The silver-plated copper busbar uses a cyanide/non-cyanide composite process to deposit a 3-10 µm pure silver layer. The silver layer offers high conductivity, high-temperature resistance, and extremely low contact resistance. It remains stable in high-frequency, high-current scenarios between −55 °C and 200 °C, serving applications in data center bus ducts, aerospace, military, high-end energy storage, and semiconductor equipment.

Customer Case: Using Silver-Plated Copper Busbars Saves €86, 000 in 2 Years
Location: Europe, Tier-IV Data Center Busbar Retrofit
Bare copper busbars generated heat under 10 kHz harmonic conditions, leading to a high PUE.
Replaced with 5 µm silver-plated copper busbars + phase change heat sinks.
Busbar temperature rise decreased by 4.7 °C.
Data center PUE dropped from 1.43 to 1.38.
5-year electricity savings ≈ €86, 000, payback period < 2 years.
