Long-distance anchor pylon
From Wikipedia, the free encyclopedia
A long distance anchor pylon is an anchor pylon at the end of a line section with a long span. Large gaps between pylons reduces the restraints on the movement of the attached conductors. In such situations, conductors may be able to swing into contact with each during high wind, potentially creating a short circuit. Long distance anchor pylons must be very stably built due to the large weight of the exceptionally long cables. They are implemented occasionally as portal pylons. In extreme cases long distance anchor pylons are constructed in pairs, each supporting only a single cable, in an effort to reduce the strain of large spans.
