Overhead Line Crossing

An overhead line crossing is the crossing of an obstacle—such as a traffic route, a river, a valley or a strait—by an overhead power line. The style of crossing depends on the local conditions and regulations at the time the power line is constructed. Overhead line crossings can sometimes require extensive construction and can also have operational issues. In such cases, those in charge of construction should consider whether a crossing of the obstacle would be better accomplished by an underground or submarine cable.

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

    Twenty men crossing a bridge,
    Into a village,
    Are twenty men crossing twenty bridges,
    Into twenty villages,
    Or one man
    Crossing a single bridge into a village.
    Wallace Stevens (1879–1955)

    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)

    The line it is drawn
    The curse it is cast
    The slow one now
    Will later be fast
    As the present now
    Will later be past
    The order is
    Rapidly fadin’.
    And the first one now
    Will later be last
    For the times they are a-changin’.
    Bob Dylan [Robert Allen Zimmerman] (b. 1941)
