1. Environmental Adaptability
Operating temperature range: The operating temperatures required for capacitors vary according to different usage scenarios. For instance, capacitors functioning in high - temperature settings like industrial furnaces, kilns, and automobile engine compartments need to be paired with capacitor oils that have a high flash point, low volatility, and excellent thermal stability. On the other hand, capacitors operating in low - temperature environments such as electronic devices and refrigeration equipment in polar regions should be equipped with capacitor oils having a low pour point. This ensures that the capacitor oils can still operate correctly at low temperatures.
2. Selection of Attention Factors
Breakdown voltage: This represents a key parameter to measure the insulation ability of capacitor oil. When the breakdown voltage is higher, capacitor oil shows more excellent insulation performance in high - voltage scenarios. It can efficiently avoid faults such as short - circuits occurring within the capacitor. Usually, there is a general requirement that the breakdown voltage of capacitor oil must be no less than a specific value, like 40 kV.
