How to Check the Number of Pinholes of Enameled Wire?
As an Enameled Copper Wire Manufacturer, share with you.
Enameled wire is currently a very widely used wire in electrical machinery and transformer equipment. There are many factors to judge the quality of enameled wire. The most important one is to look at the continuity of the enameled wire's paint film, that is, to detect the number of pinholes in the enameled wire paint film under a certain length.

The number of pinholes on the paint film can reflect the quality of the enameled wire to a large extent. The fewer the number of pinholes tested, the higher the paint film integrity of the enameled wire and the better the use effect. On the contrary, the quality of the enameled wire will be greatly reduced. . So how do we check the number of pinholes of the enameled wire in practice?
Generally, we will use a professional paint film continuity tester to check the number of pinholes of the enameled wire. This detection mainly uses the principle of high pressure leakage, and the electromagnetic wire and the concave wheel applied with high pressure are carried out by a semi-envelope method. Contact, when it encounters insufficient paint film thickness or serious bare copper defects, the instrument will respond and record the specific number of defects. In this way, you can see the number of pinholes in this section of enameled wire.
Therefore, when we purchase enameled wire, we must also pay attention to checking the number of pinholes of the enameled wire, so as to help us judge the quality of the enameled wire, which is also very useful for our use.
