Insulation Materials Heat Is Better
The main function of the insulating material is to isolate the conductors of different parts in the electrical equipment so that the current can flow in the predetermined direction. Insulation Materials Insulation material is the weakest link in electrical equipment, many failures occur in the insulation part, so the insulation material should have good dielectric properties, high insulation resistance and compressive strength; heat resistance is good, and will not be due to long-term heat Causing changes in performance; good moisture, lightning, mildew and high mechanical strength, and easy processing.
Insulation material in the long-term use, Insulation Materials in temperature, electrical, mechanical and other aspects of the role of insulation performance will gradually deteriorate, known as the insulation aging. The temperature has great influence on the service life of the insulating material and the aging of the insulation. Therefore, Insulation Materials in order to ensure the long-term safe operation of the electrical equipment, the heat-resistant grade and the ultimate working temperature of the insulating material are clearly defined. If the operating temperature of the electrical equipment exceeds the ultimate operating temperature of the insulation material used, the service life of the insulating material is shortened. Generally more than 6 ℃, the life of insulating materials will be shortened by about half.
Electrician commonly used insulating material according to its physical state is different, can be divided into gas, liquid, solid three categories. Gas insulating materials such as air, nitrogen, Insulation Materials carbon dioxide, sulfur hexafluoride and the like; liquid insulating materials such as transformer oil, capacitor oil, cable oil and other mineral oil and silicone oil, three atmosphere of benzene and other synthetic oil; solid insulation materials according to its application or process Different characteristics, Insulation Materials but also can be divided into six categories. In order to fully reflect the type of solid insulation materials, varieties and heat-resistant grades, solid insulation materials using four digits to represent its model. There are many different varieties in the same material, such as the first type of material, 0 for the leaching paint, 2 for the paint, 3 for the enamel, 4 for the viscose and resin, 6 for the silicon steel, If the second type of material, 0,1,2 said cotton fiber paint cloth, 4,5 said glass fiber paint cloth, 6 said the semiconductor paint cloth and adhesive tape, 7 said paint tube, 8 said film, 9 said Film products. For example, 1031 for the J-based phenolic alkyd paint, is B-class; 1032 for the three dihydrogenamine jelly paint, is B-class.
Due to the more types of mica, in addition to mica outside the other mica products but also in the back of the four digits plus a digit, Insulation Materials 1 said powder mica products, 2 said phlogopite products. For example, 5438 a 1 for the epoxy glass powder mica tape, 5450 a 2 for the silicone glass mica tape.
Insulation laminates, also known as laminated products (laminated boards, rods, tubes, etc.) or laminated plastic. Insulating laminates are insulating materials made of organic fibers or inorganic fibers, Insulation Materials cloth as substrates, dipped in different adhesives, and hot pressed (or rolled).
Using different substrates, the amount of dry agent, molding process, can be made into different heat levels, different mechanical, electrical, physical and chemical properties of the products. Electric motors and other electrical equipment used in the laminated products, mainly for insulation structures, Insulation Materials such as winding bracket, pad, pad, groove wedge and so on.
