Core Type Transformer: What is it? | Electrical4U· There are two main types of transformers which can be categorized by the shape of the magnetic core. These are core type transformers, and shell-type transformers (and less commonly, air core transformers).We shall discuss here the core type transformer.. The core of single phase core type transformer is a single window core. This means there are two limbs as shown in the figure below.
