A wood pylon is a pylon made of wood. For support pylons a straight trunk impregnated with tar is usually used, which carries one or more cross beams with the conductor cables on the top. For anchor pylons constructions looking like a v or an a are uses, because these can stand higher forces. Because of the limited height of available trees the maximum height of wood pylons is limited (approx. 30 meters). In Germany wood pylons are used as a rule only for lines with voltages to approximately 30 kV, in the USA are used wood pylons themselves for lines with voltages up to 345 kV.
