A padmounted transformer having an improved terminal cover-to-tank interface, which improves tamper resistance, improves corrosion resistance, and reduces manufacturing costs. The interface is formed by two equal, opposite facing acute angles in the cover, and a single obtuse angle in the adjacent tank, with the obtuse angle being substantially equal to 180 DEG minus the value of an acute angle. Closure of the terminal cover causes a leg of the obtuse angle to enter the vertex of an acute angle, to create a tortuous path for elongated foreign objects, such as a wire, and for providing a sloping surface which causes prybars to slide out of the interface seam.
