Brief analysis: the key points of wire and cable purchase

There are many types of wires in the market, and you should use the right wire according to your own power load.  Some of the wires sold on the market are cheap and some are more expensive, and some people tend to be cheaper first, but cheap wires, often many of which do not reach the performance he explained, may bring a lot of safety hazards to themselves.

 The production technology content of wires is not too high, and the raw materials are not much different, if they are too cheap, they will either cut corners or the quantity is not enough. So how to identify. I will tell you a few methods that are easier to identify:

 First, look at the packaging, the national standard wires are often better, neat, and have a sense of quality when held in hand.  

Second, to open the package to see the wires inside, the national standard wire 1.5 ~ 6 square wire requirements is skin thickness (insulation thickness) is 0.7mm, too thick is non-standard, the corresponding his inner core is definitely not enough, wire skin you can pull hard, not easy to tear is generally the national standard.  

Third, burn it with fire, and extinguish it within 5s after leaving, and have a certain flame retardant function for the national standard line. 

 Fourth, look at the inner core, the higher the brightness of the material (copper) of the inner core, the better the copper quality, and the luminosity is uniform, glossy, and there is no sense of layering. The national standard requires that the inner core must use oxygen-free copper. Non-standard such as black rod copper may have potential accident hazards. 

 Fifth, the thickness of the core country has certain requirements, but it is not very strict. But there will be no mistake, just a small little, generally not visible with the eye.  

Sixth, the length, the state does not force to hit rice, but many manufacturers also hit rice, hit rice is not necessarily the national standard, but the general national standard generally does not hit rice. Non-standard rice is just a means. 　　  

Seven, the state stipulates that there must be a certain logo on the wire, the maximum will not exceed 500mm will have the next identical logo punched out, which generally has the product's trademark, manufacturer name, implementation standards, etc.
