In daily life, we often hear about buying stranded wire. So why should we buy stranded wire? What's the difference? To address this question, let's briefly discuss the specific differences between single-strand and stranded wire, and which is better?
What are the differences between single-strand and stranded wire?
Stranded copper wire is softer and less prone to breaking. It's suitable for applications where the wire must move (such as on distribution boxes and cabinet doors) and where multiple wires are laid together (to facilitate wire laying and bundle formation). Compared to single-strand wire, stranded wire is mostly used for control lines. Due to its structure, single-strand wire is relatively stiffer than stranded wire and is generally used for fixed installations (such as in conduit).
Which is better, single-strand or stranded wire?
1. Stranded wire is softer and easier to bend and route than single-strand wire.
2. Single-strand wire is more sturdy after wiring.
3. Stranded wire is softer and more convenient for daily use (such as multimeter leads).
Single-strand wire has a long service life. Due to its small outer diameter/cross-sectional area ratio, it is less susceptible to oxidation and more resistant to short-circuit current surges. It is generally used in shielded engineering. However, in some areas with strict requirements, such as current transformer secondary leads, the regulations explicitly prohibit the use of BVR wire.
Because of its softer wire, stranded wire is often used in mobile and temporary power supply locations, making it easy to install, drag and drop, and move.
After this brief introduction, I believe everyone has a general understanding of the differences between single-strand and stranded wire. Single-strand copper wire is more convenient than stranded wire for line connections and device wiring. Stranded wire is softer and more convenient for daily use (such as multimeter leads). In daily life, when using wire, choose the right wire according to your needs.
