Assembled single stranded wire - cable assembling
In electrical engineering, the stranded wire (also stranded cable, single core, single strand or stranded wire) consists of several thin individual wires. The individual wires are formed into a stranded wire by stranding or strangling. For this reason, this electrical conductor can be easily bent. In electrical standards, terms such as fine-stranded conductor or finest-stranded conductor are also used.
The individual wires (there can be up to several hundred) of the stranded wire are enclosed in a sheath. Such conductors are called stranded cables/stranded conductors. If several such stranded conductors are combined in one cable, they are called cores.
Since the individual strands can be bent easily, the risk of a line breakage is lower compared to rigid lines. For this reason, stranded cables are primarily used for cables that are frequently exposed to movements and vibrations. Likewise, stranded cables are often used for power supply lines of mobile devices.
If stranded cables are to be connected in e.g. terminals, wire end ferrules must be applied to the individual wires to protect them from mechanical damage to the terminal screw. In the case of terminal designs such as lift terminals or spring-loaded terminals, there is no need for a wire-end ferrule. If stranded wires are to be connected to the control cabinet door (PE / protective earth), for example, they must be fitted with a cable lug (e.g. crimped cable lug ring type).
Tinning of stranded wires has proven to be unreliable, as the poor contact properties (oxidation) of the tin can lead to loosening and interruption or to a high current density in the terminal and thus ultimately to an arc fault resulting in fire damage.
