The advantages of using C11000 copper foil strip for transformer
winding are as follows:
1.C11000 copper foil has high tensile strength and can be stretched to a large size, with a stretching ratio of up to 30%.
2.C11000 copper foil has good corrosion resistance and weldability, and its welding position is not prone to cracks.
3.C11000 copper foil has good plasticity and can be processed into various shapes according to requirements and is easy to use.
