Osaki Channel Crossing
The Osaki Channel Crossing is a power line crossing over Seto Inland Sea south of Yoshina, Takehara in Japan Japan is an island country in East Asia. Located in the Pacific Ocean off the northeast coast of the Asia, Asian mainland, it is bordered on the west by the Sea of Japan and extends from the Sea of Okhotsk in the north to the East China Sea ..., which was built in 1997 and runs from Chugoku Electric Power's Ozaki Power Station at to the Japanese Mainland at , with two water crossings: the Nagashima Sector, connecting the Power Station to Usujima, with a span width of 1603 metres, and the Yoshina Sector, which spans from Usujima to the mainland at 2145 metres long. At a height of 223 metres, the towers of the Yoshina Sector are just 3 metres shorter than those of the Chūshi Powerline Crossing, making them the second-tallest electricity pylons in Japan. The pylons follow a barrel design with 3 crossbars. These sectors are part of the greater Osaki Thermal Power Lin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Power Line
An overhead power line is a structure used in electric power transmission and Electric power distribution, distribution to transmit electrical energy along large distances. It consists of one or more electrical conductor, conductors (commonly multiples of three) suspended by Transmission tower, towers or Utility pole, poles. Since the surrounding air provides good cooling, electrical insulation, insulation along long passages, and allows optical inspection, overhead power lines are generally the lowest-cost method of power transmission for large quantities of electric energy. Construction Towers for support of the lines are made of wood (as-grown or laminated), steel or aluminum (either lattice structures or tubular poles), concrete, and occasionally reinforced plastics. The bare wire conductors on the line are generally made of aluminum (either plain or ACSR, reinforced with steel, or composite materials such as carbon and glass fiber), though some copper wires are used in ...

Seto Inland Sea
The , sometimes shortened to the Inland Sea, is the body of water separating Honshu, Shikoku, and Kyushu, three of the four main islands of Japan. It serves as a waterway connecting the Pacific Ocean to the Sea of Japan. It connects to Osaka Bay and provides a sea transport link to industrial centers in the Kansai region, including Osaka and Kobe. Before the construction of the San'yō Main Line, it was the main transportation link between Kansai and Kyūshū. Yamaguchi, Hiroshima, Okayama, Hyōgo, Osaka, Wakayama, Kagawa, Ehime, Tokushima, Fukuoka, and Ōita prefectures have coastlines on the Seto Inland Sea; the cities of Hiroshima, Iwakuni, Takamatsu, and Matsuyama are also located on it. The Setouchi region encompasses the sea and surrounding coastal areas. The region is known for its moderate climate, with a stable year-round temperature and relatively low rainfall levels. The sea experiences periodic red tides caused by dense groupings of certain phytoplankton th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chūshi Powerline Crossing
The Chūshi Powerline Crossing is a part of the , a 220 kV powerline in Japan. It has two circuits running over the Inland Sea from Takehara. It was built in 1962 and consists of two towers, each 226 metres tall, one situated in Takehara, Honshū at , the other on the island of Ōkunoshima is a small island in the Seto Inland Sea, Inland Sea of Japan. It is considered to be part of the city of Takehara, Hiroshima, Takehara, Hiroshima Prefecture. It is accessible by ferry from Tadanoumi and Ōmishima Island, Ehime, Ōmishima. The ... at . These towers are the tallest electricity pylons in Japan and carry six conductors arranged in three levels. The span between the two towers has a length of 2,357 metres and has a minimum clearance of 42 metres. The conductors have a cross section of 170 mm2, a diameter 35.2 mm and are designed for a maximum current of 645 A.

Transmission Tower
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. There are four categories of transmission towers: (i) the suspension tower, (ii) the dead-end terminal tower, (iii) the tension tower, and (iv) the transposition tower. The heights of transmission towers typically range from , although when longer spans are needed, such as for crossing water, taller towers are sometimes used. More transmission towers are needed to mitigate climate change, and as a result, transmiss ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Towers In Japan
A tower is a tall structure, taller than it is wide, often by a significant factor. Towers are distinguished from masts by their lack of guy-wires and are therefore, along with tall buildings, self-supporting structures. Towers are specifically distinguished from buildings in that they are built not to be habitable but to serve other functions using the height of the tower. For example, the height of a clock tower improves the visibility of the clock, and the height of a tower in a fortified building such as a castle increases the visibility of the surroundings for defensive purposes. Towers may also be built for observation, leisure, or telecommunication purposes. A tower can stand alone or be supported by adjacent buildings, or it may be a feature on top of a larger structure or building. Etymology Old English ''torr'' is from Latin ''turris'' via Old French ''tor''. The Latin term together with Greek τύρσις was loaned from a pre-Indo-European Mediterranean language, ...
