Brief instruction:

The pure porcelain bushing is mainly used for transformers with 10kV and below.

 It is a conductive copper rod pierced in the porcelain bushing, and the porcelain bushing is air insulated.

 The oil-filled bushing is mostly used in 35kV transformer

FAQ:

1. What is a bushing in a transformer?

   A bushing is an electrical insulator that allows the safe passage of electrical conductor current.

   It is similar to any insulator which surrounds a conductor, to help it prevent from making any untoward incident.

   A transformer has two windings – primary and secondary (HV and LV).

2. What is the difference between porcelain and epoxy bushing?

   Epoxy Bushings don't require assembly.

   Porcelain bushings require assembly of several components to build the final product.

   Aside from the extra expenses associated with the build, the assembly process also increases the risk of

   flaws and failure in the bushing's duty to insulate the conductors.
