Solid Core Cable This type of cable uses one solid copper wire per conductor and is used for permanent infrastructure links between two wiring centres or between a wiring centre and a wall box. It has a lower attenuation and is less costly than stranded cable, however it is designed for horizontal and vertical structured cabling and it should not be flexed once installed. Stranded Cable Stranded cable consists of multiple strands of wires wrapped around each other in each conductor. Stranded cable is much more flexible and consequently suited to applications which demand flexibility and reshaping. Due to higher attenuation, stranded cable is better used over shorter distances. Flexible Cable Flexible cables, or 'continuous-flex' cables, are electrical cables specially designed to cope with the tight bending radii and physical stress associated with moving applications, such as inside cable carriers.
