ASTM D3487 Insulating Oil
The insulating liquids composed of monobenzyl toluene and dibenzyl toluene are vital electrical insulation materials frequently used for capacitor insulation and cooling. Their main component, benzyl toluene, confers outstanding electrical insulation properties. It can effectively block current leakage, guaranteeing the stable operation of capacitors. In comparison to traditional capacitor oils, benzyl toluene insulating oils display better thermal and chemical stability in high - temperature and humid environments. This leads to an extension of the capacitors' lifespan.
Product Details：ASTM D3487 Insulating Oil
Monobenzyl toluene and dibenzyl toluene insulating liquids play a crucial role in electrical equipment, especially in capacitors. As an efficient insulating fluid, it not only provides excellent electrical insulation but also offers good cooling effects. Compared to conventional capacitor oils, benzyl toluene insulating oils have higher environmental friendliness and durability, maintaining performance under extreme conditions and enhancing the overall reliability and efficiency of capacitors.

1. Selection of Attention Factors
Flash point: flash point is the capacitor oil in the specified conditions heated to its vapor and air mixture in contact with the flame, can occur the lowest temperature of flash fire.Higher flash point can improve the safety of capacitor oil, reduce the possibility of fire and other hazards in the process of use, the general requirements of the flash point is not less than 130 ℃.
2. Environmental Adaptability
Humidity and altitude: in a high humidity environment, capacitor oil should have good water resistance to prevent moisture from invading the inside of the capacitor, affecting the insulating properties; at high altitude, due to thin air, heat dissipation conditions become worse, need to choose a good heat dissipation performance, low dielectric loss of the capacitor oil.
