The same is insulating paper, but it can be divided into different types such as DMDM ​​insulating paper, DMD insulating paper and NHN insulating paper.

DMD insulating paper is a soft material of polyester film polyester fiber non-woven fabric. The soft composite material is composed of a polyester film layer coated with an adhesive and a polyester non-woven fabric, which is made by composite calendering. The most obvious difference between DMD insulating paper and DMDM ​​insulating paper is the number of layers. DMD refers to a three-layer composite insulating paper, and DMDM ​​is a composite insulating paper. Although the number of layers is different, they have good electromechanical properties and are suitable for motor slot insulation and gasket insulation, with a heat resistance level of 130.

NHN insulating paper, it is an edge material that must be used as an electrical equipment such as cables and coils, so it has good insulation and mechanical strength. We can observe and judge NHN insulating paper intuitively, such as product description, insulation resistance, leakage current and other characteristic parameters of insulation leakage. When the moisture content of the insulating paper is high, its conductivity will increase, resulting in an increase in the leakage current value, so be sure to choose high-quality products. This can greatly improve the transformer design, reduce electrical losses, improve standby capacity, improve safety and reliability, and reduce wires and steel cores, reducing costs.

Insulating paper is widely used in wedge-shaped insulation and mutual insulation edges and end laminates of motors and generators, protecting various equipment and enabling various rotating equipment to separate better thermal performance, better mechanical properties, higher safety, and longer service life.
