It's true, it's true, it's true, it's true. Now the non-standard and national standard wire and cable on the market is really dazzling, some of the production of non-standard wire packaging is even more professional than the national standard, it is difficult to distinguish between true and false, then how to distinguish the true and false national standard wire, today Xiaobian will share one or two, I hope to help you buyers.

First, look at product series certification

See whether there is a quality system certificate; See whether the certificate is standard; See whether there is a factory name, factory address, inspection seal, production date; See if the wire is printed with trademarks, specifications, voltage, etc. All the regular manufacturers of a series of certificates are available, if there is no detailed quality certification, the procurement enterprise can carefully examine.


Second, weigh the length

Good quality wire? Generally within the specified weight range.
Third, look at the copper

The higher the copper brightness, the better the copper quality, and the brightness is uniform, shiny, and there is no layer. The qualified copper core wire copper core should be purplish red, shiny and soft. If you can cut off a small piece of plastic skin, carefully check the copper wire inside, touch the top of the copper wire with the palm of your hand, it should feel flat and no tingling, feel more soft, and shoddy copper core copper core is purplish black, yellow or white, many impurities, poor mechanical strength, poor toughness, a little force will break, and the wire is often broken. Click here to learn more cable technology Check, you just peel one end of the wire 2CM, and then use a piece of white paper on the copper core slightly rub, if there is black material on the white paper, it means that there are more impurities in the copper core. In addition, the insulation layer of shoddy wire seems to be very thick, in fact, most of them are made of recycled plastic, and over time, the insulation layer will age and leak electricity.

4. Try it by hand

Can a wire head be bent repeatedly by hand? Any soft feel, good fatigue strength, plastic or rubber feel elastic and no cracks on the wire insulator is excellent products. At the same time, due to the low production cost of fake and shoddy wires? Therefore? Is there a difference in the feel? Often sold under the guise of cheap quality? Makes it hard to tell the real from the fake.

5. Check the sheath

The insulation of fake products looks thick? But it's actually mostly made from recycled material, you know? Product toughness is poor, damage resistance is poor, easy to peel and crack? Especially in the home improvement process? Very easy to wear out? There are huge security risks. Generally, insulation sheathing processed with recycled materials as long as there are no metal impurities in the material? Can you pass a high-voltage test? But ordinary consumers can distinguish the good or bad of the sheath through a simple stretching method. Insulation sheath for reprocessing? Mostly mixed with calcium carbonate? In the process of stretching will appear white, easy to break the phenomenon.

6. Use fire

Inferior wire and cable will burn quickly with fire, there is an open flame and smoke; The good quality cable burns slowly, has a small amount of smoke or smoke-free, and has no open flame.
