Power lines are tall structures that carry electricity from power plants to homes and businesses. They are made of strong materials like steel or aluminum and are often suspended high above the ground on wooden or metal poles. These lines help distribute electrical energy over long distances, ensuring that people have access to electricity for lighting, heating, and appliances. There are different types of power lines, including high-voltage transmission lines and distribution lines. High-voltage lines transport electricity over long distances, while distribution lines deliver it to local areas. Safety measures are important around power lines, as they can carry dangerous levels of electricity.
