ABSTRACT:
A finished transformer core (48) includes a core (2) of wound amorphous transformer core material (4) to which rigidifying bonding material (22) is applied to the ends (12, 14) of the core. The bonding material does not cover the entire ends but leaves gaps (24) to permit fluid flow between the ambient environment and the interlamination voids (16) which exist between the layers (18, 20) of the wound material. The core, rigidified by the bonding material, is housed within a fluid permeable containment assembly (28). The containment assembly typically includes fluid permeable filter material (32, 34, 36, 38) which allows transformer oil and air to pass through the material but will trap solid particles of core material within the containment assembly.
