What are the shopping requirements for wire and cable?

Wire is now essential for every family, so safety issues must be emphasized. Wire and cable as the main carrier of power transmission, widely used in electrical equipment, lighting lines, household appliances, etc., the quality of its quality directly affects the quality of the project and the consumer's life and property safety. There are many varieties of wires in the market, and it is important to use the right wires according to your electrical load.

Some of the wires sold on the market are cheap and some are more expensive, some people tend to compare the first cheaper, however, cheap wires, there are often a lot of his instructions do not reach that performance, there may be a lot of safety hazards to themselves. Wire production technology is not too high, the raw material is not much difference, if the cheap too much, either cutting corners, or the number is not enough. How to identify it. I give you a few easier to identify the method: 1, look to see the packaging, the national standard wire tend to do better, neat, hand up a sense of quality. 2, to open the package to look at the inside of the wire, the national standard wire 1.5 - 6 square wire requirements is the thickness of the skin (insulation thickness) is 0.7mm, too thick is non-standard, and accordingly, his inner core! Definitely not enough, you can pull the wire skin, not easy to tear is generally the national standard 3, burn with fire, leave the 5s extinguished, there is a certain flame-retardant function for the national standard line. 4, look at the inner core, the inner core of the material (copper) the higher the brightness the better the copper, and the luminosity of the uniformity, luster, no hierarchy. National standard requirements core must be oxygen-free copper. Non-standard, such as black rod copper, there may be potential accidents. 5, the thickness of the core of the state has certain requirements, but not very strict. But will not be wrong a lot, just a very small bit, usually with the eye can not see the error. 6, length, the state is not mandatory to hit the meter, but there are a lot of manufacturers also hit the meter, hit the meter is not necessarily the national standard, but the general national standard is generally not hit the meter. Non-standard meter that is just a means. 7, the state regulations on the wire must be hit with a certain logo, the maximum will not be more than 500mm will have the next same logo hit out, above the general product trademarks, manufacturer's name, the implementation of standards.
