ABSTRACT:
A power resistor including a resistance element of metal ribbon formed into an edgewound helix, and an internal three-point support structure axially disposed within the interior of the helix. The support structure includes three insulating assemblies each having a plurality of insulators secured by longitudinal compression springs to a support bar. The support structure also includes a pair of spreaders located at opposite ends of the helix, each having three radially extending arms. Assembly of the resistor includes the steps of inserting the insulating assemblies into the interior of the helix, radially spreading the insulating assemblies against the interior of the helix, and welding the ends of the support bars to the extending arms of the spreaders.
