As the main carrier of power transmission, wire and cable are widely used in electrical equipment, lighting circuits, household appliances, etc. The quality of wire and cable directly affects the quality of the project and the safety of consumers' lives and property. There are many types of wires on the market, and you should use the appropriate wires according to your own electricity load.
Some of the wires sold on the market are cheap, some are more expensive, and some people tend to prefer the cheaper ones first. However, many of the cheap wires often fail to achieve the performance he explained, which may bring them to themselves. Lots of safety hazards. The production technology content of wires is not too high, and the raw materials are not too different. If it is too cheap, it will either cut corners or the quantity is not enough. So how to identify it. Let me tell you a few easier ways to identify:
1. Look at the packaging. The wires of the national standard are often made better, neat, and have a sense of quality when you hold them in your hand.
2. Open the package and take a look at the wires inside. The national standard wire of 1.5--6 square meters requires a skin thickness (insulation thickness) of 0.7mm. If it is too thick, it is non-standard, and the corresponding inner core must be Not enough, you can pull the line skin hard, the ones that are not easy to tear are generally the national standard
3. Burn it with fire, it will be extinguished within 5s after leaving, and the one with certain flame retardant function is the national standard line.
4. Look at the inner core. The higher the brightness of the inner core material (copper), the better the copper, and the luminosity is uniform, shiny, and has no sense of hierarchy. The national standard requires that the inner core must be made of oxygen-free copper. Non-standard ones, such as black rod copper, may have hidden dangers of accidents.
5. The country has certain requirements for the thickness of the inner core, but it is not very strict. But it's not a lot of mistakes, just a little bit, generally invisible errors.
6. For the length, the state does not force the rice to be beaten, but there are many manufacturers who also beat the rice. The rice that is beaten is not necessarily the national standard, but the general national standard generally does not have the rice. Non-standard hit rice is just a means.
7. The state stipulates that there must be a certain mark on the wire. The maximum size will not exceed 500mm, and the next same mark will be printed. Generally, there are product trademarks, manufacturer names, implementation standards, etc.
