ABB offers a broad range of bushings for transformers , reactors, switchgear, and traction and wall applications in both oil impregnated paper (OIP) and resin impregnated paper ( RIP) . ABB is continually addressing major technology trends and market challenges in the transformer. The two most common types of bushings used on transformers as main lead entrances are solid porcelain bushings on smaller transformers and oil-filled.

The windings (both hv and lv) of any transformer is sealed in a tank filled with transformer oil.

There must be a way to access those windings, since the tank is made of iron and iron is conductive in nature the tank must be insulated from the con. Before diving into details, the basic idea of a high voltage line being near to earth creates strong electric field. This May lead to flashover of charge and undesirable stress in the conducto. Above kV the mounting flange is equipped with a voltage tap. Shatter Resistant Inboard End.

Every Trench COTA bushing is offered with a shatter resistant in-board end insulator. These insulators are less susceptible to damage from handling. They will not shatter like porcelain preventing major transformer repair costs.

A transformer bushing is an insulating structure that facilitates the passage of an energised conductor through the grounded tank of the transformer.
