Dmd Material Insulation Paper is made up of two layers of polyester non-woven fabric sandwiched between a layer of insulating polyester film composite of the three layer of insulation material. DMD is divided into B class and F class two, B class temperature resistance 105 degrees, F class temperature resistance of 155 degrees. DMD products in the appearance of the appearance of smooth, no bubbles, creases are preferred. DMD paper is used in slot insulation and insulation for motor.
It has excellent electrical insulation properties. The structure of the DMD ensures that it provides good electrical strength. The specific breakdown voltage rating varies according to the total thickness.
It also has good mechanical strength. In addition to its rugged electrical properties, DMD is a strong and flexible insulating paper material. It can withstand temperatures up to 155 ° C (Class F), and after 10 minutes of testing at this temperature, layer delamination does not occur.
In addition to excellent strength, Dmd Material Insulation Paper is also very easy to use. The nonwoven fabric layers on both sides of the polyester film are sealed with a varnish coating. This ensures that the material has a smooth surface finish and will not be captured if a machine taping system is applied.
Dmd Material Insulation Paper is commonly used in low and medium voltage motors. Specific applications include: slot liners for electrical motors, insulation; interlayer insulation materials for transformers, etc.
