1. Environmental Adaptability
Operating temperature range: Capacitors in different application scenarios demand different operating temperatures. Take, for example, capacitors used in high - temperature environments, including industrial furnaces, kilns, and the engine compartments of automobiles. These capacitors must use capacitor oils with a high flash point, low volatility, and good thermal stability. In contrast, for capacitors working in low - temperature environments, like electronic equipment and refrigeration equipment in polar areas, it is necessary to select capacitor oils with a low pour point to guarantee that the capacitor oils can function normally at low temperatures.
2. Selection of Attention Factors
Breakdown voltage: It serves as an important metric for assessing the insulation property of capacitor oil. A higher breakdown voltage indicates that capacitor oil has better insulation performance under high - voltage situations. This helps to effectively prevent internal capacitor faults such as short - circuits. Generally speaking, the breakdown voltage of capacitor oil is commonly required to be not lower than a certain value, say 40 kV.
