ABSTRACT:
An improved oil-filled capacitor which is excellent in low temperature characteristics. The oil-filled capacitor is composed of at least partially a plastics material and is impregnated with an electrical insulating oil which oil is characterized in that it comprises 0 to 100% by weight of a fraction A containing components boiling within the range of 268.degree. to 275.degree. C. (atmospheric pressure basis) and 100 to 0% by weight of a fraction B containing components boiling within the range of 280.degree. to 310.degree. C. (atmospheric pressure basis) which fractions are recovered by distillation from the heavy by-product oil that is produced in the preparation of ethylbenzene by alkylating benzene with ethylene in the presence of an alkylation catalyst and the ratio of the integrated intensity as chemical shift at 120 to 155 ppm of the spectrum measured by C.sup.13 NMR method to the total integrated intensity at 0 to 155 ppm of the spectrum it 80% or higher with regard to said fraction A and the same ratio is 72% or higher with regard to said fraction B.
