MEDIUM VOLTAGE HEATING ELEMENT ASSEMBLY

摘要

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.

1. An electric heating element assembly, comprising:
a sheath; a resistive wire; and a dielectric core positioned within the sheath, wherein the dielectric core comprises:
an outer portion comprising a first end; andan inner portion positioned within the outer portion, wherein the inner portion defines a length, and wherein the inner portion comprises:
an interior passageway extending the length of the inner portion, wherein at least a portion of the resistive wire is positioned in the interior passageway; anda second end, wherein the second end is longitudinally offset from the first end of the outer portion; anda groove-and-notch interface between the inner portion and the outer portion.
