Abstract: This paper investigates dry-type resin-impregnated fiber bushings from the perspectives of structural configuration, manufacturing process, and engineering application. First, the structural system of this type of bushing is described, featuring capacitive solid insulation as the core and composite external insulation as the outer protective system. Second, the key manufacturing stages—including capacitor core winding, drying and curing, and final assembly and sealing—are analyzed, with emphasis on the main control factors affecting insulation reliability and production consistency. Finally, based on a comparison with oil-paper capacitor bushings, the advantages of dry-type resin-impregnated fiber bushings in safety, environmental adaptability, maintenance mode, and structural compactness are summarized, while their limitations in dielectric loss, temperature resistance, process window, and manufacturing cost are also discussed. The results show that this type of bushing has considerable engineering value in improving equipment safety and reducing maintenance complexity; however, its performance depends strongly on material selection and process control. This study can provide reference for engineering selection, design optimization, and quality control of such bushings.
