1. Environmental Adaptability
Operating temperature range: Different use scenarios require different operating temperatures for capacitors. For example, capacitors working in high temperature environments, such as industrial furnaces and kilns, automobile engine compartments, etc., need to choose capacitor oils with high flash point, low volatility and good thermal stability; capacitors working in low temperature environments, such as electronic equipment and refrigeration equipment in polar regions, etc., need to choose capacitor oils with a low pouring point in order to ensure that capacitor oils can still work properly at low temperatures.
2. Selection of Attention Factors
Breakdown voltage: It is a crucial indicator for evaluating the insulation capacity of capacitor oil. The higher the breakdown voltage, the better the insulation performance of capacitor oil under high - voltage conditions. This can effectively prevent faults like short - circuits inside the capacitor. Generally, it is required that the breakdown voltage of capacitor oil should not be lower than a certain value, for example, 40 kV or so.
