Three-level pylon
From Wikipedia, the free encyclopedia
A three-level pylon is a pylon designed to arrange conductor cables on three crossbars in three levels. For two three-phase circuits (6 conductor cables), it is usual to use fir tree pylons and barrel pylons. Three-level pylons are taller than other pylon types, but require only a small right-of-way. They are very popular in a number of countries such as Belgium.
A barrel pylon is a common type of three-level pylon. It arranges two three-phase circuits in three levels, at which the lowest cross beam possesses a smaller span than the middle crossbar and thus a larger span than the highest crossbar. As a rule the highest and the lowest cross beam have the same span at ton masts.
