Paper-covered wire is an important part of transformers and other electrical equipment, and its performance requirements are very high. Therefore, after the production of paper-covered wire products, special inspections are generally carried out, and they will not be put into use until they are qualified.
The inspection of the paper covered wire first depends on its size, appearance, and overall performance in accordance with the technical standards of the product and the user's agreement requirements. These need to be judged by inspection. After professional measurement and inspection, and then compared with the technical standards of the product, it meets the requirements and passes. Otherwise, it does not meet the standards.
In addition, through professional inspection, it can also reflect the quality stability of the paper covered wire products and the rationality of the material technology. Therefore, the quality inspection also has the function of checking and identifying. Specifically, in practice, the content of enameled wire inspection mainly includes: appearance, size inspection and measurement, and overall performance inspection. Among them, performance testing includes: mechanical properties, thermal properties, chemical properties, and electrical properties.
After this series of tests, the product quality of the paper covered line is also very guaranteed. When we purchase, we can also distinguish the quality of the product through this series of test reports, so it is very useful. A necessary link.
