Low Viscosity Insulation Fluid for HV Transformers
In power transmission and transformation projects, transformer oil functions as a key insulating and heatdissipating medium for transformers, significantly influencing the safe operation of substations. Thus, the basic functional requirements for transformer oil include efficient insulation and heat dissipation, while high withstand voltage and low dielectric loss are critical electrical performance requirements. As highvoltage power transmission technology evolves, transformer oils must also provide high oxidation stability, thermal stability, and good resistance to gas precipitation to adapt to highvoltage conditions. Furthermore, stringent control over trace water and particulate impurities has become a priority.
Product Details：Silicone Based Dielectric Cooling Oil
In the operation of a transformer under load, “copper consumption” and “core loss” generate heat. If this heat is not removed from the coils, it will accumulate, causing the temperature within the iron core to rise. This can damage the solid insulation surrounding the coil, potentially leading to coil burnout. The use of transformer oil helps manage this heat; the oil absorbs the heat generated within the coils and then circulates to dissipate it, ensuring the equipment operates safely.

2. Oil Change Inspection
Evaluating the operational condition of a transformer involves reviewing its history and maintenance logs. If there have been recurrent failures or signs of reduced performance, it may be essential to assess the quality of the oil and consider a replacement. Furthermore, it’s important to judge based on the transformer's design life and age. Should the transformer be approaching or exceeding its intended lifespan, replacing the transformer oil could be vital for ensuring ongoing safe operation.
