Abstract
A medium-voltage heating element assembly. The medium-voltage heating element assembly can include a dual core having an inner core and an outer core. Segments comprising the inner core and the outer core can be staggered. Furthermore, the dual core can include a notch-and-groove interface to prevent axial rotation of the inner core and/or inner core segments relative to the outer core and/or outer core segments. A bushing of the heating element assembly can include a stepped region, and the bushing can interface with the dual core along the stepped region.
