Abstract: A transformer includes an enclosed tank having an interior and an enclosed radiator spaced from the tank and in fluid communication with the interior. The radiator includes two panels joined to define a substantially enclosed space. The panels have opposing faces and bottom ends. The bottom ends of the panels are joined together by a first weld and portions of the opposing faces of the panels are joined together by a plurality of second welds. The first weld and the plurality of second welds are constructed and arranged such that when an over-pressure condition occurs in the tank and thus in the radiator, the second welds will break generally uniformly permitting the panels to balloon generally uniformly, directing a rupture of the radiator to occur at the first weld, without any rupture of the tank occurring.
