The present disclosure provides a vehicle electric propulsion system, an electric machine, and a method of assembling the same. The electric machine includes a stator, a rotor, and stator windings all disposed within a housing thereof. The stator defines a central bore elongated along a longitudinal axis, and a plurality of slots disposed circumferentially around the central bore. The rotor is held within the central bore and rotates relative to the stator. The stator winding includes a core conductor, an insulating layer surrounding the core conductor, and a conductive shielding layer surrounding the insulating layer. The stator winding extends through the slots of the stator. The stator winding includes an in-slot portion located within the slot of the stator and an end winding portion located outside the slot. The conductive shielding layer surrounds the insulating layer along both the in-slot portion and the end winding portion of the stator winding.
