Abstract
A tamper-resistant three-phase padmounted transformer is provided including a tank having electrical connections mounted on one wall thereof, and a cabinet fixedly attached to the tank forming a cabinet-to-tank interface therebetween. An elongated P-shaped gasket is positioned at the interface so as to completely fill such interface, and a rib is secured to the cabinet for overlying the interface to form a tamper-resistant cabinet-to-tank interface which prevents the intrusion of extraneous objects into the interior of the cabinet.
