Branch pylon

Branch pylon

In the layout of an overhead electrical transmission system, a branch pylon is a pylon that is used to start a line branch. The branch pylon is responsible for holding up both the main-line and the start of the branch line, and must be structured so as to resist forces from both lines.

Branch pylons frequently, but not always, have one or more cross beams transverse to the direction of travel of the line for the admission of the branching electric circuits. There are also branch pylons where the cross beams of the branching electric circuits lie in the direction of travel of the main line. Branch pylons without additional cross beams are occasionally constructed. Branch pylons are nearly always anchor pylons (as they normally must ground the forces from the branch line). Branch pylons are often constructed similarly to final pylons; however, at a branch pylon the overhead line resumes in both directions, as opposed to only one direction as with a final pylon.
