Abstract

An oil-cooled 50DN stator terminal insulator comprising an insulating base member with an insulating bushing extending from a top surface of the base member for insulating one of multiple stator lead terminals, and associated parts kit. The insulator includes a central aperture for receiving the terminal such that the insulator and the terminal are independently movable with respect to the remaining terminals of the stator in order to facilitate assembly of the stator and a rectifier housing having a plurality of openings extending from an internal surface to an external surface. The ability of the terminal with the insulator to move independent of the remaining terminals provides the stator with resistance to vibrations.
