Electrical Power Solution

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 to the load. Both copper and aluminum windings perform the same function. For some applications, one type is preferable over the othe r. The   option you choose depends on the specific needs of your facility and your unique requirements. We’ll explain more about how aluminum and copper windings compare below. Differences Between Copper and Aluminum Windings While most low and medium voltage dry type transformers rely on aluminum windings for energy transfer, many engineers and plant operators prefer copper windings for specific applications. Here are some of the primary differences between the two types: Initial Costs At the outset, aluminum wi...
