Product Description:

 1. Introduction:

Mica tube is made of mica paper with highperformance organic silicon resin. After heating and pressing, the mica plate can be made into rigid or flexible insulating plates. The mica content is about 90% and the organic silicon resin content is 10%.

2. Main features of Mica Parts:

Rigid mica tubes are featured with high strength, good performance, less smoke, less odor etc. 

3. Applications:

This series mica plates are used mainly in household appliances (toaster ovens, microwave ovens, warm air blowers, hair dryers, electric iron etc.), metallurgy (such as linefrequency furnaces, medium frequency furnaces, electric arc furnace, etc.), medical equipment and other industries, used as the heating support, lining plate and partition plate of the electric appliances described above.

Q:What type of enameled wire and insulation material is used for the compressor
Motor insulation class The insulation class is divided according to the permissible limit temperature of the insulation material used for the motor. There are Y, A, E, B, F, H, C and several other levels, the allowable limit temperature at all levels as shown in the table below. The so-called permissible limit temperature refers to the permissible maximum operating temperature of the motor insulation material, which reflects the heat resistance of the insulating material. Insulation material is divided into Y grade, A grade, grade E, grade B, grade F, grade H, grade C, permissible temperature (℃) 90,105,120,130,155,180, 180 ℃ or higher.
Q:What is the insulating material in the middle of the connecting wire?
The original wire is insulated paint, you often use, you can also use quick-drying insulating paint.
Q:What insulating material is best `?
According to their polarity is divided into weak polarity, non-polarity, polarity and strong polarity 4. According to the material source is divided into mineral insulating oil, synthetic insulating oil and vegetable oil 3. Mineral insulating oil referred to as mineral oil, The relative dielectric constant is about 2.2, and the breakdown voltage in the standard electrode is 35 to 50 kV (kV). The flash point is 125 to 135 ° C for the manufacture of transformers and cables , Capacitors, etc. Synthetic insulating oil is a synthetic liquid insulating material.As the mineral oil is a mixture of various hydrocarbons, it is difficult to remove the components of the insulation performance, and the preparation process is complex, easy to burn, low heat resistance , The dielectric constant is not high, so the research and development of the excellent performance of the synthetic insulating oil. Now have used aromatic synthetic oil, silicone oil, ester oil, ether and sulfone synthetic oil, polybutylene, etc. Vegetable oil use Castor oil, soybean oil, rapeseed oil, etc. Castor oil is an excellent dip capacitor for pulse capacitors
Q:Brass is not an insulating material?
Brass is not insulating material. On the contrary is the brass is conductive material. Brass texture hard, can not bend. No copper flexibility is good, so brass can only do a fixed copper conductive use.
Q:Wear-resistant, high temperature, insulation materials which
Polytetrafluoroethylene (engineering plastics) - (- 195 ~ 250) ℃ can be used for a long time. For corrosion-resistant parts, anti-friction wear parts, seals, insulation and so on. Silicone rubber - Upper temperature limit (100 to 300) ° C. For high and low temperature parts, insulation, pipe joints and so on. Fluorine rubber - the use of the upper temperature of 300 ℃, for chemical lining, senior seals, high vacuum plastic parts.
Q:What insulating material is used for high voltage cables
Etc., can withstand mechanical force and a certain tension. YJLV32 aluminum core XLPE insulated fine steel wire armored PVC sheathed power cable YJV33 copper core XLPE insulated fine steel wire armored PVC sheathed power cable YJLV33 aluminum core XLPE insulated steel tape armored PVC sheathed power cable
Q:What is the 8 ° C rule for insulating materials?
Such as A-class insulation material limit working temperature of 105 ℃, when the ultimate operating temperature of 8 ℃, its life will be reduced by about half, which is 8 ℃ thermal deterioration rules.
Q:What insulating materials are used for high frequency transformers?
Where the water is mainly a resin and solvent or resin, oil and solvent composition, is based on polymer polymer, under certain conditions can be cured into an insulating film or insulation of the important insulation material, applied to high-frequency transformers After the surface, the solvent evaporates, the resin or the resin and the oil form a smooth film, showing the original pattern of the object. Easy to dry and durable, and can acid and oil.
Q:What are the commonly used insulating materials?
Mostly used to make insulating varnishes, winding wires, etc. Insulation materials are made of the above two kinds of materials made of various molding insulation materials, used as electrical appliances of the base, shell and so on.
Q:What are the gas insulation materials?
Gas insulation material refers to air, nitrogen, sulfur hexafluoride and other gases
