Cables usually are secured with special fittings where they enter electrical apparatus; this may be a simple screw clamp for jacketed cables in a dry location, or a polymer-gasketed cable connector that mechanically engages the armour of an armoured cable and provides a water-resistant connection.
Several other types of wiring systems are used for building wiring in the United States; these include corrugated metal armored cable, mineral-insulated cable, other types of power cable, and various types of electrical conduit. In industrial applications cables may be laid in cable trays. Cable type TC is especially intended for use in tray ...
In electrical power distribution, armoured cable usually means steel wire armoured cable (SWA) which is a hard-wearing power cable designed for the supply of mains electricity. It is one of a number of armoured electrical cables – which include 11 kV Cable and 33 kV Cable – and is found in underground systems, power networks and cable ducting.
A similar, usually wall mounted, container used mainly to accommodate switches, sockets and the associated connecting wiring is called a pattress. The term junction box may also be used for a larger item, such as a piece of street furniture. In the UK, such items are often called a cabinet. See Enclosure (electrical).
It has advantages over armored building cable because it is lighter, easier to handle, and its sheathing is easier to work with. [10] Power cables use stranded copper or aluminum conductors, although small power cables may use solid conductors in sizes of up to 1/0. (For a detailed discussion on copper cables, see: Copper wire and cable.). The ...
In response to industry demand, CSA has developed Part IV of the Canadian Electrical Code, consisting of two standards CSA C22.4 No. 1 "Objective-based industrial electrical code" and CSA C22.4 No. 2 "Objective-based industrial electrical code - Safety management system requirements".
Teck cable is a type of low voltage armoured cable named for the location where it was first developed and used, Teck Township, now known as Kirkland Lake, Ontario. The mining operations such as those conducted by Teck-Hughes Gold Mining Ltd. required a durable cable to power equipment and withstand the demanding conditions, and teck cable was ...
High voltage is defined as any voltage over 1000 volts. [3] Those of 2 to 33 kV are usually called medium voltage cables, those over 50 kV high voltage cables.. Modern HV cables have a simple design consisting of a few parts: the conductor, the conductor shield, the insulation, the insulation shield, the metallic shield, and the jacket.
