Industrial And Multiphase Power Plugs And Sockets
Industrial and multiphase plugs and sockets provide a connection to the electrical mains rated at higher voltages and currents than household plugs and sockets. They are generally used in polyphase systems, with high currents, or when protection from environmental hazards is required. Industrial outlets may have weatherproof covers, waterproofing sleeves, or may be interlocked with a switch to prevent accidental disconnection of an energized plug. Some types of connectors are approved for hazardous areas such as coal mines or petrochemical plants, where flammable gas may be present. Almost all three-phase power plugs have an earth (ground) connection, but may not have a neutral because three-phase loads such as motors do not need the neutral. Such plugs have only four prongs (earth, and the three phases). An example of a socket with neutral is the L21-30 (30 A) and the L21-20 (20 A) both of which have five pins (earth, neutral, and X, Y, Z phases). While some forms ...

Protective Earth
An earthing system (UK and IEC) or grounding system (US) connects specific parts of an electric power system with the ground, typically the Earth's conductive surface, for safety and functional purposes. The choice of earthing system can affect the safety and electromagnetic compatibility of the installation. Regulations for earthing systems vary among countries, though most follow the recommendations of the International Electrotechnical Commission (IEC). Regulations may identify special cases for earthing in mines, in patient care areas, or in hazardous areas of industrial plants. In addition to electric power systems, other systems may require grounding for safety or function. Tall structures may have lightning rods as part of a system to protect them from lightning strikes. Telegraph lines may use the Earth as one conductor of a circuit, saving the cost of installation of a return wire over a long circuit. Radio antennas may require particular grounding for operation, as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mains Power Plug
AC power plugs and sockets connect electric equipment to the alternating current (AC) mains electricity power supply in buildings and at other sites. Electrical plugs and sockets differ from one another in voltage and current rating, shape, size, and connector type. Different standard systems of plugs and sockets are used around the world. Plugs and sockets for portable appliances became available in the 1880s, to replace connections to light sockets with wall-mounted outlets. A proliferation of types developed for both convenience and protection from electrical injury. Today there are about 20 types in common use around the world, and many obsolete socket types are found in older buildings. Coordination of technical standards has allowed some types of plug to be used across large regions to facilitate trade in electrical appliances, and for the convenience of travellers and consumers of imported electrical goods. Some multi-standard sockets allow use of several types of plug; ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BS 1363
Plugs and sockets for electrical appliances not hardwired to mains electricity originated in the United Kingdom in the 1870s and were initially two-pin designs. These were usually sold as a mating pair, but gradually de facto and then official standards arose to enable the interchange of compatible devices. British standards have proliferated throughout large parts of the former British Empire. BS 546, ''Two-pole and earthing-pin plugs, socket-outlets and socket-outlet adaptors for AC (50–60 Hz) circuits up to 250 V'' is a British Standard for three-pin AC power plugs and sockets. Originally published in April 1934, it was updated by a 1950 edition which is still current, with eight amendments up to 1999. BS 546 is also the precursor of current Indian and South African plug standards. The 5 A version has been designated as ''Type D'' and the 15 A as ''Type M'' in the IEC 60083 plugs and sockets standard. BS 546 plugs and sockets are ...

Socapex
Socapex is a brand of electrical connectors, known in the entertainment industry primarily for their 19-pin electrical connectors, commonly known as Socapex connectors, and used in film, television, and stage lighting to terminate the ends of a multicable. They are wired with six hot/live pins, six neutral pins, six ground/earth pins, and a final central pin used to aid alignment of the male end of the connector with a female receptacle. The Socapex was first created by a company called Socapex in 1961, which later on became Amphenol Socapex. "Socapex" became a brand name owned by Amphenol Socapex, the term "Soca" is now often applied to similar off-brand connectors as a genericized trademark. "Breakouts" are often used to connect fixtures to the cable. The breakout consists of a male Socapex connector with six "tails" with female parallel blade receptacle, stage pin connector, IEC 60309 16 A, NEMA L5-20P & L6-20P 'twist-lock', BS 546 15 A, PowerCon or Schuko "Schuko" ...

Multicable
{{Globalize, date=February 2018 In stage lighting, a multicable (otherwise known as multi-core cable or mult) is a type of heavy-duty electrical cable used in theaters to power lights. The basic construction involves a bundle of individual conductors surrounded by a single outer jacket. Whereas single cables only have three conductors, multicable has ten or more. They are configured to run in six or eight-circuit varieties. Typically, both ends of multicable have a specific connector known as a Socapex Connector. Technicians then combine the cables with break-outs and break-ins, which essentially are an octopus-like adapter with one Socapex end and six to eight Edison, twist-lok, or stage pin style connectors. Use Multicable is used when technicians need to mount lights where no permanent circuiting options exist. Typically, mounting pipes designed for lighting use have enclosed raceways with permanent power outlets, running to a remote dimmer unit somewhere in the theater. Wh ...

Camlock (electrical)
A camlock or ''cam-lock'' is an interchangeable electrical connector, often used in temporary electrical power production and distribution, predominantly in North America. Originally a trade name as ''Cam-Lok'', it is now a generic term. Each camlock connector carries a single phase, pole, or conductor; multiple camlock connectors will be used to make a complete electrical supply or circuit. The most common form is the ''16'' series, rated at 400 amperes with 105 °C terminations. Also in common use is the ''15'' series (''mini-cam''), rated at 150 amperes. A larger version is made denoted as the ''17'' series with ratings up to 760 A. A ball nose version and a longer nose standard version exist—the latter is the most common. The early version original connector was hot-vulcanized to the cable body; later versions use dimensional pressure to exclude foreign material from the connector pin area. The tail of the connector insulator body is trimmable to fit the cable out ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Powerlock
Powerlock is a range of single-pole electrical connectors used for temporary high-current, low-voltage (up to 1000 V AC) applications, similar to but considered safer than camlock connectors. Originally developed by Litton Veam in the mid-1990s, VEAM Powerlock is now a brand of ITT Cannon. Compatible versions are also available from other manufacturers. Powerlock connectors are available in 400 A and 660 A versions. All versions can be used for single-phase and, much more commonly, three-phase applications. Three phase connections require five separate cables (or four if neutral is not required). Applications Single-pole power connectors are employed for making electrical power connections where multi-pole connectors and cables would be impractical to handle due to size, weight and cable bend radius. They are typically used for connecting to large generators and fixed power sources in venues where high-powered temporary equipment may be regularly used. Powerlock inputs ar ...

IEC 60309
IEC 60309 (formerly IEC 309 and CEE 17, also published by CENELEC as EN 60309) is a series of international standards from the International Electrotechnical Commission (IEC) for "plugs, socket-outlets and couplers for industrial purposes". They are also used in the entertainment industry where they are commonly referred to as "CeeForm" connectors. The maximum voltage allowed by the standard is DC or AC; the maximum current, ; and the maximum frequency, . The ambient temperature range is to . There is a range of plugs and sockets of different sizes with differing numbers of pins, depending on the current supplied and number of phases accommodated. Connectors generally are specified by the voltage and current ratings, general configuration (number of pins), and rotational alignment ("keying"). The fittings are popular in open-air conditions, as the connectors have a minimum IP44 weather-proofing rating. They are also sometimes used in situations where their speci ...

London Underground
The London Underground (also known simply as the Underground or by its nickname the Tube) is a rapid transit system serving Greater London and some parts of the adjacent counties of Buckinghamshire, Essex and Hertfordshire in England. The Underground has its origins in the Metropolitan Railway, the world's first underground passenger railway. Opened on 10 January 1863, it is now part of the Circle, District, Hammersmith & City and Metropolitan lines. The first line to operate underground electric traction trains, the City & South London Railway in 1890, is now part of the Northern line. The network has expanded to 11 lines, and in 2020/21 was used for 296 million passenger journeys, making it one of the world's busiest metro systems. The 11 lines collectively handle up to 5 million passenger journeys a day and serve 272 stations. The system's first tunnels were built just below the ground, using the cut-and-cover method; later, smaller, roughly circular tu ...

Shopping Mall
A shopping mall (or simply mall) is a North American term for a large indoor shopping center, usually anchored by department stores. The term "mall" originally meant a pedestrian promenade with shops along it (that is, the term was used to refer to the walkway itself which was merely bordered by such shops), but in the late 1960s, it began to be used as a generic term for the large enclosed shopping centers that were becoming commonplace at the time. In the U.K., such complexes are considered shopping centres (Commonwealth English: shopping centre), though "shopping center" covers many more sizes and types of centers than the North American "mall". Other countries may follow U.S. usage (Philippines, India, U.A.E., etc.) and others (Australia, etc.) follow U.K. usage. In Canadian English, and oftentimes in Australia and New Zealand, 'mall' may be used informally but 'shopping centre' or merely 'centre' will feature in the name of the complex (such as Toronto Eaton Centre).
