Judging the quality of cables is enough to know these points. Nowadays, there are various brands of wires and cables on the market, and the quality of electronic wires is indeed mixed. However, once such products are installed and used, they are used for a long time. Electronic wires and many of them need to be buried in devices, and once a malfunction occurs, it is indeed difficult to handle. In fact, if you want to purchase high-quality electronic cables, you only need to compare them from the following aspects. To determine whether there is certification, all cables produced by legitimate manufacturers need to undergo multiple inspections. In addition to self inspection by the manufacturer, they also need to undergo relevant testing. Therefore, before purchasing a product, it is also necessary to pay attention to whether it has a quality system certification and has a standardized certificate of conformity.

The packaging of the network cable must have relevant information from the manufacturer, including inspection stamps, production dates, specifications, etc. It is also crucial to ensure quality certification when purchasing materials such as wires. Comparing items is crucial, after all, before we see them, especially many projects that require large-scale use of wires, so it is necessary to do a basic comparison of items before purchasing. On the one hand, its raw material needs to have a certain degree of softness and ensure fatigue resistance. Especially, there should be no cracks on the insulation of the wires, and it is necessary to ensure smoothness and a certain thickness. It is important to pay attention to the cross-sectional area of the copper core of the cable and determine its quality in order to facilitate subsequent use.

Pay attention to the weight detection. The quality and quality of the copper core used in high-quality silicone wire are clearly specified, and must reach a certain weight to ensure its quality. So we still need to pay attention to the measurement of COFCO. Generally, poor quality products are lacking in COFCO. We can directly take something for measurement, which can determine the specific quality of the wire and facilitate our comparison of production quality. The selection of manufacturers is very important because many projects use a large number of cables, so it is recommended to directly cooperate with the manufacturers of rubber wrapped wires, so that wholesale procurement is also guaranteed. Regular manufacturers of high-temperature cables will have clear product identification and provide good after-sales service. As long as the manufacturer's production capacity is guaranteed, the natural wholesale purchase price is also guaranteed.
