Overhead power lines are electrical cables that are suspended above the ground, typically on tall poles or towers. They are used to transmit electricity from power plants to homes and businesses. These lines are often seen along roads and in rural areas, providing a vital connection to the electrical grid. The cables are usually made of aluminum or copper and are insulated to prevent electrical hazards. Overhead power lines can be affected by weather conditions, such as strong winds or ice, which may cause outages. Safety measures are important, as utility workers must maintain these lines to ensure reliable electricity delivery.
