How many types of overhead transformers are there?

Explanation:
Two main construction styles define overhead transformers: core-type and shell-type. The distinction is in how the magnetic core and windings are arranged and how flux travels. In a core-type transformer, the core forms a simple rectangular frame with windings on the limbs; most of the magnetic flux goes through the core, making the design straightforward and robust for many distribution applications mounted overhead. In a shell-type transformer, the winding sits inside a core that surrounds the central limb, concentrating flux and providing stronger mechanical rigidity and better short-circuit performance. These two configurations are the standard, so there are two types.
