In terms of structure, NMN composite insulation paper adopts a three-layer structure, and the outer two layers are NOMEX insulation paper, and the inner layer is MYLAR polyester film. It is precisely because of this that NMN composite insulation paper not only has the excellent thermal resistance performance of NOMEX, but also has excellent dielectric strength and mechanical properties of polyester film.
Excellent performance makes NMN composite insulation paper suitable for many occasions, among which the more common is the inter-turn insulation and gasket insulation for F-class and H-class motors, and the various parts of the motor are effectively protected.
The inner diameter of NMN composite insulation paper is 3 inches, which can be supplied in rolls or cut into strips or sheets. Generally, the weight of each roll of NMN composite insulation paper is 60-70KG; the length depends mainly on the customer’s needs. The different requirements of width can range from 3.5mm to 914mm.
In order to maintain good performance of NMN composite insulation paper, NMN composite insulation paper should be stored in a dry and clean warehouse below 0°C, and it must not be close to the fire source, nor can it be exposed to heat or direct sunlight to avoid being damaged, reducing its performance and shortening its service life.
The fiber material of NMN composite insulation paper is the basic solid tissue component of the plant, so that in the atoms of its constituent material molecules, there are positively charged nuclei and negatively charged electrons that operate around the nuclei. Unlike metal conductors, very small electrical currents in the insulators come mainly from ion conductance.
This fiber in NMN composite insulating paper is not only easy to absorb moisture, but also weakens the interaction between hydroxyl radicals when the paper fiber absorbs water, and the mechanical strength deteriorates rapidly under unstable fiber structure. Therefore, NMN composite insulation paper parts are generally used after drying or vacuum drying and oil immersion or insulating lacquer.
