Introduction of Insulating Property Of Crepe Paper Tubes
Insulation materials should first have high insulation resistance and compressive strength, and can avoid leakage, breakdown and other accidents. Second, the heat resistance is better, avoid aging and deterioration due to long-term overheating, in addition, there should be good thermal conductivity, moisture-proof resistance and high mechanical strength and easy processing and other characteristics. According to the above requirements, the properties of insulating materials are insulation strength, tensile strength, specific gravity, expansion coefficient and so on.
The insulating materials commonly used by electricians can be divided into inorganic insulating materials, organic insulating materials and mixed insulating materials according to their different chemical properties. Commonly used inorganic insulating materials are: mica, asbestos, marble, porcelain, glass, sulphur yellow, etc., mainly used as motor, electrical winding insulation, switch backplane and insulators.
