Comparison between Core-type Transformer and Shell-type Transformer

Core-type Transformer and Shell-type Transformer

Comparison between Core-type Transformer and Shell-type Transformer can be in the factors like a count of magnetic frame limbs, magnetic circuits, winding encircles in the core, repair difficulty, cooling and preferred voltage transformer type.

S.no
Core-type Transformer
Shell-type Transformer
1 The core-type transformer consists of a magnetic frame with two limbs. The shell-type transformer consists of a magnetic frame with three limbs.
2 The core-type transformer has a single magnetic circuit. The shell-type transformer has two magnetic circuits.
3 The winding encircles the core. The core encircles most parts of the winding.
4 It consists of cylindrical windings. It consists of sandwich-type windings.
5 It is easy to repair. It is not easy to repair.
6 It provides better cooling since windings are uniformly distributed on two limbs. It does not provide effective cooling as the windings are surrounded by the core.
7 The core-type transformer is preferred for low-voltage transformers. The shell-type transformer is preferred for high-voltage transformers.
