Introduction to the Three Kinds of Insulated Paper in Transformers

We know that transformers are a device specifically designed to change AC voltages and may be hazardous to conduct electricity during long-term operation, so we also need to use insulation materials, such as insulation paper, during use. However, choosing such a product is not so simple. Let’s look at the three types of transformer insulated paper commonly used in transformers.
1, The first of three insulated paper commonly used in transformers:
Transformer with kraft paper, the color is yellow, thickness between 0.13 mm and 0.5 mm.
Kraft insulation paper
2, The second of the three commonly used insulated paper in transformers:
NOMEX insulation paper. Also known as Nome paper, it is light yellow and has a thickness between 0.05 mm and 0.76 mm.
Nomex insulation paper
3, The third of three commonly used insulated paper in transformers:
NMN insulation paper. Depth: 0.1-0.5 mm.
NMN Insulation Paper
The color and thickness of three types of transformer insulation paper commonly used in transformers, such as kraft paper for transformers, NOMEX insulation paper and NMN insulation paper are described above. Because insulation materials of different thicknesses have different insulation effects, different types of insulation paper also have different insulation effects. I hope the above will help you choose the right transformer paper.
