often seen stretching across landscapes. Safety measures are vital around power lines, as they carry high voltage electricity that can be dangerous. Understanding their role helps us appreciate the infrastructure that powers our daily lives.
