Comparison of Core Type and Shell Type Transformer

Q. Difference between core type and shell type transformer.

Sr. No.	Core Type	Shell Type
1.	Figure (A) In this type, the windings enclose the whole core.	Figure (B) In this type, the core encloses the windings.
2.	Average length of the core is more.	Average length of core is less.
3.	Magnetic flux has only one continuous path.	flux Magnetic distributed into two paths.
4.	Suitable for high voltage / less output.	Suitable for less voltage / high output.
5.	Easy for repairs.	Difficult for repairs.
