(1) and inferior appearance and authenticity of the twisted pair twisted pair has no obvious difference, only the rubber on the font slightly smaller, the same number character more than 1 cm, less total length after we need to use the sample for easy identification.
2. The genuine twisted-pair wire core insulation material has bright color and obvious reflection, and the white wire is transparent with copper color;
The insulating material of fake and inferior twisted pair is white, which can't be seen in the light and natural light, and is opaque, especially light green.
3. The insulation material of fake and inferior twisted-pair wire is not tightly wrapped with the copper core. Just hold the end of the wire and shake it a few times, you can see the copper core is above the notch of the insulation layer;
In the same situation, the authentic product can always keep the incision level.
4. The toughness of the insulation material of the fake twisted-pair wire is poor. If you pinch the insulator with your right thumb and forefinger nails, you can easily pull off a section of the insulation layer by applying force on both sides, but not on the genuine twisted-pair wire.
5. The copper core of fake and inferior twisted-pair wire is thinner than the genuine copper core, which can be detected on the hand feel, but also with the help of samples.
It seems that the counterfeiter in order to be able to mix pearls, on the appearance is very hard, but in order to control the cost to obtain more benefits, the internal often use material is insufficient, so when buying twisted pair line, it is best to cut a section to open for inspection
