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?: Because the voltage generated by the withstand voltage test is generally greater than twice the rated voltage of the electrical equipment, and the insulation resistance test voltage value and the rated voltage is similar. And the withstand voltage test for the alternating current, insulation resistance test for the DC. Will have a certain impact on its test results.

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: What kind of insulation is the insulating: Ordinary heat conduction is made with fiberglass PP2. High thermal conductivity materials are made of thermally conductive

Q: What insulating materials are used for transformers: Dry type transformers before the 1960s are mainly B-type insulation of the open-type dry-type transformers, product model for the SG type. When there is no foil coil, the low pressure for the majority of multi-root and around the layer or spiral coil, high pressure for the pie coil. Wire for the double glass envelope or single glass fiber package enamel enameled wire. The rest of the insulating material is mostly phenolic glass fiber materials. The impregnation process for the room temperature, atmospheric pressure with B-class insulation impregnated paint were high and low pressure coil impregnation and drying at the temperature (drying temperature does not exceed 130 ℃). Although this dry-type transformers than oil-immersed transformers in the fire performance has made great progress, but its moisture, anti-pollution performance is worrying. Is no longer produced. Nevertheless, its successful electrical, magnetic, thermal calculations and structural design have laid a good foundation for the new H-class insulated open-ended transformers that have evolved later.

Q: What insulating materials do you need for power tools?: Additional insulation: insulation between the rotor core and the mandrel (insulating plastic powder), between the stator core and the plastic housing shell, is the additional insulation withstand voltage of 2500V;

Q: What is the insulating material in the middle of the connecting wire?: With a transparent tape isolation, with hot melt adhesive fixed thread, with heat shrink tube insulation, a lot of ways ah.

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: 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 is the thermal aging and electrical aging of insulating materials?: Insulation materials in electrical equipment during the operation, due to the long-term effects of various factors, there will be a series of irreversible physical and chemical changes, resulting in its electrical performance and mechanical properties decline, commonly known as aging. There are many factors that affect the aging of insulating materials. The main aging forms are environmental aging, heat aging and electrical aging.

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.
