Insulated Flexible Copper Foil Busbar by China Suppliers | Quality Factory Solutions for Rail Transit
Insulated Flexible Copper Foil Busbar Core Features
The multi-layer thin copper laminated structure can be bent, twisted and folded at will, making it suitable for narrow spaces and complex paths. Reducing cable joints and wire nozzles reduces installation time by approximately 40%, meeting the demand for rapid wiring.
T2 copper base material + layered structure — current-carrying capacity is increased by more than 30% compared with cables of the same cross-section. The flat heat dissipation area is large, and the temperature rise is 15–20K lower than that of traditional cables, reducing heat loss.

Frequently Asked Questions (FAQ)
Insulated flexible copper foil busbars offer over 30% higher current-carrying capacity, 15–20K lower temperature rise, and approximately 40% faster installation compared to traditional cables of the same cross-section, thanks to their multi-layer laminated T2 copper structure.
For high-temperature environments, flame-retardant silicone insulation (60℃ ~ 200℃) or polyimide film (-196℃ ~ 260℃) are recommended. Silicone is ideal for new energy battery packs, while polyimide suits ultra-high or ultra-low temperature special equipment.
Yes. It is widely used in photovoltaic inverters, energy storage battery modules, EV charging piles, and high-voltage distribution boxes (PDU), making it an ideal solution for new energy power systems.
Absolutely. Its multi-layer thin copper laminated structure allows it to be freely bent, twisted, and folded, making it perfectly suited for narrow spaces and complex routing paths in industrial and transit applications.
The insulation layer can be customized with three material options: flame-retardant silicone (hot-press lamination), environmental protection PVC (extrusion coating), and polyimide film (hot-pressing composite), each tailored to specific temperature ranges and application scenarios.
They are widely adopted across new energy, industrial electrical equipment, rail transit, and electric power equipment industries — including applications such as distribution cabinets, transformers, UPS systems, locomotive traction systems, and generator interconnections.
