Dimethyl silicone oil is a transparent, colorless, odorless, tasteless, and non-toxic oily liquid, possessing excellent characteristics such as high flash point, low freezing point, good thermal stability, and resistance to high and low temperatures. Thanks to these properties, it has been widely used in the electromechanical industry, covering various aspects including insulation, lubrication, shock resistance, dustproof oil, dielectric liquid, and heat carrier. In a wide range of equipment such as motors, electrical appliances, electronic instruments, transformers, capacitors, and television scanning transformers, dimethyl silicone oil acts as an impregnating agent, demonstrating outstanding insulation and protective performance. It can withstand extreme high and low temperatures, effectively resist electric arc corona and corrosion, ensuring the stable operation of equipment under harsh conditions. With the use of dimethyl silicone oil, the reliability and service life of equipment can be significantly improved, while maintenance costs are reduced. In various precision machinery, instruments, and meters, the shock resistance and damping characteristics of dimethyl silicone oil play a vital role. It can stabilize instrument readings, ensuring the accuracy and stability of measurements. Especially in scenarios such as airplanes and automobiles, where there are strong mechanical vibrations and significant changes in environmental temperature, dimethyl silicone oil can significantly reduce the interference of vibrations on instruments, ensuring their normal operation and providing accurate readings for operators. In the landing devices of airplanes, dimethyl silicone oil is used as the medium for liquid springs, realizing an innovative application. This kind of liquid spring can provide effective cushioning when airplanes land, absorbing the impact force to ensure safe landing. The high compressibility and good thermal stability of dimethyl silicone oil make it perform outstandingly in this application, providing important guarantees for aviation safety. From these application cases, it can be seen that dimethyl silicone oil is an all-rounder in the electromechanical industry. It not only has excellent insulation and protective capabilities but also plays a key role in shock resistance, damping, and liquid springs, providing strong support for the stable operation and high-performance performance of electromechanical equipment.
