A transmission tower (also electricity pylon , hydro tower , or pylon ) is a tall structure , usually a lattice tower made of steel that is used to support an overhead power line . In electrical grids , transmission towers carry high-voltage transmission lines that transport bulk electric power from generating stations to electrical substations , from which electricity is delivered to end consumers; moreover, utility poles are used to support lower-voltage sub-transmission and distribution lines that transport electricity from substations to electricity customers.
102-693: Queen Elizabeth Olympic Park is a sporting complex and public park in Stratford , Hackney Wick , Leyton and Bow , in east London . It was purpose-built for the 2012 Summer Olympics and Paralympics , situated adjacent to the Stratford City development. It contains the Olympic stadium , now known as the London Stadium, and the Olympic swimming pool together with the athletes' Olympic Village and several other Olympic sporting venues and

Two well-known wide river crossings are the Elbe Crossing 1 and Elbe Crossing 2 . The latter has the tallest overhead line masts in Europe, at 227 m (745 ft) tall. In Spain, the overhead line crossing pylons in the Spanish bay of Cádiz have
510-443: A line is constructed using towers designed to carry several circuits, it is not necessary to install all the circuits at the time of construction. Indeed, for economic reasons, some transmission lines are designed for three (or four) circuits, but only two (or three) circuits are initially installed. Some high voltage circuits are often erected on the same tower as 110 kV lines. Paralleling circuits of 380 kV, 220 kV and 110 kV-lines on

Steel tube or concrete poles are also often used for these lines. However, railway traction current systems are two-pole AC systems, so traction lines are designed for two conductors (or multiples of two, usually four, eight, or twelve). These are usually arranged on one level, whereby each circuit occupies one half of

Instead, they are used to build multi-pole structures, such as H-frame and K-frame structures. The voltages they carry are also limited, such as in other regions, where wood structures only carry voltages up to approximately 30 kV. In countries such as Canada or the United States, wooden towers carry voltages up to 345 kV; these can be less costly than steel structures and take advantage of

2550-1051: Is the name for the structure used in the industry in the United States and some other English-speaking countries. In Europe and the U.K., the terms electricity pylon and pylon derive from the basic shape of the structure, an obelisk with a tapered top. In Canada, the term hydrotower is used, because hydroelectricity is the principal source of electricity for the country. Three-phase electric power systems are used for high voltage (66- or 69-kV and above) and extra-high voltage (110- or 115-kV and above; most often 138- or 230-kV and above in contemporary systems) AC transmission lines. In some European countries, e.g. Germany, Spain or Czech Republic, smaller lattice towers are used for medium voltage (above 10 kV) transmission lines too. The towers must be designed to carry three (or multiples of three) conductors. The towers are usually steel lattices or trusses (wooden structures are used in Australia, Canada, Germany, and Scandinavia in some cases) and
2652-461: The Elbe crossing 1 and Elbe crossing 2 ). Assembly of lattice steel towers can be done using a crane . Lattice steel towers are generally made of angle-profiled steel beams (L-beam or T-beams ). For very tall towers, trusses are often used. Wood is a material which is limited in use in high-voltage transmission. Because of the limited height of available trees, the maximum height of wooden pylons
2754-455: The Hamburg water and navigation office. For crossing broad valleys, a large distance between the conductors must be maintained to avoid short-circuits caused by conductor cables colliding during storms. To achieve this, sometimes a separate mast or tower is used for each conductor. For crossing wide rivers and straits with flat coastlines, very tall towers must be built due to the necessity of

Up to 110 kV they often were made from wood, but higher voltage lines use steel pylons. Smaller single circuit pylons may have two small cross arms on one side and one on
7344-721: The northwest boundary of the modern London Borough of Newham . In this way the River Lea and the complex network of the Bow Back Rivers mark the western limits of the area, which also extends north as far as the boundary of the London Borough of Waltham Forest . Most of Stratford is in the E15 postal area, however the Royal Mail has given the new E20 postcode to the Olympic Park and Stratford City developments; this
7446-494: The other. One level pylons only have one cross arm carrying 3 cables on each side. Sometimes they have an additional cross arm for the protection cables. They are frequently used close to airports due to their reduced height. Danube pylons or Donaumasten got their name from a line built in 1927 next to the Danube river . They are the most common design in central European countries like Germany or Poland. They have two cross arms,
7548-468: The park and Stratford City the postcode E20 , which had previously only appeared in the television soap opera EastEnders for the fictional suburb of Walford . On 2 August 2011, it was announced the five neighbourhoods of housing and amenities (anti-clockwise from north-east) are: These names have relevant history in the area. All four of the East London boroughs covering the park as such have
7650-480: The park have been built on, replaced by cultural and commercial premises, as well as new housing. Stratford Park on West Ham Lane was laid out, in stages, by the County Borough of West Ham between 1899 and 1912. It was originally called West Ham Recreation Ground and is still known to many as West Ham Rec . The name was changed in 1999 to avoid confusion with nearby West Ham Park . In 1892–93, before
7752-403: The park in the London Borough of Tower Hamlets , the London Borough of Hackney and the London Borough of Waltham Forest . The park was prepared as the main venue of the 2012 Summer Olympics and permanently opened to the public in 2014. As part of the games and its legacy, the park included a number of sporting venues as well as extensive open spaces. Since the games many of the open parts of
7854-532: The park reopened in July 2013, while a large majority of the rest (including the Aquatics Centre, Velopark and Orbit observation tower) reopened in April 2014. The site covers parts of Stratford , Bow , Leyton , and Hackney Wick in east London , overlooking the A12 road . The site was previously a mixture of greenfield and brownfield land, including parts of Hackney Marshes . The Royal Mail gave
7956-558: The pleasure and health of the latter part of their days". An early industrial undertaking at Stratford was the Bow porcelain factory , which despite the name, was on the Essex side of the River Lea. Using a process that was patented in 1744, Edward Heylin and Thomas Frye operated a factory near Bow Bridge called "New Canton" to produce some of the first soft-paste porcelain to be made in
8058-583: The pole in use. In the latter case, the line from the converter station to the earthing (grounding) electrode is built as underground cable, as overhead line on a separate right of way or by using the ground conductors. Electrode line towers are used in some HVDC schemes to carry the power line from the converter station to the grounding electrode. They are similar to structures used for lines with voltages of 10–30 kV, but normally carry only one or two conductors. AC transmission towers may be converted to full or mixed HVDC use, to increase power transmission levels at
8160-737: The public grid or for the railway traction current grid. Concrete poles for medium-voltage are also used in Canada and the United States. In Switzerland, concrete pylons with heights of up to 59.5 metres (world's tallest pylon of prefabricated concrete at Littau ) are used for 380 kV overhead lines. In Argentina and some other south american countries, many overhead power lines, except the ultra-high voltage grid, were placed on tubular concrete pylons. Also in former soviet countries, concrete pylons are common, though with crossarms made of steel. Concrete pylons, which are not prefabricated, are also used for constructions taller than 60 metres. One example
8262-454: The pylons in order to prevent electrochemical corrosion of the pylons. For single-pole HVDC transmission with ground return, towers with only one conductor can be used. In many cases, however, the towers are designed for later conversion to a two-pole system. In these cases, often conductors on both sides of the tower are installed for mechanical reasons. Until the second pole is needed, it is either used as electrode line or joined in parallel with
8364-455: The realization of overhead 400/230 volt grids for the power supply of homes [1] . However, there are also roof-mounted support structures for high-voltage. Some thermal power plants in Poland like Połaniec Power Station and in the former Soviet Union like Lukoml Power Station use portal pylons on the roof of the power station building for the high voltage line from the machine transformer to
8466-516: The same towers is common. Sometimes, especially with 110 kV circuits, a parallel circuit carries traction lines for railway electrification . High-voltage direct current (HVDC) transmission lines are either monopolar or bipolar systems. With bipolar systems, a conductor arrangement with one conductor on each side of the tower is used. On some schemes, the ground conductor is used as electrode line or ground return. In this case, it had to be installed with insulators equipped with surge arrestors on
8568-469: The same width. In 2021 the first T-pylon, a new tubular T-shaped design, was installed in United Kingdom for a new power line to Hinkley Point C nuclear power station , carrying two high voltage 400 kV power lines. The design features electricity cables strung below a cross-arm atop a single pole which reduces the visual impact on the environment compared to lattice pylons. These 36 T-pylons were
8670-516: The second most significant business location in east London after Canary Wharf . Stratford's early significance was due to a Roman road (later known as the Great Essex Road ) running from Aldgate in the City , across the River Lea , to Romford , Chelmsford and Colchester . At that time the various branches of the river were tidal and without channels, while the marshes surrounding them had yet to be drained. The Lea Valley formed
8772-500: The soil across the Park site was cleaned down to a human health layer, by soil washing. In addition, at the time of the Olympic and Paralympic games: The park has been given over to a number of current and planned uses after the London 2012 Summer Olympics finished, such as: As of January 2021, several arts and creativity institutions are constructing outposts at the park as part of a £1.1billion development, including: Stratford Cross
8874-559: The surge voltage insulating properties of wood. As of 2012 , 345 kV lines on wood towers are still in use in the US and some are still being constructed on this technology. Wood can also be used for temporary structures while constructing a permanent replacement. Concrete pylons are used in Germany normally only for lines with operating voltages below 30 kV. In exceptional cases, concrete pylons are used also for 110 kV lines, as well as for
8976-519: The switchyard. Also other industrial buildings may have a rooftop powerline support structure. One can find such a device at a steel work in Dnipro, Ukraine at 48°28'57"N 34°58'43"E and at a steel work in Freital, Germany at 50°59'53"N 13°38'26"E. In the United States such device may be more common as in other countries [2] , [3] There are also real rooftop high voltage towers on industry buildings as at
9078-442: The top 32 meters of one of them being bent by 18 degrees to the vertical. Power station chimneys are sometimes equipped with crossbars for fixing conductors of the outgoing lines. Because of possible problems with corrosion by flue gases, such constructions are very rare. There exist also a variety of pylons and powerline poles mounted on buildings. The most common forms are small rooftop poles used in some countries like Germany for
9180-412: The top above or below the overhead ground wire . Usually these installations are for mobile phone services or the operating radio of the power supply firm, but occasionally also for other radio services, like directional radio. Thus transmitting antennas for low-power FM radio and television transmitters were already installed on pylons. On the Elbe Crossing 1 tower, there is a radar facility belonging to
9282-416: The upper arm carries one and the lower arm carries two cables on each side. Sometimes they have an additional cross arm for the protection cables. Ton shaped towers are the most common design, they have 3 horizontal levels with one cable very close to the pylon on each side. In the United Kingdom the second level is often (but not always) wider than the other ones while in the United States all cross arms have
9384-469: The use of monopolar steel or concrete towers over lattice steel for new power lines and tower replacements. 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. Steel tube pylons are also frequently used for 380 kV lines in France , and for 500 kV lines in
9486-517: The use of the venues for international events, some of them are intended for use on a regular basis by amateur and professional sports teams in various sports. On 11 February 2011, West Ham United were selected as preferred bidders, ahead of Tottenham Hotspur , to take over the Olympic Stadium as a football venue after the end of the games. However, five days later Leyton Orient chairman Barry Hearn announced that he would be challenging
9588-484: The world), increased Stratford's importance as a transport and manufacturing centre. Rising population levels led to two major new Anglican churches in the area, St John's Church in 1834 and Christ Church in 1851. Stratford station was opened on 20 June 1839 by the Eastern Counties Railway (ECR). The Northern and Eastern Railway opened a section of its authorised line from Broxbourne to join

The remaining indoor arenas are the Basketball Arena and the Copper Box , in addition to the Water Polo Arena , the Aquatics Centre , and the Velopark . The final design of the park was approved by the Olympic Delivery Authority and its planning-decisions committee. The Legacy List is the independent charity for Queen Elizabeth Olympic Park, set up in 2011 to support
9792-846: Was converted to a multi-use venue that will include use for basketball . As a result of the owners of the Prestige Homes Arena in Milton Keynes terminating their lease, the London Lions basketball club, after a season at the National Sports Centre , Selhurst , relocated to the Copper Box for the 2013-14 BBL season . The Lee Valley Hockey Centre was born from a revamp of the Olympic Legacy Hockey Facility . The facility
9894-595: Was erected on the marshy wastes of Stratford and Plaistow, and it only required the construction at Canning Town of the Victoria and Albert Docks to make the once desolate parish of West Ham a manufacturing and commercial centre of the first importance and to bring upon it a teeming and an industrious population." By the early 19th century, Stratford was an important transport hub, with omnibuses and coaches running into London four times every hour and coaches from East Anglia passing through hourly. The route into London

A small dock and a number of wharves were operating on the River Lea at Stratford by the 1820s, serving the needs of local industries. The opening of the Victoria Dock (later Royal Victoria Dock ) nearby on the Thames in 1855, and the subsequent construction of the Royal Group of Docks (at one time the largest area of impounded water in
10200-608: Was previously only used by the BBC TV soap EastEnders for its fictional East London setting of Walford . The name "Walford" is a portmanteau of the names of nearby Walthamstow and Stratford itself. Stratford was one of three ancient wards in the large ancient parish of West Ham , in the Becontree hundred of Essex . It came within the Metropolitan Police District in 1840. Despite forming part of
10302-534: Was revealed in 1849, the settlement quickly became better known as Stratford New Town , which by 1862 had a population of 20,000. During the lifetime of the Stratford works, 1,682 locomotives , 5,500 passenger coaches and 33,000 goods wagons were built. The last part of the works closed in March 1991. Stratford, like many areas of London, particularly in the East End, suffered significant de-industrialisation in
