Different insulation plates correspond to different use relative, separate from play different effects, and the effect of insulating materials like motor is in electrical equipment to separate different parts of the conductor, so that the current can be in accordance with the predetermined direction of activity.

Insulation materials can be divided into gas, liquid and solid if they are in different physical states. Among them, gas insulation materials refer to air, nitrogen, carbon dioxide, sulfur hexafluoride, etc. The liquid insulation material is transformer oil, capacitor oil, cable oil and other mineral oil and silicon oil, triatmosphere biphenyl and other components of oil. Relatively speaking, the classification of solid motor insulation materials is more complex.

Now there are many commonly used motor insulation materials, one is impregnated paint, it can be divided into solvent and solvent free two kinds, the former permeability is better, long storage period, easy to use, but the immersion and drying time is long, slow curing; The latter solidifies quickly, the viscosity changes quickly with temperature, and the mobility, permeability, insulation integrity and so on are very good.

Insulation board

Similarly, the motor insulation material is coating paint, which can not only be used for the coating of the coil and insulating parts after the coating process, but also can be used for motor repair, to strengthen the local insulation ability. Epoxy coating is now more widely used because of its better moisture resistance, mildew resistance, internal dryness and strong film adhesion.

In addition, composite insulation materials are also very common motor insulation materials, including DMD, NMN, NHN, green shell paper, Dupont paper, motor film and other composite insulation materials, this motor insulation material has high heat resistance, small water absorption, soft, high tensile strength, good electrical performance and so on. Can be used for small and medium motor groove insulation, insulation between turns and layers, gasket insulation, transformer insulation and other electrical insulation.

The expected life of transformer is 20140 years. Therefore, the normal operation of the protection transformer and strengthen the reasonable protection of the insulation system, to a large extent, can ensure that the transformer has a relatively long service life, and preventive and predictive protection is the key to improve the service life of the transformer and improve the reliability of power supply. Oil-immersed transformer, the main insulating material is insulating oil and solid insulating material insulating paper, cardboard and wood block c the aging of transformer insulation, is that these materials are affected by environmental factors attack differentiation, decline or loss of insulation strength.
