Chinese cable brands analyze common quality issues of wires and cables for you


Once there is a problem with the cable, it can be very difficult to identify the cause, and dealing with it requires a lot of work, which can have a significant impact on its use. Therefore, conducting various analyses of cables to prevent problems from occurring is crucial for the safe operation of the wire and cable system.

There are generally two main reasons for cable problems, one is the use of inferior cables, and the other is due to improper use or maintenance of the cables.

Chinese cable brands

Chinese cable brands tell you that common quality issues in cables include:

      1.If the structure is unqualified, the thinnest point of the insulation layer thickness is lower than the minimum value specified in the standard, or the average thickness is lower than the nominal value, there is a risk of breakdown during use.

   2.The cross-linking degree is unqualified, the cross-linking degree does not meet the standard, the heat resistance performance of the cable is unqualified, and it cannot meet the requirements of working temperature, let alone the temperature allowed by short circuit, so the electrical performance is greatly reduced.

   3.The thickness of the cable is uneven, and due to the different cross-sections of each section of the cable during use, the heating of the cable is uneven, which can affect the lifespan of the insulation.


      Chinese cable brand manufacturers remind you that if you want to avoid these problems, the most important thing is to use qualified cables.
