Abstract (en)

[origin: WO2013182227A1] Tank for a liquid-filled transformer or inductor, comprising: a) an outer tank casing (2) comprising a bottom part (3); b) an inner tank casing (5), enclosed by the outer tank casing (2) at a distance (4), wherein the outer tank casing (2) and the inner tank casing (5) are formed from metal; c) a plastic or polymer material (7), which is incorporated in an intermediate space (6), bounded by the inner surface (14) of the outer tank casing (2) and the inner surface (13) of the inner tank casing (5), and at least partially fills this intermediate space (6), wherein the plastic or polymer material and the adhesion thereof to the inner surfaces (13, 14) is designed such that d) shearing forces are transmitted between the inner and outer tank casings (2, 5) and that e) the transmission of structure-borne sound that is generated in the case of operation of an active part (10) arranged in the interior space (9) of the tank between the inner tank casing (5) and the outer tank casing (2) is inhibited.
