Difference between core type and shell type transformer

Difference between core type and shell type transformer

Core type transformer

Shell type transformer

1.       In this type transformer has both side winding of the core. Which means it has both arm winding
In this type transformer winding installed in mid arm of the core. Simply it is installed in mid-point of the core.
2.       In this type transformer has only one path of the magnetic circuit or it has one path two flow of flux.
In this type transformer has two path of the magnetic circuit or it has two flux path.
3.        In this type transformer has similar core side area. Its core side is similar than shell type transformer. It is half than shell type transformer.
In this type transformer has different area of core side. Its core side area is dissimilar.
4.       It has two arm of core or its core has two core arms.
It has three core arms or it has three arms of core.
5.       In this type transformer has maximum leakage flux. It has more leakage flux or more losses in this type transformer.
In this type transformer has minimum leakage flux. it has less leakage flux. It is better than shell type transformer.
6.       In this type transformer give less output. In these type transformer losses is more than shell type transformer.
In this type transformer give more output than core type transformer. In these type transformer losses is less than core type transformer.
7.       In this type transformer, transformer losses (copper losses, iron losses) are more than shell type transformer.
In this type transformer, the transformer losses (copper losses, iron losses) are less than core type transformer.
8.       Maintenance of this type transformer is simple than shell type transformer. Its repair is also is simple.
Maintenance of this type transformer is complex than core type transformer. It repairing is complex than other.
9.        In the core type of transformer, the core is surrounded by the winding.
 In the shell type transformer, the winding is surrounding by core.
10.    Its construction: for large low voltage transformer.
Its construction: for small high voltage transformer.
11.   In larger machine, we used of core type transformer.
In small machine, we need of shell type transformer.
12.   It have two limbs

13.   We cannot provide natural cooling for this type transformer.

14.   It is used for low voltage transformer.
It have three limbs

We can provide natural cooling for this type transformer.
It is used for high voltage transformer.
15.   In this type transformer concentric cylindrical winding are used
In this type transformer sandwiched winding are used.
