Abstract Corrugated spacers are disposed between winding layers of a transformer winding to enable circulation of air between the layers. Elongated reinforcing rods are placed in corrugations at the corner regions of the winding and adjacent wedges between the winding and the transformer core. Dielectric sheaths of relatively high dielectric constant are disposed between the outermost and innermost winding layers while relatively low dielectric constant sheaths are placed between adjacent pairs of interior layers, thereby to equalize the distributed capacitance between adjacent layers. A dielectric barrier between the high and low voltage windings of a transformer consists of a sheath of dielectric layers wherein the inner and outermost layers have a higher dielectric constant than the interior layers.
The device of claim 1 wherein each pair of adjacent concentric winding layers has one of said corrugation members therebetween.
