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.
Power cables often need to be grouped separately and suitably apart from data cables, and only cross at right angles which minimizes electromagnetic interference. The organized routing of cables inside the computer case allows for optimal airflow and cooling. Good cable management also makes working inside a computer much easier by providing ...
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 ...
An electrical cable is an assembly of one or more wires running side by side or bundled, which is used as an electrical conductor to carry electric current. Electrical cables are used to connect two or more devices, enabling the transfer of electrical signals, power, or both from one device to the other. Physically, an electrical cable is an ...
Coaxial cable, an electrical cable comprising an inner conductor surrounded by a flexible, tubular insulating layer, coated or surrounded by a tubular conducting shield; Power cable, a cable used to transmit electrical power; Submarine communications cable, a cable laid on the sea bed to carry telecommunication signals between land-based stations
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.
A ribbon cable is a cable with many conducting wires running parallel to each other on the same flat plane. As a result, the cable is wide and flat. Its name comes from its resemblance to a piece of ribbon. [1] Ribbon cables are usually seen for internal peripherals in computers, such as hard drives, CD drives and floppy drives.
The conduit methods were known to be of better quality, but cost significantly more than K&T. [2] In 1909, flexible armored cable cost about twice as much as K&T, and conduit cost about three times the price of K&T. [6] Knob and tube wiring persisted since it allowed owners to wire a building for electricity at lower cost.
