Q:What are the commonly used insulating materials?
Mainly used for motor, electrical winding insulation, switch the bottom plate and insulators, etc. Organic insulation materials are: shellac, resin, rubber, cotton yarn, paper, linen, rayon,
Q:The electrical equipment in the classroom which uses insulating material
Classrooms in the electrical equipment are used insulating material, but with the number and location of different.
Q:What is the thermal aging and electrical aging of insulating materials?
Environmental aging, also known as atmospheric aging, is due to ultraviolet light, ozone, salt spray, acid and other factors caused by pollution of chemical aging, which is the main reason for ultraviolet light. Thermal aging more common in low-voltage electrical appliances, the mechanism is under the action of temperature, the insulating material in some volatile components escape, the internal components of oxidative cracking, thermal cracking, hydrolysis, molecular chain polymerization and other chemical changes, and gradually lose insulation properties.
Q:What is the electrical performance of insulating materials
Such as the rated voltage, current, active power, reactive power, resistance, capacitance, inductance, conductance; semiconductor is famous, DC magnification, AC magnification, rectified current, reverse breakdown voltage, forward voltage , The junction voltage, the noise figure, the characteristic frequency, the cut-off frequency, the dissipation power ... the IC is also very large, the maximum working voltage, the op amp's pendulum speed, the bandwidth, the distortion coefficient, the ADC conversion rate, , The resolution of plastic in the field of electrical applications is extremely extensive, its role is mainly two aspects, one as electrical insulation materials, two for the mechanical structure of materials. These materials are used in the field of electrical engineering, mainly in the electrical, electrical and electrical industries.
Q:Wear-resistant, high temperature, insulation materials which
Epoxy, temperature from 100-400 degrees, processing more convenient. Ceramic is the best and cheap.
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:What insulating material is used for high voltage cables
Features: The rated voltage of the cable is 6kv. The long-term operating temperature of the cable is + 65 ° C. The minimum bend radius of the cable is 6 times the cable diameter.
Q:What is the insulating material in the middle of the connecting wire?
Looked for a long time to understand your problem, I can see with a relatively thin tube into the insulation, the insulation tube into a plug in the insulation of the skin. Or for the wire, without the foreskin of the wire is not safe
Q:What are the electrical insulation materials
Many types of insulating materials, can be divided into gas, liquid, solid three categories. Commonly used gas insulation materials are air, nitrogen, sulfur hexafluoride and so on. Liquid insulation materials are mainly mineral insulating oil, synthetic insulating oil (silicone oil, dodecyl benzene, polyisobutylene, isopropyl biphenyl, diaryl ethane, etc.) two categories. Solid insulation materials can be divided into organic, inorganic two categories. Organic solid insulation materials include insulating varnishes, insulating glue, insulating paper, insulating fiber products, plastic, rubber, lacquered lacquers and insulating impregnated fiber products, electrical thin films, composite products and adhesive tape, electrical laminates and so on. Inorganic solid insulation materials are mainly mica, glass, ceramics and their products. In contrast, solid insulation material variety, but also the most important. Different electrical equipment requirements for the performance of insulating materials are focused. High-voltage electrical equipment such as high-voltage motors, high-voltage cables and other insulation materials require high breakdown strength and low dielectric loss.
Q:Who knows what are the ability of 1300 degrees above the high temperature, insulation materials?
High temperature resistant materials include refractory and heat resistant materials, inorganic compounds, and polymer materials. Refractory material usually refers to the resistance of 1580 ℃ above the temperature of inorganic materials. They are built kilns, combustion chambers and other building materials that require high temperatures. General use of quartz sand, clay, magnesite, dolomite as raw materials and made, such as refractory cement, magnesia and so on. Broadly speaking, inorganic refractory, heat-resistant materials refers to the high hardness of these compounds, good brittleness, good chemical resistance, and the melting point of 1500 or more. Mainly divided into metal and non-metallic compounds and non-metallic compounds.
