A new procedure for the double impregnation of electrical condensers comprising at least one bobbin and container, by the following stages :- a) Impregnation of the bobbin with a dielectric fluid (A) then,optionally, subjection to a thermal treatment ; b) Elimination of the excess fluid (A) ; c) Filling of the container containing the impregnated bobbin with a gelifiable composition comprising a polyol, a polyisocyanate, possibly a catalyst, and the dielectric fluid (A) ; d) Gelification of the gelifiable composition. Also claimed, is the condenser prepared by this process. |
