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 for ...

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 equipment'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 operati ...

Mains Power Plug
AC power plugs and sockets connect devices to mains electricity to supply them with electrical power. A plug is the connector attached to an electrically operated device, often via a cable. A socket (also known as a receptacle or outlet) is fixed in place, often on the internal walls of buildings, and is connected to an Alternating current, AC electrical circuit. Inserting ("plugging in") the plug into the socket allows the device to draw power from this circuit. Plugs and wall-mounted sockets for portable appliances became available in the 1880s, to replace connections to light sockets. A proliferation of types were subsequently developed for both convenience and protection from electrical injury. Electrical plugs and sockets differ from one another in voltage and electric current, current rating, shape, size, and connector type. Different standard systems of plugs and sockets are used around the world, and many obsolete socket types are still found in older buildings. Coordi ...

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 1363, ''13 A plugs socket-outlets adaptors and connection units'' is a British Standard which specifies the most common type of single-phase AC power plugs and sockets that are used in the United Kingdom. Distinctive characteristics of the system are shutters on the neutral and (see below) socket holes, and a fuse in the plug. It has been adopted in many former British colonies and protectorates. BS 1363 was introduced in 1947 as one of the new standards for electrical wiring in the United Kingdom used for post-war reconstruction. The plug and socket replaced the BS ...

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 malSocapexconnector with six "tails" with female connectors such as parallel blade receptacle, stage pin connector, IEC 60309 16 A, NEMA L5-20P & L6-20P 'twist-lock', BS 546 15 A, PowerCon or Schu ...

Multicable
In stage lighting, Stage Lighting Design Principle and Process 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, 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 [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 outer ... [...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 IECEE, CEE 17, also published by European Committee for Electrotechnical Standardization, 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 referred to as "pin & sleeve" connectors in North America or as "CeeForm" connectors in the entertainment industry. The maximum voltage allowed by the standard is direct current, DC or alternating current, AC; the maximum Current (electricity), 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-a ...

London Underground
The London Underground (also known simply as the Underground or as the Tube) is a rapid transit system serving Greater London and some parts of the adjacent home counties of Buckinghamshire, Essex and Hertfordshire in England. The Underground has its origins in the Metropolitan Railway, opening on 10 January 1863 as the world's first underground passenger railway. The Metropolitan is now part of the Circle line (London Underground), Circle, District line, District, Hammersmith & City line, Hammersmith & City and Metropolitan lines. The first line to operate underground electric locomotive, electric traction trains, the City & South London Railway in 1890, is now part of the Northern line. The network has expanded to 11 lines with of track. However, the Underground does not cover most southern parts of Greater London; there are only 33 Underground stations south of the River Thames. The system's List of London Underground stations, 272 stations collectively accommodate up ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shopping Mall
A shopping mall (or simply mall) is a large indoor shopping center, usually Anchor tenant, anchored by department stores. The term ''mall'' originally meant pedestrian zone, a pedestrian promenade with shops along it, but in the late 1960s, it began to be used as a generic term for the large enclosed shopping centers that were becoming increasingly commonplace. In the United Kingdom and other countries, shopping malls may be called ''shopping centres''. In recent decades, malls have declined considerably in North America, partly due to the retail apocalypse, particularly in subprime locations, and some have closed and become so-called "dead malls". Successful exceptions have added entertainment and experiential features, added big-box stores as anchors, or converted to other specialized shopping center formats such as power center (retail), power centers, lifestyle centers, factory outlet centers, and festival marketplaces. In Canada, shopping centres have frequently been repl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
