What are the main insulating materials for dry transformers?

In many places of our daily life, we need to use quality assurance dry-type transformers, such as high-rise buildings, airports, docks, lighting and electronic lines in these places are used, and the use of places are generally outdoors, in the face of bad weather or people's damage, the use of dry-type transformers safety has become very important, especially to prevent leakage problems. So what are the main insulating materials of dry transformers? Let's take a look.

First, aromatic polyamide fiber paper

The aromatic polyamide fiber paper in the dry transformer is a kind of high temperature resistant synthetic fiber material, with good physical and mechanical properties, which can make the polymer dielectric stability, and is the main material of wire insulation in the dry transformer. The material should be selected according to the heat resistance level of the dry transformer, and the material that does not match with it can not be used.

Second, dipping paint

For the strong dry transformer brand, there are high requirements for impregnated paint, which requires low viscosity, good dryness, and high moisture resistance and heat resistance. Impregnated paint is mainly used in some windings of impregnated dry transformers to fill gaps and holes between insulation, so as to improve the mechanical properties of the insulation structure, thermal conductivity and other functions.

Three, insulation glue

There is also an insulating adhesive in the dry transformer insulation material, which is mainly used to add fillers when insulating, and the appropriate amount of defoamer can be added to the insulation glue to eliminate the bubbles in the insulation. With the continuous improvement of dry transformer technology, insulation adhesives will also be used in products with higher voltage levels.

Through the introduction, you can learn about some of the main materials of dry transformers, but also let us know more about dry transformers, in the future development, dry transformers will also be developed in many fields, especially large equipment. Dry transformers have high reliability, energy saving and low noise functions, so it also has a protective effect on the environment, with these insulation materials, it can also be safer to use it.
