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.
|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.|
