An electric device comprising a conductor and a porous conductor insulation impregnated with a dielectric fluid. Where the dielectric fluid comprises;a polymer; anda hydrocarbon-based fluid.The dielectric fluid being composed such that a part of the polymer molecule interacts with the hydrocarbon based fluid or another part in the polymer molecule in such a way that the dielectric fluid;at temperatures within a first low temperature range is in a highly viscous and elastic, essentially gelled, state;at elevated temperatures within a second higher temperature range, is in low viscosity easy flowing and essentially newtonian state; andthat the viscosity of the dielectric fluid is, over a third limited temperature range, the transition range, changed between the low viscosity state and the highly viscous state. The transition range comprises temperatures between the first and the second temperature ranges. |
