Kootenay Lake Crossing
Kootenay Lake Crossing is a powerline crossing of Kootenay Lake, British Columbia, Canada. The idea was to transport electricity from the Hydro dam on the Kootenay River at Brilliant to the Cominco Sullivan Mine at Kimberley. The most direct route was across Kootenay Lake. Originally it was with a span width of the longest powerline span of North America and fixed on three - for each conductor a single one - 19 metres tall towers at the west shore and a tall electricity pylon on the east shore. This tower was erected in spite of high mountains on the east shore for building short towers were available, as erecting span terminal towers on them would have required a longer span, for which the use of spliced conductors were required, which was undesired as the splicing point is a potential point of failure. Roebling cable provided the steel support cable for the conductor. The height of conductor over Kootenay Lake was . Kootenay Lake Crossing was inaugurated in 1952, but on March 8 ...

Kootenay Lake
Kootenay Lake is a lake located in British Columbia, Canada. It is part of the Kootenay River. The lake has been raised by the Corra Linn Dam and has a dike system at the southern end, which, along with industry in the 1950s–70s, has changed the ecosystem in and around the water. The Kootenay Lake ferry is a year-round toll-free ferry that crosses between Kootenay Bay and Balfour. The lake is a popular summer tourist destination. Geography Kootenay Lake is a long, narrow and deep fjord-like lake located between the Selkirk and Purcell mountain ranges in the Kootenay region of British Columbia. It is one of the largest lakes in British Columbia, at 104 km in length and 3–5 km in width. It is, in part, a widening of the Kootenay River, which in turn drains into the Columbia River system at Castlegar, British Columbia. Although oriented primarily in a north-south configuration, a western arm positioned roughly halfway up the length of the lake stretches 35&nb ...

British Columbia
British Columbia (commonly abbreviated as BC) is the westernmost province of Canada, situated between the Pacific Ocean and the Rocky Mountains. It has a diverse geography, with rugged landscapes that include rocky coastlines, sandy beaches, forests, lakes, mountains, inland deserts and grassy plains, and borders the province of Alberta to the east and the Yukon and Northwest Territories to the north. With an estimated population of 5.3million as of 2022, it is Canada's third-most populous province. The capital of British Columbia is Victoria and its largest city is Vancouver. Vancouver is the third-largest metropolitan area in Canada; the 2021 census recorded 2.6million people in Metro Vancouver. The first known human inhabitants of the area settled in British Columbia at least 10,000 years ago. Such groups include the Coast Salish, Tsilhqotʼin, and Haida peoples, among many others. One of the earliest British settlements in the area was Fort Victoria, established ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canada
Canada is a country in North America. Its ten provinces and three territories extend from the Atlantic Ocean to the Pacific Ocean and northward into the Arctic Ocean, covering over , making it the world's second-largest country by total area. Its southern and western border with the United States, stretching , is the world's longest binational land border. Canada's capital is Ottawa, and its three largest metropolitan areas are Toronto, Montreal, and Vancouver. Indigenous peoples have continuously inhabited what is now Canada for thousands of years. Beginning in the 16th century, British and French expeditions explored and later settled along the Atlantic coast. As a consequence of various armed conflicts, France ceded nearly all of its colonies in North America in 1763. In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federal dominion of four provinces. This began an accretion of provinces an ...

Span (architecture)
Span is the distance between two intermediate supports for a structure, e.g. a beam (structure), beam or a bridge. A span can be closed by a solid beam or by a rope. The first kind is used for bridges, the second one for power lines, overhead telecommunication lines, some type of Antenna (radio), antennas or for aerial tramways. The span is a significant factor in finding the strength and size of a beam as it determines the maximum bending moment and Deflection (engineering), deflection. The maximum bending moment M_ and deflection \delta_in the pictured beam is found using: :M_ = \frac :\delta_ = \frac = \frac where :q = Uniformly distributed load :L = Length of the beam between two supports (span) :E = Modulus of elasticity :I = Area moment of inertia Note that the maximum bending moment and deflection occur midway between the two supports. From this it follows that if the span is doubled, the maximum moment (and with it the tensile stress, stress) will quadruple, and ...

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 * Architectural structure Architectural engineers apply and theoretical knowledge to the engineering design of buildings and building systems. The goal is to engineer high performance buildings that are sustainable, economically viable and ensure the safety health. Archi ... * Timeline of three longest spans Referenc ...

North America
North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. Because it is on the North American Plate, North American Tectonic Plate, Greenland is included as a part of North America geographically. North America covers an area of about , about 16.5% of Earth's land area and about 4.8% of its total surface. North America is the third-largest continent by area, following Asia and Africa, and the list of continents and continental subregions by population, fourth by population after Asia, Africa, and Europe.

Electricity Pylon
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 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 categories of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Freedomites
The Freedomite movement consists of a split-off of the Doukhobors, a community of Spiritual Christians began a mass migration from Russia to Canada in 1898. The Freedomite movement first appeared in 1902 in Saskatchewan, and later in the Kootenay and Boundary Districts of British Columbia. Freedomites began to divide from Doukhobors in 1902 in Saskatchewan, Canada, self-named as "God's people" and ''Svobodniki'' (Russian: "sovereign people"). The faction, later called "Freedomites", opposed land ownership, public schools, using work animals, etc. and are mainly known for protesting nude. By 1920 the common English term for them became Sons of Freedom. Of about 20,000 active Doukhobors in Canada today, ancestors of about 2,500 were Freedomites,F.M.

Doukhobor
The Doukhobours or Dukhobors (russian: духоборы / духоборцы, dukhobory / dukhobortsy; ) are a Spiritual Christian ethnoreligious group of Russian origin. They are one of many non-Orthodox ethno-confessional faiths in Russia and are often categorized as "folk-Protestants", Spiritual Christians, sectarians, and heretics. Doukhobours are pacifist Christians who lived in their own villages, rejected personal materialism, worked together, and developed a tradition of oral history, memorizing, hymn-singing, and verse. Before 1886, the Doukhobors had a series of single leaders. The origin of the Doukhobors is uncertain; they first appear in first written records from 1701, although some scholars suspect the group has earlier origins. Doukhobors reject the Russian Orthodox priesthood, the use of icons, and all associated church rituals. Doukhobors believe the Bible alone is not enough to reach divine revelation and that doctrinal conflicts can interfere with their ...

Electric Power Transmission Systems In Canada
Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of an electric charge, which can be either positive or negative, produces an electric field. The movement of electric charges is an electric current and produces a magnetic field. When a charge is placed in a location with a non-zero electric field, a force will act on it. The magnitude of this force is given by Coulomb's law. If the charge moves, the electric field would be doing work on the electric charge. Thus we can speak of electric potential at a certain point in space, which is equal to the work done by an external agent in carrying a unit of positiv ...

West Kootenay
The Kootenays or Kootenay ( ) is a region of southeastern British Columbia. It takes its name from the Kootenay River, which in turn was named for the Kutenai First Nations people. Boundaries The Kootenays are more or less defined by the Kootenay Land District, though some variation exists in terms of what areas are or are not a part. The strictest definition of the region is the drainage basin of the lower Kootenay River from its re-entry into Canada near Creston, through to its confluence with the Columbia at Castlegar ''(illustrated by a, right)''. In most interpretations, however, the region also includes: * an area to the east which encompasses the upper drainage basin of the Kootenay River from its rise in the Rocky Mountains to its passage into the United States at Newgate. This adds a region spanning from the Purcell Mountains to the Alberta border, and includes Rocky Mountain Trench cities such as Cranbrook and Kimberley and the Elk Valley of the southern Canadi ...
