flexible laminates is one of the key factors to determine the technical and economic indicators of motor and electrical appliances. One of the important technical and economic indicators of the motor is the mass power ratio, that is, the kg / kw value. Reduce the ratio, the motor has important significance. It is reported that from 1900 to 1967, 1hp (0.75kW) motor quality from 40kg to 10kg, has now been reduced to 6kg / kW level. An important reason for this change is the use of insulating materials with high heat resistance. Reduce the kg / kW value can save a lot of metal materials, reduce motor costs.
Such as a A-class (105 ℃) motor with H-class (180 ℃) insulation, can reduce the volume of 30% to 50%, saving copper 20%, silicon steel sheet 30% to 50%, cast iron 25%. Of course, using the same model machine, with a higher temperature index insulation material, can improve the power or extend the life of the motor. From the electrical, electrical products, the cost of the situation, the cost of insulating materials in about half of these are the insulating materials in the electrical, electrical industry, the status and role.

Product structure and performance of DMD insulating paper

DMD insulation paper has good mechanical strength, dielectric properties and high heat resistance (B and F), is Y series motor stereotypes insulation material, can be used as small and medium-sized motor slot insulation, turn Insulation, liner insulation and transformer insulation. Part of the thickness of the product has been widely sold to Europe and the United States and Southeast Asia market.

Main features of insulating materials

Electrical technology Insulation material is usually referred to as the resistance coefficient greater than 10 9 square Ω.cm material. The role of insulating material is mainly in the electrical equipment to separate the potential of the live part of the isolation.
So the NMN Insulating material to have a good dielectric properties, that is, have a high insulation resistance and pressure strength, to be able to avoid leakage, creep and breakdown and other accidents; followed by insulation materials, heat resistance is better, mainly to To ensure that there will be no long-term heat due to performance changes; in addition to good thermal conductivity, moisture and a higher mechanical strength and process processing and so on.
Electrician commonly used flexible composite materials, according to the different chemical properties, can be divided into inorganic materials, organic. Insulation materials and mixed insulation materials three types.
