IMPREGNATION EQUIPMENT

An impregnation facility is provided to prevent hardening of insulating oil loaded in an inner chamber and an outer chamber by arranging a plurality of heating members on an inner side of the inner chamber. An inner chamber(14) is loaded inside an outer chamber(12). Through holes(18, 20) are formed in both sides corresponding to the outer chamber and the inner chamber. A product(16) passes the through holes. A supply pipe(28) supplies insulating oil(24) to the inner chamber. A vacuum pipe(30) is connected to the inner chamber at a position separated from the supply pipe, and is connected to a vacuum pump(32). A recovery pipe(22) communicates the inner chamber with the outer chamber. A power unit(26) is positioned on the recovery pipe, and transfers the insulating oil which is in the outer chamber to the inner chamber.
