A lattice electrical pylon, also known as a lattice tower or lattice transmission tower, is a tall, man-made structure that is designed to support high-voltage power lines. The tower is made up of a lattice of metal beams or girders that are bolted together to form a sturdy framework. The lattice design provides strength and stability to the tower while using a minimum amount of material, making it a cost-effective solution for supporting high-voltage transmission lines.
