List Of Spans
The following is a list of spans, either used for overhead line crossings of rivers, sea straits or valleys, as antenna or for aerial tramways. Powerline spans in flat areas with high pylons At these spans the sag of the conductors is less than the height of the pylons Powerline spans in mountainous areas requiring shorter pylons At these spans, the pylons are situated on the tops of mountains, so the topography determines the height of the lines. Because of this it is possible that the span pylons can be lower than the height of the line at point of largest sag. Antenna spans across valleys Aerial tramways Rope Tyroleans Other See also * List of longest suspension bridge spans * List of longest cantilever bridge spans * Timeline of three longest spans References {{Reflist Spans (architecture), * Lists of construction records ...

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 constructed. Overhead line crossings can sometimes require extensive construction and can also have operational issues. In such cases, those in charge of construction should consider whether a crossing of the obstacle would be better accomplished by an underground or submarine cable. Crossings of roads and railway lines Overhead line crossings of roads, railway lines, and small- and medium-sized watercourses do not normally require special construction. However, in the first years building overhead line when crossing a railway line or a road, a scaffold under the line was required. Later in Germany and some other countries on each end of a powerline crossing of a state-operated railway, a dead-end tower was required, which can still ...

Guangdong
) means "wide" or "vast", and has been associated with the region since the creation of Guang Prefecture in AD 226. The name "''Guang''" ultimately came from Guangxin ( zh, labels=no, first=t, t= , s=广信), an outpost established in Han dynasty near modern Wuzhou, whose name is a reference to an order by Emperor Wu of Han to "widely bestow favors and sow trust".

Yangtze River Power Line Crossings
The Yangtze River power line crossings are overhead power lines that cross the Yangtze River in China. There are at least three power line crossings on the Yangtze River at Jiangyin, Nanjing, and Wuhu. The towers of the crossing in Jiangyin are among the highest in the world. Jiangyin One exists at Jiangyin, Jiangsu Province, China. Each pylon is situated at and at . It is a section of the 500 kV power line from the Yancheng power station to the Dou Shan substation in the province of Jiangsu. The power line section running over the river has a span width of . It is carried by two tall suspension towers, each weighing 4,192 tonnes. (for comparison, the towers even surpass the height of the Eiffel Tower, which is , including antenna). They are identical lattice towers of square cross section with an area of × 68 m at the base and × 8 m at the top. The pylons carry four conductors on the lower crossarm, above ground, with a length of and two conductors on the upper cro ...

Pylons Of Messina
The Pylons of Messina are two free-standing steel towers, the Sicilian one in Torre Faro and the Calabrian one in Villa San Giovanni. They were used from 1955 to 1994 to carry a 220 kilovolt (150 kilovolt until 1971) overhead power line, power line across the Strait of Messina, between the Scilla, Calabria, Scilla substation in Calabria on the Italian mainland at and the Messina-Santo substation in Sicily at . Design The two pylons, built in 1955, are both free-standing steel towers. Each stands on an cross-shaped base and is equipped with a crossbar that carries four conductors at a height of , and another V-shaped structure at the top which carries two additional conductors in addition to ground wires. In contrast to more conventional pylon design, the corners of the pylons are arranged diagonally along the direction of the course of the line. The pylons of Messina were the model for the Electricity sector in Germany#Powerline crossings of Elbe river near Stade, Elbe Cross ...
