  • HOW TO DETERMINE THE QUALITY OF THE CABLE?

    Unfortunately, some of the suppliers of cable products do not always adhere to quality standards. The main “trick” is a reduction in the cross section of the conductor. And sometimes significantly. We encountered cable samples with a marking of a cross-section of 1.5 mm2, while the actual cross section was 0.8 mm2. Of course, it’s difficult to check the section at the point of purchase: Imagine that you measure each wire in the store with a micrometer and then do the calculations. We will teach you how to do a cable quality test.

    What should you pay attention when inspecting the cable

    You can meet the cable from aluminum, coated with copper (sold as copper cable and has the necessary marking). Such a cable is easy to check: a cut of the conductor on the cable glows in white – aluminum.

    Some manufacturers use low-quality copper or aluminum to reduce costs. In such cables, the service life and conductance of the core is much lower than that established by the quality standard. Check the quality of the metal conductive as follows:

    Your actions, cable test execution

    Try several times to bend and straighten the cable, aluminum should withstand at least 7-8 bends, and copper – 30-40;
    the cable from high-quality copper or aluminum should be easily bent and not springy;
    A copper or aluminum conductor on a cable that has just been stripped must have a bright (glare) color.
    If the core is heterogeneous in color and has dark spots, this is not electrical copper (aluminum).
