COPPER FOIL FLEXIBLE CONNECTION

"Copper foil flexible connections are flexible conductive components used in electrical equipment, typically made by stacking or welding multiple layers of high-purity electrolytic copper foil. They feature excellent conductivity, flexibility, and fatigue resistance. High conductivity: copper's conductivity is second only to silver, suitable for high-current transmission. Good flexibility: they can be bent and twisted, adapting to equipment vibration or displacement and avoiding stress fractures from rigid connections. Low resistance and low heat generation: they reduce energy loss and improve system efficiency. Corrosion resistance: surfaces can be tin-plated, nickel-plated, or silver-plated for enhanced oxidation resistance. Easy installation: they are fixed by bolting, welding, or crimping, offering flexible installation options.

COPPER BRAIDED WIRE

Copper braided wire is a flexible conductive material made by weaving multiple strands of fine copper wires. It boasts excellent electrical conductivity, flexibility, and corrosion resistance, making it widely used in electrical connections, grounding, electromagnetic shielding, and other applications. High conductivity: Made from pure copper—typically T2 red copper or oxygen-free copper—with a conductivity exceeding 98%. Good flexibility: Its braided structure allows it to bend and twist, adapting to complex installation environments. Heat and corrosion resistance: It can be tinned, silver‑plated, or coated with other protective layers to enhance oxidation resistance and corrosion durability. Strong fatigue resistance: It remains durable under vibration or frequent movement, making it ideal for applications such as mechanical equipment and automotive wiring harnesses.

COPPER-ALUMINUM BUSBAR CONNECTION STRIP

Aluminum busbars and hard copper busbars for new‑energy batteries, including positive and negative current collectors, etc. Electrical Conductivity: Copper boasts an electrical conductivity of up to 97% IACS (International Annealed Copper Standard), making it well suited for high‑current applications. Mechanical Properties: High tensile strength—hard‑tempered copper busbars can reach 300–400 MPa—and excellent wear resistance; however, they exhibit poor bendability and must be annealed to soften before bending. Corrosion Resistance: Bare copper is prone to oxidation, so its surface is often coated with tin, nickel, or silver to enhance corrosion protection. Temperature Range: Typically operates between –40°C and 105°C; at elevated temperatures, special treatment may be required.
