insulation flexible mica paper roll

Q: There are a lot of online about this, but still do not understand. If the insulation resistance is high enough, hit the pressure should also be qualified ah. There is insulation test itself when the current flow is not large, because the rock table resistance is great. But hit the pressure, I do not know is not a direct high pressure drop in the test product above, there is no great resistance to interference?: Insulation resistance is measured with an insulation resistance tester (10000V or less) or an insulation shaking table (2500V or less). Since the test voltage is low, many insulation defects are not easily found; the withstand voltage test test voltage is high and the high pressure equipment is easily found Insulation defects;

Q: What insulating materials are used for transformers: With the largest number of cardboard, as well as laminated wood, insulating paper, transformer oil, large oil-immersed transformers are mostly oil - paper insulation.

Q: Who knows what are the ability of 1300 degrees above the high temperature, insulation materials?: Heat-resistant polymers can be used as high temperature resistant film insulation materials, high temperature resistant fibers, high temperature resistant coatings, high temperature adhesives. In accordance with the high temperature of the time, but also sub-instant high temperature materials and high temperature materials for a long time. The former in 1000 ~ 10000 ℃ can withstand a few seconds to a few minutes.

Q: What insulating materials do you need for power tools?: Reinforced insulation: the voltage between the live parts and the accessible housing is 3750V, such as the voltage between the brush and the cover surface; double insulation: basic insulation + additional insulation. Main insulating material: green paper or DMD Insulation paper for basic insulation; shaft insulation and plastic housing for additional insulation; rotor insulation end plate, stator insulation end plate, used to control the creepage distance and electrical clearance; brush grip bakelite powder, used to strengthen the insulation; other parts (Power plugs, commutators, switches, etc.) These are pressure requirements.

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 are the gas insulation materials?: In addition to air, nitrogen, carbon dioxide and sulfur hexafluoride gas, there are other gases used for insulation. CCl2F2 (freon-12) was used as an insulating in certain high-energy physical devices. CCl2F2 breakdown strength and SF6 similar, but because of its high liquefaction temperature, and the spark will make CCl2F2 precipitation of carbon particles, therefore, has been replaced by SF6. In hydrogen-cooled generators, hydrogen is also used as insulation in addition to cooling media.

Q: What is the main purpose of insulating materials?: As the insulating material has a certain degree of insulation strength, a variety of electrical equipment, all kinds of safety equipment (electrical pliers, test pen, insulated gloves, insulation rods, etc.), a variety of electrical materials, factories are required to allow a certain voltage, For the rated voltage. The voltage to be used shall not exceed its rated voltage value in order to avoid accidents.

Q: What is the DMD insulation material?: DMD (Dacron / Mylar / Dacron) full name polyester film polyester fiber non-woven soft composite foil, is a two-layer polyester non-woven fabric in the middle of a layer of insulated polyester film composite made of three insulation materials.

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 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.
