Why should the transformer be vacuum impregnated with a vacuum impregnator?

Why should the transformer produced by the electronics manufacturer be immersed in paint? What are the effects of dipping paint? Here are some of the aspects that Hui Yue Xiaobian sums up to explain to you.

1 strengthen the insulation. Someof the weak links in the original insulation structure and minorinsulation damage during the process were compensated by dip coating. The insulation performance of the winding is more stable and less affected by the environment.

2 protective effect. Afterthe winding is immersed, a dense enamel film is formed on the outsideof the winding insulation structure, so that moisture, salt spray, moldand dirt in the environment cannot erode the internal insulationstructure.

3 increase mechanical properties. Afterthe winding is immersed, the winding core is formed into a solid whole,which not only reduces the electromagnetic vibration, but also allowsthe winding to bear greater electromagnetic and mechanical forces.

4 is conducive to heat conduction, reducing temperature rise. Afterthe winding is immersed, the air gap in the original insulationstructure is replaced by the cured product of the paint, and the thermalconductivity of Automatic Vacuum Impregnation Machine the paint is much higher than that of the air.

5 has a definite anti-corona effect.
