Transformer bushings are one main part of transformers used in electrical device, change the high voltage to low voltage for persons’ usage.

Transformer bushings

What is the transformer?
Transformer is an electrical device connecting two or more electrical circuit to each other with an electromagnetic induction. It transfers the energy from one electrical circuit to another with an electromagnetic field, generally keep same energy to use. The transformers are the machines making the requested change in the voltage and current values at a certain power of electricity energy.

Used on transformer insulator, called transformer bushings or bushing insulator for supporting and insulating, Medium Voltage Distribution/Power Transformer Types:
◆ Epoxy Cast Resin Dry Type Transformers
◆ Hermetic Type Transformers
◆ Expansion Tank Transformers

The types of Transformer bushings
◆ Current transformer bushing
◆ Voltage transformer bushing
◆ Oil-immersed transformer bushings

Current transformer is a gauging transformer reducing the primer current to the secondary current with a certain rate and with zero degree difference between the primer current and secondary current.

Transformer bushings are usually used with electrical insulator in electrical system, transformer can provided suitable voltage for electrical equipment.
