    Copper Foil Flexible Busbar Features

    Strong Flexibility & High Adaptability

    Composed of multiple layers of thin copper foil, achieving an Angle offset of ±15°. Absorbs stress from vibration and thermal expansion, ideal for EVs and photovoltaic inverters.

    Lightweight and Compact

    With a density of 8.9g/cm³, it combines high current capacity with a lightweight design. Compact size saves space in battery modules and switchgear.

    Low Inductance Anti-interference

    Special stacked structure reduces inductance to <10nH (or <5nH for high-frequency), optimizing electromagnetic compatibility and reducing switching loss.
