What issues should be considered when selecting electrical wires for home decoration?
As people pay more and more attention to the quality of home decoration, an increasing number of families choose to buy electrical wires themselves in semi-finished home decoration. But what issues should be noted when making a selection? Taking the BV2.5 square specification as an example (this type of wire is commonly used in households), the national standard (hereinafter referred to as the national standard) specifies a length of 100 meters, a wire diameter of 1.78mm, and the copper material used is purple copper. 1.

As people pay more and more attention to the quality of decoration, more and more families choose to buy their own wires in home decoration semi-packages. But what issues should be noted when choosing?
Taking the BV2.5 square specification as an example (this type of wire is commonly used in households)
The national standard (hereinafter referred to as the national standard) specifies a length of 100 meters, wire diameter: 1.78mm, and the copper material used is purple copper.
1. Length
This is one of the common tricks used to cut corners. Some people may say that the wire I bought has a marked length of 100 meters. You need to be careful; it has a length mark, but in the middle part, some unscrupulous merchants may count 10 meters less. For example, after 30 meters, they start marking it as 40 meters.
2. Wire Diameter
This is one of the most common ways to cut corners in the market.
For example, the 2.5 square BV wire, commonly known as copper single, is a single copper wire. Why is it called 2.5 square? It is because the cross-sectional area of the copper wire in this wire is 2.5 square millimeters.
The diameter of the copper wire in the 2.5 square BV wire is 1.78mm.
3. Quality of Copper Material
Real purple copper has a reddish color, while brass is yellow. Additionally, purple copper is very soft, while brass is hard.
As long as you don't buy copper-clad aluminum (aluminum material, but coated with a layer of copper on the outside, generally used for soft wires), there are currently not too many fakes of yellow brass.
