FIELD: chemistry.
SUBSTANCE: invention relates to oil refining. The transformer oil contains, wt %: antioxidant additive - up to 0.5 and a basic support - up to 100. The basic support contains, wt %: 30 to 70 support 1 and 30 to 70 support 2. Support 1 is mineral oil obtained from a narrow 250 to 340°C fraction of diesel oil through hydrorefining, hydrodewaxing, hydrogenation with subsequent fractionation. Support 2 is a 280°C to 360°C fraction of isoparaffin oil, obtained from oil paraffin (300°C-K.K fraction) through hydrorefining, hydrodewaxing, hydrogenation of paraffins with subsequent fractionation.
EFFECT: improved viscosity-temperature characteristics, dielectric and electrical insulating properties.
