UL electronic wire has the characteristics of acid resistance, oil resistance, moisture resistance, mildew resistance, etc .; excellent insulation mechanicalproperties, bright colors, goodperformance, and safe use. Of course, not only good quality UL electronic wires can meet the above advantages, so how to check the quality of UL electronic wires? Let's listen to what ul electronic wire manufacturers say!

1, the amount of length

The national standard has a clear stipulation on the delivery length of electronic wires and cables. The length of the loop should be 100m and the length of the coil should be greater than 100m. Consumers can measure according to the label length. 0.5%, if it does not reach the lower limit of the standard, it is unqualified. The length of the electronic wire reel is 610m / reel, and each label has a remark. Ul electronic wire manufacturers strictly implement this standard.

2. Observe the smoothness and color of the thread

Electronic wire and cable copper conductors are metal-plated or non-metal-plated annealed copper wires, aluminum conductors are aluminum or aluminum alloy wires, the surface is smooth, copper conductors are lightpurple, and aluminum conductors are silver-white. Other impurities, resulting in a reduction in conductivity.

3.Measure DC resistance TYQ12

In order to ensure that the quality of thepurchased electronic wire is qualified, you can first intercept 3 to 5 meters from theproduct you want to buy to the inspection agency for DC resistance measurement.

4. Detection of insulation and sheathing

The thickness of the insulation and sheath of the electronic wire should be uniform without deflection, and there should be obvious tension and elongation in the hand. At the same time, the surface of the insulation and sheath shall be continuouslyprinted with the manufacturer's name andproduct model, and the interval between the marks: the insulation shall not exceed 200mm, and the sheath shall not exceed 500mm.

Of course, in order to make life more convenient and electronic wires to be our assistants, then we not only need to understand some knowledge of electronic wireprocessing, but also learn to identify and see the advantages and disadvantages. Only when there is no room for inferiorproducts can high-qualityproducts stand out. For the better quality of our lives, we choose high-quality electronic wires to serve our lives.

Appeals are four simple methods to identify the quality of UL electronic wires. UL electronic wiresproduced by ul electronic wire manufacturers are mainly used in connection cables for household appliances, lighting fixtures, electronic equipment, instruments, electronic toys, and security equipment. Hope this article can help everyone.
