An electrical insulating oil composition having good low temperature characteristics which comprises at least 4 members selected from the group consisting of (a) m-ethylbiphenyl, (b) p-ethylbiphenyl, (c) o-benzyltoluene, (d) m-benzyltoluene, (e) p-benzyltoluene, (f) 1,1-diphenylethane, and (g) 1,1-diphenylethylene; and is characterized in that the proportion of solid phase at a temperature of -40.degree. C. of the electrical insulating oil composition is not more than 45% by weight and the proportion of the total quantity of solid phase is calculated according to the following general equation of solid-liquid equilibrium: ##EQU1## wherein X.sub.i is the equilibrium mole fraction of a component i in the liquid phase of the composition, .DELTA.H.sub.i.sup.f is the heat of fusion (cal.mol.sup.-1), T.sub.i.sup.f is the melting point (K), t is the temperature (K), and R is the gas constant (cal.mol.sup.-1.K.sup.-1).
