Copper Foils For Transformer Windings

copper strip for transformer windings

Copper 99.9%
high conductivity
width tolerance is ± 0.2mm
The thickness control can be controlled below ± 5 microns
Used for distribution system, low voltage transformer windings.

Copper Foils For Transformer Winding is widely sold in the world with high performance, also called transformer Copper Coils. The commonly used copper grades are ETP Grade (Electrolytic Tough Pitch), C11000, UNS C10200 TU1, temper O or H state.
