Editing Overhead power line (section)

==Compact transmission lines==
{{more citations needed section|date=March 2012}}
A compact overhead transmission line requires a smaller right of way than a standard overhead powerline. Conductors must not get too close to each other. This can be achieved either by short span lengths and insulating crossbars, or by separating the conductors in the span with insulators. The first type is easier to build as it does not require insulators in the span, which may be difficult to install and to maintain.

Examples of compact lines are:
* Lutsk compact overhead powerline {{coord|50.774673|N|25.385215|E|type:landmark|name=Startpoint of Lutsk Compact Overhead Powerline}}
* Hilpertsau-Weisenbach compact overhead line {{coord|48.737898|N|8.355660|E|type:landmark|name=Startpoint of Hilpertsau-Weisenbach Powerline}}

Compact transmission lines may be designed for voltage upgrade of existing lines to increase the power that can be transmitted on an existing right of way.<ref>Beaty, H. Wayne; Fink, Donald G., ''Standard Handbook for Electrical Engineers (15th Edition)''
