Product Description:

 1. Introductions:

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 line-frequency 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.

Typical applications of mica heating elements are air heaters, enclosure systems, food service equipment, process and packaging equipment.

Q:What type of enameled wire and insulation material is used for the compressor
Small and medium-sized closed, semi-enclosed refrigeration compressors are used for the specific enameled wire specifically (QF) series.
Q:What insulating material is best `?
Gas insulation material has a high ionization field strength and breakdown field strength, after the breakdown can quickly restore insulation performance, chemical stability, non-combustible, non-explosive, non-aging, non-corrosive, easy to discharge decomposition, and greater heat capacity , The thermal conductivity, and the flowability are all. The air is the most widely used gas insulating material, for example, between the overhead wires of the AC and DC transmission lines, and the overhead wires are insulated by air. The high voltage standard capacitors also use gas insulating media (SF6) .SF6 is also used in the manufacture of high-voltage circuit breakers, metal-enclosed combination of electrical appliances, gas-insulated transmission pipeline cables and gas-insulated transformers, etc., the use of high-pressure nitrogen or carbon dioxide.
Q:Wear-resistant, high temperature, insulation materials which
Hexagonal boron nitride - good heat resistance, thermal stability, thermal conductivity, hardness is not high, the only easy machining of ceramics. Is the ideal heat dissipation material and high temperature insulation material. For high temperature containers, semiconductor thermal insulation materials, high temperature bearings, thermocouple casing. Cubic boron nitride - hardness close to the diamond, excellent wear-resistant materials. For high-speed cutting tools, such as drawing die.
Q:What insulating material is used for high voltage cables
YJLV23 Aluminum core XLPE insulated steel tape armored PVC sheathed power cable YJV32 copper core XLPE insulated fine steel wire armored PVC sheathed power cable indoor, tunnel, cable trench, shaft or buried
Q:What is the 8 ° C rule for insulating materials?
The service life will be greatly shortened, such as ATR insulation material limit working temperature of 105 ℃, when the ultimate working temperature of 8, the life will be reduced by about half, which is the so-called 8 ℃ thermal deterioration rules
Q:What insulating materials do you need for power tools?
Insulation system of power tools can be divided into basic insulation, additional insulation, reinforced insulation, double insulation. Basic insulation: enameled wire and iron core between the insulating paper (paper for the green paper or DMD insulation paper) is the basic insulation, Withstand voltage is 1250V;
Q:The role and definition of insulating materials
The main indicators affect the performance of insulating materials 1, insulation resistance, resistivity: resistance is the reciprocal of conductance, the resistivity is the resistance per unit volume. The smaller the conductivity of the material, the greater the resistance, the reciprocal relationship between the two, for the insulation material, always want the resistivity as high as possible. 2, the relative dielectric constant and dielectric loss tangent:
Q:What insulating materials are used for high frequency transformers?
Silicon steel lacquered lacquer can be divided into surface enamel and varnish, drying and drying and self-drying. High-frequency transformer insulation paint choice should have good dielectric properties, a higher insulation resistance and electrical strength; and electrical appliances use the environment to match the heat resistance; good mechanical properties and wear resistance; good thermal conductivity Sexual and moisture-proof performance; economical, reliable, wide range and so on.
Q:What are the gas insulation materials?
The relative breakdown strength of air (at air 1) at the standard pressure (101335Pa) is as follows: nitrogen, 1; hydrogen, 0.5; carbon dioxide, 0.9; sulfur hexafluoride, 2.5; freon-12,2.7 The
Q:What are the electrical insulation materials
Electrical insulation materials are wood, cotton, paper, oily paint, asphalt paint, polyester film, glass cloth, mica, glass fiber, asbestos, composite silicon organic polyester paint, quartz, glass, porcelain material.
