Wire and cable of some technical points, may you may not understand the electronic wire!

Discriminate the quality of the cable to know these points is enough Now on the market a variety of wire and cable brands, electronic wire and the quality is indeed mixed, but such products once the completion of the device and the use of long-term use, electronic wire and many are to be buried in the device, once the failure is not easy to deal with. In fact, you want to buy a high-quality electronic wire, only need to compare the following aspects. Determine whether there is a certification Now as long as the cable produced by the regular manufacturers are required to go through a variety of views, in addition to the manufacturers of their own testing, but also need to go through the relevant parts of the test, so before you buy the product should also pay attention to whether it has a quality system certification to have standardized certificates of conformity. Together with the network cable packaging are to have the manufacturer's relevant information, inspection chapter, production date, specifications, etc. are not missing. Since the acquisition of wire and other materials, to determine the quality certification is also very important. Comparison of objects is very important After all, we do not see the objects before, especially many projects are in need of high-volume use of wire, so before acquiring must do a good job of the basic comparison of objects. On the one hand, its raw materials need to have a certain degree of softness, and to ensure fatigue strength. Especially on the wire insulator can not have any cracks, need to ensure smooth, and to have a certain thickness. Pay attention to the cross-section of the copper core of the cable, to determine the quality of the cable can be conducive to the subsequent use. Pay attention to the weight of the test Good quality silicone wire used in the quality of the copper core, quality are clearly defined, and to reach a certain weight to ensure its quality. So we still need to pay attention to the measurement of the grain, the general quality of the poorer products in the grain are lacking. We can directly take objects for measurement, so you can determine the specific quality of the wire how, but also to facilitate our comparison of the quality of production. The choice of manufacturers is important Because many projects use more cables, so try to cooperate directly with the rubber-coated wire manufacturers, so that the wholesale acquisition is also guaranteed. The high temperature cables of the formal manufacturers will have a clear product identification, and will also provide good after-sales service. As long as the manufacturer's production capacity is guaranteed, the natural wholesale purchase price is also guaranteed.
