Osaki Channel Crossing
The Osaki Channel Crossing is a power line crossing over Seto Inland Sea south of Yoshina, Takehara in Japan, 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 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, Honsh ..., 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 Li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Power Line
An overhead power line is a structure used in electric power transmission and distribution to transmit electrical energy across large distances. It consists of one or more uninsulated electrical cables (commonly multiples of three for three-phase power) suspended by towers or poles. Since most of the insulation is provided by the surrounding air, overhead power lines are generally the least costly method of power transmission for large quantities of electric energy. Construction Towers for support of the lines are made of wood either 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 reinforced with steel or composite materials such as carbon and glass fiber), though some copper wires are used in medium-voltage distribution and low-voltage connections to customer premises. A major goal of overhead power line d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seto Inland Sea
The , sometimes shortened to the Inland Sea, is the body of water separating Honshū, Shikoku, and Kyūshū, 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.

Takehara, Hiroshima
is a city located in Hiroshima Prefecture, Japan. The city was founded on November 3, 1958. As of 2016, the city has an estimated population of 26,035 and a population density of 220 persons per km2. The total area is 118.30 km2. Ōkunoshima, the island where a poison gas plant of the Imperial Japanese Army was located, belongs to Takehara. Occupying a strategic location on the Seto Inland Sea, it became renowned as a port city in the Muromachi period and then flourished as a centre of the salt industry in the latter days of the Edo period. More recently, it has styled itself as "The Little Kyoto of Aki" and the Special Historical District of old warehouses was selected as one of Japan's "100 Most Scenic Towns". Geography Climate Takehara has a humid subtropical climate (Köppen climate classification ''Cfa'') characterized by cool to mild winters and hot, humid summers. The average annual temperature in Takehara is . The average annual rainfall is with July as the wett ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Japan
Japan ( ja, 日本, or , and formally , ''Nihonkoku'') is an island country in East Asia. It is situated in the northwest Pacific Ocean, and is bordered on the west by the Sea of Japan, while extending from the Sea of Okhotsk in the north toward the East China Sea, Philippine Sea, and Taiwan in the south. Japan is a part of the Ring of Fire, and spans Japanese archipelago, an archipelago of List of islands of Japan, 6852 islands covering ; the five main islands are Hokkaido, Honshu (the "mainland"), Shikoku, Kyushu, and Okinawa Island, Okinawa.

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 Inland Sea of Japan. It is considered to be part of the city of Takehara, Hiroshima Prefecture. It is accessible by ferry from Tadanoumi and Ōmishima. There are campsites, walking trails and places of historical inte ... 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 known as an electricity pylon or simply a pylon in British English and as a hydro tower in Canadian English, is a tall structure, usually a steel lattice tower, used to support an overhead power line. In electrical grids, they are generally used to carry high-voltage transmission lines that transport bulk electric power from generating stations to electrical substations; utility poles are used to support lower-voltage subtransmission and distribution lines that transport power from substations to electric customers. They come in a wide variety of shapes and sizes. Typical height ranges from , though the tallest are the towers of a span between the islands Jintang and Cezi in China's Zhejiang province. The longest span of any hydroelectric crossing ever built belongs to Ameralik Span, the powerline crossing of Ameralik fjord with a length of . In addition to steel, other materials may be used, including concrete and wood. There are four major categ ... [...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, ...
