Transformer Construction of the Core:
In general, the name associated with the transformer structure depends on how the primary and secondary windings are wound on the center laminated steel core. The two most common and basic designs of transformer structure are closed core transformer and shell core transformer.
In the "closed core" type (core type) transformer, the primary and secondary windings are wound outside the core ring. In a "shell" (shell) transformer, the primary and secondary windings pass through a steel magnetic circuit (core), which forms a shell around the windings, as shown below.
