Copper Foil in Transformers
Benefit #1 of Using Copper Foil in Transformers:
Incomparable electrical conduction – This copper quality can’t be stressed enough. In fact, there is really no competition between copper’s conductivity and aluminum’s. Volume for volume the latter’s conductivity is less than 66 percent that of copper.
Benefit #2 of Using Copper Foil in Transformers:
Copper foil transformers are smaller than aluminum transformers. Copper may weigh more than aluminum, but it makes up for that heftiness with its remarkable ability to pack a lot of conductivity punch into tiny spaces. If a lightweight material is your sole determining factor, then aluminum might be a better choice. In all other cases, copper is superior.
Benefit #3 of Using Copper Foil in Transformers:
After comparing apples to apples, over time copper is very competitively priced. At first glance, aluminum looks like a more cost-effective transformer solution. And yes, its upfront price tag is lower. But as time goes by and the cost of each material is divided over its useful lifespan, copper actually wins out. Year for year, copper’s durable internal connections even give it an affordability edge. That’s because copper’s anti-corrosive properties allow it to endure for decades, in some cases up to 50 years or more. What’s more, in large transformers, the initial cash layout for copper versus aluminum is virtually the same.
Benefit #4 of Using Copper Foil in Transformers:
Copper boasts a higher reliability rating. Aluminum is prone to failure at a much higher rate than copper is.
Benefit #5 of Using Copper Foil in Transformers:
Less lamination steel is required. This is really an extension of the cost-saving benefit since steel is extremely pricey. Because copper transformers require a smaller core, they don’t necessitate as much laminating as aluminum does.
