Copper foil for transformers is a core conductive material in the field of power transmission and electronic equipment, specifically designed to enhance the energy efficiency and reliability of transformers. The product is made of high-purity copper and combines excellent electrical performance with mechanical adaptability.
Copper foil for transformers Features
Uniform current conduction: Due to the high purity and uniform thickness of the material, the current distributes evenly on the surface of the copper foil, which can reduce the local current concentration caused by the skin effect and lower the risk of local overheating.
Strong processing adaptability: With soft texture and excellent ductility, it can be cut into any shape according to the design requirements of transformer windings, and can also be made into special-shaped structures through processes such as rolling and stamping.
Applications
Transformers: The reason why copper foil for transformers is suitable for transformers lies in the fact that its characteristics are highly consistent with the working principles, performance requirements and structural design of transformers. The core function of a transformer is “electromagnetic energy conversion and transmission”, which requires conductive materials to simultaneously meet multiple needs such as low loss, good heat dissipation, space adaptability, insulation compatibility and long-term stability. The characteristics of copper foil precisely match these requirements.
