ABSTRACT:
An improved electrical heating element for a high-temperature furnace including a support structure and an electrical-heating assembly. The support structure includes a plurality of thin, flat, non-conductive plates each having a plurality of spaced apertures therethrough and a plurality of non-conductive spacers smaller than the plates with one spacer interposed between each pair of adjacent plates. The electrical-heating assembly includes a plurality of elongated electrical conductors, preferably U-shaped, each leg extending through one aperture in each plate radially outwardly of the spacers. The conductors are supported by and extend between the plates and the ends of the conductors are interconnected so that the conductors as interconnected define a single tortuous electrical path radially outwardly of the spacers. The [interconnection] interconnections between the conductors maintain the support structure in assembly.
