Transformer Winding Copper Strips
Transformer winding copper strips, also called copper strips foils for transformer winding, are mainly used in the transformers manufacturing industries.
The commonly used copper grades are ETP Grade (Electrolytic Tough Pitch), C11000, UNS C10200 TU1, temper O state.
The thickness of copper strip is usually between 0.01mm-3.0mm.
The transformer winding copper strip can be customized according to customer requirements of different widths and thicknesses.

What are the transformers copper strips?
Copper strip is made by rolling copper to a very thin thickness (between 0.01mm and 3.0mm) and then cold-rolling or hot rolling depending on the required thickness. This can be followed by annealing (for even greater flexibility) and further processed into strips or laminated sheets with insulation materials.
The majority of copper foil is used in dry-type transformers and small transformers, where they are wound together with insulating materials.
What are the advantages of using copper strips for transformers?
As a result of the low percentage of impurities, copper strip for transformer winding with over 99.8% IACS high electrical conductivity, durability and malleability is widely used in transformers, reactors, filters and mutual inductors.
There is no burr on the edge of copper strip for transformer winding. Surface atomization treatment makes the surface of copper strip foil to get to the brighter and cleaner level.
How to buy copper strips for transformers?
Buyers should find and purchase their transformer copper strips needs through sourcing from manufacturers and distributors.
To buy copper strips, the buyer should consider:
- The supplier’s experience in the industry.
- The quality of goods manufactured by the supplier.
- The financial stability of the supplier.
- The supplier’s delivery system.
To get a quote for copper strips you need to know below information:
- Quantity (Kgs/Tons)
- Size (Thickness x Width x Coil)
- Material Grade (C11000, etc)
- Edge (Deburred/Round)
- Coil ID (200mm/300mm/400mm/500mm)
How about transformer copper strips production process?
Copper foils strips for transformers winding production process is to use the continuous casting and rolling method to produce long copper strips.
The general production process of copper strips is:
1.Copper ingot cast into semi-finished product;
2.The semi-finished product is rolled into a finished product;
3.The finished product is annealed, and then annealed, bundled according to specifications, and aged;
4.Use appropriate packaging for storage or transportation
What are transformer copper strips packaging?
- Standard export wooden pallet or wooden case. Also we can meet special requirements from our customers.
- Deliver copper strip in coil, hard paper core inside.
- Eye to wall and eye to sky are both available.
- Grate car is taken to avoid any damage which might be caused during storage or transportation.
- In addition, clear labels are tagged on the outside of the packages for easy identification of the copper strip for transformer winding.
