High-performance dielectric oils used for insulation and cooling of power transformers, circuits, and resistors:
– Mineral dielectric oils derived from naphthenic bases;
– Biodegradable ester-based dielectric fluids; The use of alternative fluids is becoming increasingly widespread in applications, not only due to their ‘green’ image but also due to their formulation base. The technical capabilities of esters are nearly limitless, and biodegradable esters have demonstrated exceptional records of operational performance in lubricating distribution transformers and power transformers.
