An anchor portal is a support structure for overhead electrical power transmission lines in the form of a portal for the installation of the lines in a switchyard. Anchor portals are almost always steel-tube or steel-framework constructions. ...more on Wikipedia about "Anchor portal"
Anchor pylons or strainer pylons utilize horizontal insulators and occur at the endpoints of conductors. Such endpoints are necessary when interfacing with other modes of power transmission (see image) and, due to the inflexibility of the conductors, when significantly altering the direction of the pylon chain. Anchor pylons are also employed at branch points as branch pylons and must occur at a maximum interval of 5 km, due to technical limitations on conductor length. Conductors are connected at such pylons by a short conductor cable "strained" between both ends. They often require anchor cables to compensate for the asymmetric attachment of the conductors. Therefore, anchor pylons tend to be more stably built than a support pylon and are often used, particularly in older construction, when the power line must cross a large gap, such as a railway line, river, or valley. ...more on Wikipedia about "Anchor pylon"
In the layout of an overhead electrical transmission system, a branch pylon denotes a pylon which is used to start a line branch. The branch pylon is responsible for holding up both the main-line and the start of the branch line, and must be structured so as to resist forces from both lines. ...more on Wikipedia about "Branch pylon"
A concrete pylon is an electricity pylon made from reinforced concrete. Concrete pylons are manufactured as a rule in the concrete work and put up at the place of assembly. Concrete pylons are used in Germany normally only for lines with operating voltages below 30kV. In exceptional cases concrete pylons are used also for 110kV-lines, as well as for the public grid or for the railway traction current grid. In Switzerland, concrete pylons with heights of up to 75 metres are used for 380kV-overhead lines. Also called a concrete pole. ...more on Wikipedia about "Concrete pylon"
A crossing pylon is an electricity pylon for the realization of an overhead line crossing of a river, a strait or a valley. ...more on Wikipedia about "Crossing pylon"
A pylon is a tall steel lattice structure used to support overhead electricity conductors for power transmission. In American English, these are known as transmission towers or masts. ...more on Wikipedia about "Electricity pylon"
A lattice steel pylon is an electricity pylon consisting of a steel framework construction. Lattice steel pylons can be used for powerlines of all voltages, however their use for lines with operating voltages under 50kV is quite rare. For lines with operating voltages over 50kV, lattice steel pylons are the form of pylon used most often. ...more on Wikipedia about "Lattice steel pylon" Things Go Better with www.shortopedia.com.
A long distance anchor pylon is an anchor pylon at the end of a line section with a long span. Large gaps between pylons reduces the restraints on the movement of the attached conductors. In such situations, conductors may be able to swing into contact with each during high wind, potentially creating a short circuit. Long distance anchor pylons must be very stably built due to the large weight of the exceptionally long cables. They are implemented occasionally as portal pylons. In extreme cases long distance anchor pylons are constructed in pairs, each supporting only a single cable, in an effort to reduce the strain of large spans. ...more on Wikipedia about "Long distance anchor pylon"
Pylon is the Greek term for a monumental gate or door built in front of an Egyptian temple. It consists of two towers and the entrance between them, which is generally about half the height of the towers. Contemporary paintings of pylons show them with long poles flying banners. ...more on Wikipedia about "Pylon (architecture)"
A pylon transformer is a transformer mounted on a pylon. Because of weight restrictions transformers for pylon transformers are only built for voltages under 30kV. ...more on Wikipedia about "Pylon transformer"
The Pylons of Duisburg-Rheinhausen are the two electricity pylons of the combined 220 kV/110 kV powerline for 4 circuits (2 for 220 kV, 2 for 110 kV) crossing the River Rhine at Duisburg- Rheinhausen with a span width of 570 metres. These 118.8 metre high pylons were built in 1926 and are equipped with 6 crossbars in 6 levels for carrying the 12 conductors. ...more on Wikipedia about "Pylons of Duisburg-Rheinhausen"
The Pylons of the Ghesm Crossing are two 130 metre high pylons, carrying a 230kV- powerline over the Strait of Ghesm in Iran. One of these pylons was founded on a caisson in the strait. Both pylons have two crossbars with span widths of 36.20 metres and 13.8 metres for 6 conductors. The line span between the two pylons is 1585 metres. Unlike other 230kV-powerlines, no ground conductors are used. ...more on Wikipedia about "Pylons of Ghesm Crossing"
The pylons of the Pearl River Crossing are three electricity pylons with heights of 240 metres, 253 metres, and 80 metres. They carry the 500kV-three phase AC powerline between Jiangmen and Sha Jiao in Guangdong, China at the crossing of the Pearl River. The 253 metre high pylon was built on an artificial island in the Pearl River and is the highest pylon in the world. The 240 metre high pylon is situated at the east side of Pearl River, while the 80 metre high pylon stands on the west side of the river. The span width of the line between the 253 metre and the 240 metre high pylon is 1547 metres. At this span the line is at its deepest point in a height of 70 metres over the Pearl River. The span width of the two crossbars of the 240 and the 253 metre high pylons are 63.5 metres and 54.5 metres. The pylons at the Pearl River Crossing were built in 1987. ...more on Wikipedia about "Pylons of Pearl River Crossing"
A roof stand is a small electricity pylon on a building roof. Via a cable inside roof stands the current supply of the house takes place in populated areas with overhead line supply, on which the roof stand stands. ...more on Wikipedia about "Roof stand" I wish I had a shortopedia.
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 always used for overhead lines for high voltage direct current transmissions and traction current lines. For three-phase current it is used, if the height of pylons may not exceed a certain value. ...more on Wikipedia about "Single-level pylon"
A steel tube pylon is a pylon, which is manufactured from a steel tube. A steel tube pylon is installed as a rule completely in the manufacture work and set up then at the place of assembly with a crane. In Germany steel tube pylons are also established predominantly for medium voltage lines, in addition, for high voltage transmission lines or two electric circuits for operating voltages by up to 110 kV. In France steel tube pylons are used frequently also for pylons by 380 kV lines in the USA also for 500 kV lines. ...more on Wikipedia about "Steel tube pylon"
A wood pylon is an electricity pylon made of wood. For support pylons a straight trunk impregnated with tar is usually used, which carries one or more cross beams with the conductor cables on the top. For anchor pylons constructions looking like a v or an a are used, because these can stand higher forces. ...more on Wikipedia about "Wood pylon"
