M/DBT Capacitor Oil
Benzyl toluene insulating oil, mainly made up of benzyl toluene, is a kind of specialized insulation material applied in the power industry. It is of great significance in transformers and cables, offering outstanding electrical insulation and cooling capabilities. In contrast to traditional insulating oils, it has more favorable environmental features and longer - lasting durability. This can effectively cut down the frequency of equipment maintenance and boost the operational efficiency.
Benzyl toluene insulating oil is becoming a favored option for capacitors and is slowly replacing traditional insulating oils. Its green characteristics and remarkable electrical performance render it very popular in the market. As the demand for efficient and sustainable materials is on the increase, benzyl toluene insulating oil presents a more reliable insulation solution for capacitors, pushing forward technological development in the power industry.

1. Performance Characteristics
Thermal stability means that it can still keep good insulation properties when the temperature is high (more than 100 °C) or in harsh environments. Because of its high flash point, the possibility of a fire is reduced. For environmental characteristics, new - type capacitor oils, for example, benzyl toluene insulating oil, usually perform better environmentally. With lower volatility and greater biodegradability, they have less influence on the environment. They also comply with international environmental norms and adapt well to the development trend of green power.
2. Quality Index
Kinematic viscosity: Generally speaking, at 40 °C, the kinematic viscosity is about 10 - 20mm²/s. This low - viscosity characteristic ensures that it can flow well at different temperatures. It can circulate rapidly inside the capacitor, achieving the effects of insulation and heat dissipation.
Flash point: The open flash point is usually in the range of 150 °C - 170 °C, and the closed flash point is between 130 °C and 150 °C. Thanks to the high flash point, the capacitor is not likely to catch fire during operation, even in high - temperature environments, thereby increasing the safety of use.
