Why do wires consist of many fine copper wires instead of a thick copper wire?
There is a coarse copper wire! Both exist. The difference between single stranded copper wire and multi strand copper wire is different in its structure, the multi strand copper wire is soft, not easy to break the line core, it is suitable for the conductor to follow the movement of the situation (such as the general distribution box, cabinet door), a plurality of wire laying together (for wire laying occasions and the wire beam forming).
In comparison with single stranded conductors, multiple strands are usually used for control lines. The single stranded conductor because of its structure, the corresponding comparison of multi wire high hardness, generally used for fixed installations (such as wear lines etc.), single strand copper wires multi strand copper wires, it is on the line connector, wiring more convenient equipment, multi strand copper wire must be pressed or welded wire nose etc..
Wires are divided into single strands and multiple strands, that is, one of the two thick and many thin roots you call. The performance is slightly better than that of single wire conductive strands, but soft and poor toughness, and is suitable for the installation of wire strands, soft with good toughness, suitable for wire inserted tube wiring installation!
Many of the fine copper wire, wire thread is similar, is soft, 2 stranded together that. A thick copper wire, like copper wire, so it will be very hard, bad bend, 2 lines are there, depending on the use of environmental choice
But multi stranded copper wire is more expensive than single stranded copper wire; there is no hard and fast rule for wire selection in line laying. In our country, the maximum cross-sectional area of single strand copper core is 6 mm2. But in mobile occasions, many strands of soft copper wire must be used so as not to lead to accidents.
