Difference between Core Type Transformer and Shell Type Transformer

A transformer is an electrical device that changes the voltage of an alternating current (AC) power source. Core type and shell type are two common types of transformers.

The main difference is that in a core type transformer, the primary and secondary windings are wound around an iron core while in a shell type transformer, the primary and secondary windings are wound around the same iron core but separated by a metal partition.

Before we move to the differences, let’s understand what are Core Type Transformer and Shell Type Transformer:

• Core Type Transformer: A core type transformer is an electrical device in which the primary and secondary windings are wound around an iron core. The core provides a path for the magnetic flux and helps to increase the transformer’s efficiency.
• Shell Type Transformer: A shell type transformer electrical device in which the primary and secondary windings are wound around the same iron core but separated by a metal partition. The metal partition helps to reduce the leakage flux, but it also reduces the transformer’s efficiency.

Now, let’s move to Core Type Transformer vs Shell Type Transformer:

Major differences between Core Type Transformer and Shell Type Transformer

Core Type Transformer	Shell Type Transformer
Core type transformer is more efficient than shell type transformer.	Shell type transformer is less efficient than core type transformer.
Core type transformer is more expensive than shell type transformer.	Shell type transformer is less expensive than core type transformer.
Core type transformer has more space for winding.	Shell type transformer has less space for winding.
Core type transformer has better cooling.	Shell type transformer has poor cooling.
Core type transformer can handle more voltage than shell type transformer.	Shell type transformer can handle less voltage than core type transformer.

 

That’s it.
