Silicone Based Dielectric Cooling Oil
As an insulating and heatdissipating medium, transformer oil is essential for the operation of transformers in power transmission and transformation projects, significantly contributing to the safety of substations. Therefore, the primary functional requirements for transformer oil are effective insulation and heat dissipation, with high withstand voltage and low dielectric loss being key electrical performance indicators. With the progression of highvoltage power transmission technology, transformer oils must demonstrate superior oxidation stability, thermal stability, and resistance to gas precipitation to ensure compatibility with highvoltage conditions. Moreover, controlling trace water and particulate impurities has become increasingly stringent.
Product Details：Low Viscosity Insulation Fluid for HV Transformers
Transformer in the process of charged operation, will produce “copper consumption” and “core loss”. These two parts of the loss are in the form of heat performance. If not the coil of this heat out, it will inevitably make the coil and the iron core of the heat accumulated in the more and more and make the iron core internal temperature, which will damage the coil outside the solid insulation, so as to burn the coil. If the use of transformer oil, then this part of the heat generated inside the coil, first of all, is absorbed by the oil, and then through the circulation of the oil and make the heat emitted, which can ensure the safe operation of the equipment.
