Aluminium foil/strip for transformers winding, also called aluminum transformer foil/strips, which are mainly used in the dry type and oil-immersed transformers manufacturing industries.
With high conductivity, good corrosion resistance and beautiful appearance, transformer aluminum strips are essential materials in the process of producing transformers.
