Naphthenic Transformer Oil Kinematic Viscosity of Capacitor Oil
Benzyltoluene has excellent properties such as good insulation and dielectric characteristics, low viscosity, a high boiling point, and high thermal stability. It is extensively used in the electric power and petrochemical industries as a capacitor impregnating agent and heat - conducting oil. In addition, because of its strong capacity to absorb gas and high hydrogen storage density, it shows great potential as a hydrogen storage carrier in the new energy field. With the continuous development of industrial technology, the domestic demand for benzyltoluene products with outstanding performance is certain to rise.
Product Details：Kinematic Viscosity of Capacitor Oil
Benzyl chloride and toluene react to yield monobenzyltoluene (MBT) and dibenzyltoluene (DBT). The resulting MBT and DBT exhibit good thermal stability, a broad operating temperature range, no corrosiveness, and no strange smell. They are heat - transfer oils with outstanding comprehensive performance.

1. Quality Index
Pour point: Usually, it is around -40 °C to -50 °C. A low pour point ensures that the insulating oil can stay in a liquid state in low - temperature environments. This prevents any negative impacts on the capacitor's performance that could be caused by the oil solidifying.
Acid value: The acid value is typically less than 0.05mgKOH/g. A lower acid value indicates better chemical stability of the insulating oil. This means it will have less corrosive effects on the electrodes and insulation materials within the capacitor.
Moisture: Generally, the moisture content is required to be less than 50ppm. If the moisture is excessive, it can greatly reduce the insulating oil's insulation performance, increase dielectric loss, and may even lead to internal breakdown of the capacitor.
2. Application Areas
Power capacitors: A large number of power capacitors are applied in the reactive power compensation and filtering within power systems. Capacitor oil serves as the insulation and cooling medium. It ensures the stable operation of power capacitors under high - voltage and high - current working conditions. By doing so, it improves the power factor of the power system, reduces the line loss, and enhances the power quality.
