Multilayer Copper Foils Flexible BusBars For Energy Storage Step-Up/Down Transformers (US Utility-Scale ESS)

Project BackgroundLarge container energy storage stations in Arizona, Nevada, Ohio equip 500kVA–5MVA bidirectional transformers, frequent charge-discharge current impact & cyclic temperature change.Traditional Defects of Copper Braided Shunts

1. Braided copper wire uneven contact surface, high local temperature rise under large instantaneous current
2. Strands scattered, easy wire break after thousands of thermal cycles, hidden short-circuit risk
3. Large occupied space inside transformer cabinet, not fit compact US standard energy storage container layout

Customized Flexible Copper Foil Busbar for ESS Transformer

• Ultra-thin 0.05mm copper foil stacking, 120–240 layers for high instantaneous current impact resistance
• Both ends molecular diffusion welding integrated solid terminals, flat full contact surface, stable low resistance
• Optional silver plating for high-frequency bidirectional current, lower impedance
• Short flexible segment design, save 30% cabinet internal wiring space
• Working temperature range: -60℃ ~ +150℃, adapt desert high-temperature & northern low-temperature US areas

Client FeedbackReplace braided copper shunts completely; temperature rise controlled below 40K under full load, service life extended to 15+ years, meet US utility long-term operation standards.Strength Guarantee of Xi’an Zipeng TechnologyXi’an Zipeng Technology is a professional manufacturer dedicated to the R&D, production and customization of copper foil flexible busbars and copper flexible connections.
