The more obvious the delamination of the insulating paper, indicating that the quality is unqualified, while the integration is strong, indicating that the quality of such insulating paper is acceptable. Analyze the composition of the sample to improve the quality of its own products. In addition, insulation paper manufacturers can also improve product performances such as elongation, tear resistance strength, and anti-aging functions with reference to parameter requirements. From the analysis of the composition to control the quality of the insulation board, if there are problems such as blooming, and long curing time, the quality of the product can be seen by the consumer through the analysis of the sample components.

DMD insulation paper is a combination of short fiber and chromatography fiber in a water-based slurry, which is then made into a continuous sheet structure by a special paper machine. It is well used in many electrical appliances. Among the dry-type transformers, DMD insulation paper has been recognized by the public for its excellent insulation performance. The following is presented to explain its use in the transformer.

DMD insulation paper has a very low dielectric constant. It has good mechanical strength, not brittle and easy to machine. And there are many varieties of specifications, easy to choose. DMD insulation paper not only has excellent mechanical and electrical performance, but more prominently these indicators are not sensitive to the surrounding humidity and temperature. In addition, DMD insulation paper still has excellent performance at high temperature, low temperature and in the case of large humidity and severe salt spray contamination, which depends on its stable molecular structure and chemical properties.

Two points to be noticed:

Pay attention to the limit value of the electrical insulation paper DMD. DMD paper will be deformed when it’s over 160 degrees, so be sure to pay attention to the use temperature of the electrical insulation paper.

Pay attention to the maintenance of DMD insulation paper. Generally, we will carry out maintenance on electrical and electronic equipment at a fixed time. We can inspect insulation paper, find problems in time, and solve problems.
