How To Distinguish between National Standard Wires And Non-standard Wires

Wires and cables are necessary and irreplaceable equipment for each of our households. We all know that to buy wires, you must buy high-quality wires. Through neighbors and experienced people in the streets and alleys, we know that the Chinese standard wires in the wire field are quality comparisons. High, because the wires are produced according to the standards controlled by the state, so how do we distinguish between national standard wires and non-national standard wires when buying wires? First of all, we have to figure out what is a national standard wire and what is a non-national standard wire.

What are national standard wires and non-standard wires

The so-called national standard wire refers to the wire produced according to the standard technology promulgated by the state, which is collectively referred to as the national standard wire. If it is not a national standard wire, it is produced by those informal manufacturers to meet market demand. This wire has some differences in appearance and conductors.

How to see whether the wire is the national standard

1. First of all, we can look at the surface and appearance of the wire. If it is a regular national standard wire, the wire surface is affixed with a national certificate of conformity, and there are other quality system certificates, such as "3C" certification and ISO9001 quality system certification logo, etc. wait. And a clear address of the manufacturer, including inspection stamps, qualified QC inspectors, and production dates. In addition, different brands of national standard wires will have different trademarks plus the specifications, volume and area of the national standard wires, etc. At the same time, carefully observe whether the appearance color of the national standard wire is bright and whether the color is soft. Based on these, you can judge whether it is a regular national standard wire, because the production technology requirements of the regular national standard wire are relatively high, and ordinary small workshops cannot make it.

2. Bend and fold the wire a few times with your hands to see if there are any cracks on the surface. If the wire feels soft, how fast will it return to its original shape? If the feel is good and the recovery is fast, it means that it is a national standard wire with better quality.

3. If it is a national standard wire, the weight of 100 meters of 1.5 square aluminum core wire is generally about 1.8 kg. The 4 square copper core wire weighs about 4.4 kg per 100 meters. If it is not the national standard line, the difference in weight of the wire will be relatively large, because it is not a real pure copper conductor, there will be a lot of impurities, resulting in a slightly slower conduction speed of such a wire.

4. There is also the price of wires. The national standard wires are clearly marked, because the production process of national standard wires is complicated, and the price is also slightly expensive. If it is a non-national standard wire, its production cost is relatively low, consumers must not buy cheap wires when buying, because it is not a national standard wire, it is also safe to use, and it is easy to leak electricity, which may cause life danger to people
