Round Coil vs. Rectangular Coil for Transformers
Substation transformers use round, rectangular or, less commonly, oblong core and coil assemblies. Coils facilitate the transformer’s magnetic flux flow. Coils and transformers work together to optimize performance based on design and application requirements. The transformer’s core shape determines the coil type. In other words, round iron cores must use round coils and so on. But […]

Copper vs. Aluminum Dry Type Transformer Windings
Dry type transformers typically feature either copper or aluminum windings, also known as coils. Transformer windings refer to the coils within the transformer that draw and distribute power inside the unit. There are typically two windings in a dry type transformer — one that draws power from the source and another that transfers that power […]
