Windings are wrapped around the center leg of a laminated core. Generally used in single phase transformers
Core Type
Windings are wrapped around two sides of a laminated square coreUsed in high output transformers

Construction of transformer from stampmpings

Sectional View Of Transformer
Inter leaving of LV and HV windings for better magnetic coupling
High voltage conductors are smaller cross section conductors than the low voltage coil(LV) winding is easiest to
insulate, it is placed nearest to the core.

Berry type transformer
More parallel paths for flux. Cylindrical windings are used.
Advantages Of Transformer

Voltage can be easily changed,it is a Static device, no wear and tear
Most efficient electrical machine, very less maintenance required
