A PRC bushing is a Paper-Resin-Capacitor type bushing. A capacitance graded core is wound around a center conductor which is created with high dielectric paper and conductive layers. This bushing core is impregnated with a high dielectric epoxy resin. Since the core is completely encapsulated in resin, lower external insulation is not needed. A porcelain insulator is used for external insulation above the flange. Transformer oil may be placed between the upper porcelain and PRC core or a dielectric gel is used where the bushing construction is considered oil-free. PRC bushings are available starting at 15kV- 600A through 69kV-2000A. The C1 power factor reading for a PRC bushing should be 0.85% or below per the IEEE bushing standard.
