Bushing Design & Types

  A power transformer's transformer bushings are a crucial part. They offer a secure and dependable link between the high-voltage electrical network and the transformer windings. Bushings serve as insulators and are built to endure significant mechanical and electrical strains. The many designs for transformer bushings and their uses will be covered in this article. Oil-impregnated Paper Bushings The most popular kind of bushing used in power transformers is oil-impregnated paper. They are made up of a porcelain insulator supporting a paper tube that has been impregnated with insulating oil. These bushings are a common option in the sector since they are dependable and affordable. Resin-impregnated Paper Bushings Oil-impregnated paper bushings and resin-impregnated paper bushings both function similarly. However, they use epoxy resin as an insulating substance rather than oil. These bushings last longer and are more hygienic and contaminant-resistant. Composite Bushings Composite m...
