1. Core-type and shell-type transformers:
Core-type transformer:
- In a core-type transformer, the windings surround the core.
- The core is usually made of laminated steel sheets stacked together to provide a low reluctance path for the magnetic flux.
- The windings are wound around the core in a cylindrical shape.
- Core-type transformers are commonly used in high voltage applications.
Shell-type transformer:
- In a shell-type transformer, the core surrounds the windings.
- The windings are placed inside the core, with the core providing a magnetic path around the windings.
- The core is usually made of laminated steel sheets stacked together.
- Shell-type transformers are commonly used in low voltage applications.
2. Concentric and sandwich windings:
Concentric windings:
- In concentric windings, the windings are wound one on top of the other in a concentric manner.
- The windings are placed in layers, with each layer having a different number of turns.
- The innermost winding is usually the primary winding, followed by the secondary winding.
- Concentric windings are commonly used in distribution transformers.
Sandwich windings:
- In sandwich windings, the windings are wound side by side in a sandwich-like arrangement.
- The windings are placed next to each other, with each winding having a different number of turns.
- The windings are separated by insulation material to prevent short circuits.
- Sandwich windings are commonly used in power transformers.

Core-type Transformers
In a core-type transformer, the core surrounds the windings. This type of transformer is more efficient than a shell-type transformer, but it is also more expensive to manufacture.

Shell-type Transformers
In a shell-type transformer, the windings surround the core. This type of transformer is less efficient than a core-type transformer, but it is also less expensive to manufacture.

Concentric Windings
Concentric windings are wound around a central core. This type of winding is used in low-voltage transformers.

Sandwich Windings
Sandwich windings are made up of two or more layers of windings that are separated by a layer of insulation. This type of winding is used in high-voltage transformers.
