High-Voltage Power Line

High-Voltage Power Line


an electric transmission line with a voltage exceeding 1 kilovolt. High-voltage lines may be overhead or underground (also underwater).

Overhead high-voltage power lines are installations for transmitting and distributing electric power through wires that are located outdoors and are attached to poles by means of insulators and fixtures. The poles, which are made of wood, reinforced concrete, or metal, are spaced at distances of 50-500 m from each other, depending upon the kind of conductor and the type of pole. The distance of the conductor from the ground is at least 6-8 m.

Underground (or underwater) high-voltage power lines, which use wires inside special insulation, are utilized to distribute electric power in municipal and industrial areas, as well as when crossing extensive water obstacles.
