Enameled wire is widely used in electronic products. Most of the manufacturing materials of cables and wires are also enameled wires. Enameled wires have a significant effect on transmitting electricity. The market scope of enameled wire is constantly expanding, and the manufacturing technology of enameled wire has also been greatly improved, and its production efficiency has been accelerated a lot. When we buy enameled wire, there is still a lot of space to choose, because there is no better specification in the enameled wire market, so we need to know the relevant methods to identify the quality when buying enameled wire, let's take a look at it together.
1. Look carefully at the printing sample of the trademark, the handwriting is blurred and the address is unknown. It means to look at the printed words on the label and the insulating cover. If there are typos or different printing shades, or the words are blurred, pay attention.
2. Twist and rub the insulating skin by hand, and the quality of the color and characters will fade. It refers to rubbing the insulating sheath with fingers. Some inferior enameled wire sheaths are easy to fade. After rubbing, the color of the sheath or the words printed on the sheath are wiped off. Generally, inferior enameled wires are inferior.
3. Use your fingernails to scratch and pinch the enameled wire. It refers to scratching and pinching the insulating sheath with a fingernail. The one that can be scratched and pinched is generally inferior enameled wire.
4. Bend the enameled wire repeatedly, and it will break three to four times. Refers to repeatedly bending the enameled wire. The insulation layer of the inferior enameled wire is generally of poor material. After bending 3 to 4 times, the insulating layer will break.
5. Light the enameled wire with fire. It means that the insulating layer is ignited, and it is inferior enameled wire that can spontaneously ignite after leaving the open flame.
6. The color becomes darker and the gloss is lighter. Refers to the color of the wire core, the color of the inferior enameled wire is dark and has no metallic luster.
It is relatively simple to distinguish between inferior enameled wire and good quality enameled wire. There will be many defects in the appearance of inferior enameled wire, and the workmanship is not fine enough. If you want to more accurately identify the quality when buying, then you can refer to the above suggestions, I believe it can help you avoid buying inferior enameled wires. Inferior enameled wire is not only hindered in its function, but the use of inferior enameled wire may lead to larger accidents. Therefore, regulating the enameled wire market is an urgent matter that needs to be done now, which can help the enameled wire industry go further.
