Overhead Line Crossing - Overhead Line Crossing of Valleys

Overhead Line Crossing of Valleys

Overhead line crossings of valleys consist of two anchor pylons, one at either end of the valley. If the topography of the valley is suitable, these do not need to be very high. In very wide valleys, it is better to use a pylon for each phase in order to achieve sufficient distance between the conductors. In these cases there is frequently a further anchor pylon behind the crossing, used in order to realize the angle change of the conductor cables behind these. The problems associated with large spans also exist in these cases, but these can be easily and economically ameliorated, if the topography does not require high crossing pylons, by using a separate pylon for each conductor.

Famous quotes containing the words overhead, line, crossing and/or valleys:

    During a walk or in a book or in the middle of an embrace, suddenly I awake to a stark amazement at everything. The bare fact of existence paralyzes me... To be alive is so incredible that all I can do is to lie still and merely breathe—like an infant on its back in a cot. It is impossible to be interested in anything in particular while overhead the sun shines or underneath my feet grows a single blade of grass.
    W.N.P. Barbellion (1889–1919)

    What is line? It is life. A line must live at each point along its course in such a way that the artist’s presence makes itself felt above that of the model.... With the writer, line takes precedence over form and content. It runs through the words he assembles. It strikes a continuous note unperceived by ear or eye. It is, in a way, the soul’s style, and if the line ceases to have a life of its own, if it only describes an arabesque, the soul is missing and the writing dies.
    Jean Cocteau (1889–1963)

    This was charming, no doubt: but they shortly found out
    That the Captain they trusted so well
    Had only one notion for crossing the ocean,
    And that was to tingle his bell.
    Lewis Carroll [Charles Lutwidge Dodgson] (1832–1898)

    I do like a little romance ... just a sniff, as I call it, of the rocks and valleys.... Of course, bread-and-cheese is the real thing. The rocks and valleys are no good at all, if you haven’t got that.
    Anthony Trollope (1815–1882)
