    Steel and Transmission of Electric Power IspatGuru

    A lattice tower is a framework construction made of steel sections. Lattice towers are used for power lines of all voltages, and are the most common type for high-voltage transmission lines. Lattice towers are usually made of galvanized steel. A lattice tower is usually assembled at the location where it is to be erected. This makes very tall TRANSMISSION 101:THE BASICS Transmission Structures are generally steel lattice towers, wooden H-Frames or single-pole steel. (photos below of each). Lower voltage transmission systems:161-kV and 115-kV systems are responsible for transmitting power from the larger transmission system and
