What is a "pylon"?

A pylon is a tall, upright structure designed to support and hold electrical wires or cables above the ground. Made from materials such as steel or concrete, pylons are spaced at regular intervals to carry electricity over long distances. They are essential for connecting power stations to homes and businesses, helping to distribute electricity safely. Pylons can be found in both rural and urban areas, often standing out in the landscape due to their size and height. They are built to withstand weather conditions and to ensure that electrical lines remain stable and secure.
