How to recognize between fake and Original Wire & Cable

Wire & Cable

It is possible that it will be difficult for you to distinguish the original wire and cable from the fake one. In this article, we intend to introduce you to some safe methods so that you don't have to worry anymore when buying your wire and cable . Because if you don't recognise  it will cause harmful damages and will be costly.


1-to produce wire and cable , we use Copper as a conductor of Electricity. You Can find out the presence of copper by cutting the cross section of the wire. of course , sometimes manufacturers use other compounds such as Aluminium for for electric cables in order to lower the price of the product to some extent.

2-In high-quality cables, the wire insulation will always be easily separated from the conductor

3-After cutting the cross-section of the wire, you should be able to see the copper current conductor in the center. The lack of centrality of the conductor in the wire will cause the strands to protrude, causing tears in the insulation and coating. Also, over time as the current passes and the conductor heats up, it will damage the conductor.

4-After cutting the cross-section of the cable, the diameter of the insulation around the conductor should be the same. Otherwise, you are buying a poor-quality power cable

5-The large diameter of the cable sheath and wire insulation is not a proof of high quality. Low weight of the conductor with thick coating is a tell-tale sign that the wire is of poor quality. This will also make it difficult for ordinary customers to distinguish between a genuine cable and a fake one. However, with a smooth cross-section cut, you can compare the ratio of the conductor with that of the insulation and coating. The coating should not be disproportionately thicker than the conductor. If so, you are probably looking at a poor-quality wire.

6-When exposed to moisture, most conductors will oxidise. If copper and aluminum, which are among the important metals in the construction of wire conductors and all kinds of cables, are oxidised, they will change colour to black and will have a rough and matte surface. With this method, it will be easier to recognise between genuine and fake wires and cables.

7-Another way to distinguish original wire and cable from fake is to observe the surface of the wire and cable. The appearance of wire and cable should be smooth and without protrusions or depressions. This method can be detected visually or by touching the wire and cable surface.

8-Bonded connections in the conductor cause a significant increase in heat and melting of the insulation, as well as an increase in point resistance. These connections, in the insulation of the cable strands, will cause a decrease in the insulation resistance and the occurrence of a connection or fire. Another reason for the presence of protrusions or depressions that appear on the surface of wires and cables is the presence of joint connections.

9-Poor-quality insulation and coating have little durability. For this reason, as a result of any mechanical stress during cabling or other situations, these insulations will be torn in most cases, which can cause electric shock, short circuit, and even fire.

10-The most common type of insulation in wire and cable is PVC. To distinguish between genuine and fake wires and cables and whether PVC insulation is used in these wires or cables, you should pay attention to the fact that the insulation and coating in non-standard wires and cables will be easily removed by your hand And even a part of it can be scratched and separated with a nail. If this happens, it means that the insulation and coating of the wire and cable is not An original pVC and may be its recycled plastic .

11-The most common metal in the wire and cable industry is copper. For this reason, the copper conductor must be softened or annealed from pure copper (99.9%). Also, the copper surface should be shiny, and the copper strands should be flexible and not be black (not oxidised).

other Methods of recognising Genuine and Fake wire and cables

-Use of CCA(copper Clad Aluminium) instead of copper. If CCA is used, the cores of the conductors are white and they are flameble with fire of a lighter .

-Use of copper in wires and cables  less than the permissible limit.

-The length of the wire is less than the length stated on the product label
