Abstract (en)

[origin: EP3754674A1] The present disclosure relates to an insulating liquid (26) for an enclosure (24) intended to enclose an inductive device comprising a winding (20) surrounded by solid insulation (22) as well as to an inductive arrangement comprising a container (24) with such an inductive device (12) and insulating liquid (26). The insulating liquid (26) comprises a first main component in the form of a first oil having an equilibrium resistivity of at least 10<sup>13</sup> ohm metres and at least one second auxiliary component in the form of a second oil or additive having a lower equilibrium resistivity causing the equilibrium resistivity of the insulating liquid to be at least 10<sup>11</sup> ohm metres and at most half the value of the equilibrium resistivity of the first oil when in use in the enclosure.
