Traction current line — A traction current line is a high voltage transmission line for the supply of railways with traction current for powering locomotives. A network of traction current lines is needed in countries where trains use single phase alternating current of … Wikipedia
Traction power network — articleissues original research=August 2008 POV=August 2008 refimprove=May 2007A traction power network is an electricity grid for the supply of electrified railroads. The installation of separate traction power network generally is only done if… … Wikipedia
Electricity pylon — An electricity pylon or transmission tower is a tall, usually steel lattice structure used to support overhead electricity conductors for electric power transmission.High voltage AC transmission towersThree phase electric power systems are used… … Wikipedia
Hybrid pylon — A hybrid pylon is a pylon which carries electric circuits for different types of current. In principle, hybrid pylons supply parallel guidance to the following types of electrical lines:* Three phase alternating current and traction current *… … Wikipedia
Single-level pylon — A single level pylon is an electricity pylon for an arrangement of all conductor cables on a pylon in one level. The single level pylon leads to a low height of the pylons, connected with the requirement for a large right of way. It is nearly… … Wikipedia
Concrete pylon — A concrete pylon, or concrete pole, is an electricity pylon made from reinforced concrete. Concrete pylons are manufactured at the factory and put up at the power line s right of way.Because of its durability and ease of manufacturing and… … Wikipedia
High-voltage direct current — HVDC or high voltage, direct current electric power transmission systems contrast with the more common alternating current systems as a means for the bulk transmission of electrical power. The modern form of HVDC transmission uses technology… … Wikipedia
Overhead lines — This article is about the transmission of electrical power to road and rail vehicles. For transmission of bulk electrical power to general consumers, see Electric power transmission. For powerlines mounted on pylons, see overhead power line.… … Wikipedia
Transmission tower — A delta pylon carrying a 400kV power line towards Madrid. A transmission tower (colloquially termed an electricity pylon in the United Kingdom and parts of Europe, an ironman in Australia, and a hydro tower in parts of Canada) is a tall structure … Wikipedia
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… … Wikipedia
