Commonly used single-core wires and multi-core wires are basically copper core wires, good conductivity, low resistance, good electrical performance, and more stable and reliable when used. The structure of single-core and multi-core is not the same, so which single-core wire and multi-core wire is better?

1 Construction aspect

Multi-strand wire construction is more convenient, because single-strand wire is made of thick copper wire, so it is harder than multi-strand wire. Therefore, it is more difficult to thread during construction, and multi-strand wires are much easier to thread.

2 Heat dissipation

The multi-strand wire has certain advantages in heat dissipation, and the multi-strand wire is composed of many thin copper wires, and there is a certain gap between the copper wire and the copper wire, so it has certain advantages in heat dissipation.

3 Price aspect

The price of a single strand is relatively cheap, and the multi-strand strand is composed of many thin copper wires. In the process of production and processing, the process is slightly more complicated, so the cost will be a little higher, and the price of a single strand is relatively cheaper. Based on the comparison of the above three factors, it is better to choose multi-core wires than single-core wires.

Buy RV wire precautions

1. Look at the packaging mark: whether the information on the certificate is complete, there is "CCC" certification and quality system certification.

2. Look at the manufacturing process: a good wire is not biased, and a section of copper wire is cut off to see whether its core is located in the middle of the insulation layer.

3. Look at the quality of the copper core: the copper core is purplish red and shiny, while the inferior one is yellow or white.

4. Look at the size: See whether the length of the wire and the cross-sectional area of the inner core are consistent with the mark to avoid shortfalls.
