Abstract (en)
[origin: US7833440B2] The invention relates to a high-performance dielectric oil comprising approximately 75 to 95% by volume of a naphthenic oil and approximately 5 to 25% by volume of an ester oil, in particular a synthetic ester oil and more preferably an oil of the family of polyolesters. The high-performance dielectric oil may be used in high-voltage electrical equipment such as power, measurement, distribution or traction transformers, tap changers, bushings, distributors, oil-immersed circuit breakers, power capacitors, cables, etc.
