Wholesale 6641 F-DMD Motor Electrical Insulation Paper

6641 DMD-F insulating material is a solid insulating material made of 6020/6021 transparent or milky white polyester film compounded with electrical non-woven fabric on both sides. Its characteristics are chemical resistance, high temperature resistance, glossy, partially transparent or translucent, light weight and strong. Due to the higher density of solid insulating materials, the breakdown strength is also much higher, and the insulation resistance, dielectric constant and sum of solid insulating materials vary widely. We supply a variety of solid insulation materials for motors, which can isolate different electrical conductors and have a supporting role at the same time.

6641 DMD-F Insulating Paper Material Properties:

1. Chemical resistance

2. Good mechanical and electrical properties, temperature class F (155℃).

3. Most of them are good insulators

4. Lightweight and sturdy

5. Glossy, partially transparent or translucent

6. Wide range of uses, many functions, easy to color, and some high temperature resistance

7. Storing goods can play a moisture-proof effect.

8. It is easy to process and can be mass-produced, and the price is cheap

6641 DMD-F Application Areas:

6641 DMD-F Insulation Material is used in low-voltage motors, power tools, electrical appliances as slot insulation, gasket insulation, inter-turn insulation and slot wedge insulation and interlayer insulation of transformers.

We offer a wide range of solid electrical insulation materials, mainly divided into two categories: inorganic and organic.

Inorganic solid insulating materials: mainly include powder mica and mica products, glass, glass fiber and its products, as well as electric porcelain, alumina film, etc. They are resistant to high temperature, not easy to age, and have considerable mechanical strength. Some of these materials, such as etc., have low cost and occupy a certain position in the application. The process of glass is simpler than that of ceramics and can be used to manufacture. Glass fiber can be made into silk, cloth and tape, which has much higher heat resistance than organic fiber, and plays an important role in the development of insulation structure to high temperature.

Organic solid insulating materials: mainly natural materials, such as paper, cotton, silk, curable vegetable oil, etc. These materials are flexible, can meet the application process requirements, and are easy to obtain. Silicone resin combined with low-alkali glass cloth greatly improves the heat resistance level of. Polyethylene formal opens up broad prospects for enameled wire made of lacquer base, replacing silk-covered wire and yarn-covered wire. The thickness of polyester film is only tens of microns. Using it to replace the original paper and cloth greatly improves the technical and economic indicators of motors and electrical appliances. Polyaramid fiber paper and polyester film and polyimide film are used together to make the heat resistance of motor slot insulation into F and H respectively. There are similar developments in elastomeric materials, such as heat-resistant silicone rubber, oil-resistant nitrile rubber, and subsequently fluororubber, ethylene-propylene rubber, and the like.
