Should the wire be single stranded or multiple stranded

First, the difference between single wire and multiple wire
Literally, a single wire is a wire composed of a single thick conductor plus insulation, also known as a hard wire. A multi-strand wire is a wire composed of multiple single thin copper wires, also known as a flexible wire.
Second, is it suitable to use single-strand or multi-strand wires?
1. Construction: multi-strand wire is easy to construct
Because the single-strand wire is made of a thick copper wire, it is a bit harder than the multi-strand wire, so it is more difficult to thread the wire during installation, while the multi-strand wire is easier to thread.
2. Heat dissipation: the heat dissipation of the multi-strand wire has certain advantages
The multi-strand wire is composed of multiple thin copper wires, and there is a certain gap between the copper wire and the copper wire, so it has a certain advantage in heat dissipation.
3. Is it easy to oxidize: single strand is not easy to oxidize
When inspecting a multi-strand wire with a long usage time, you can see that there are many thin copper wire conductors that are oxidized and broken, and the cross-sectional area of ​​the wire is reduced. When the current passes, it will increase the potential safety hazard of electricity; When the strand is oxidized, only a layer on the surface is oxidized, and the conductor inside has no effect.
4. In terms of price: the price of a single strand is relatively cheap
Since the multi-strand wire is made of multiple thin copper wire conductors, the manufacturing process will be more complicated during processing, so the cost will be relatively high. Relatively speaking, the production process of single strand is relatively simple, and the price will be relatively cheap.
After the above analysis, each has its own advantages. If viewed from the point of view, the single strand is more durable, so users prefer to choose this. From the installation point of view, the multi-stranded wire is easier to install, so the installation worker prefers to choose the multi-stranded wire. Impact
