Single UPS unit carries a heavy current ranging from 1000A to 5000A. Traditional rigid copper busbars are bulky and difficult to install. Besides, thermal expansion and contraction will generate mechanical stress and deform the cabinet, which seriously undermines the stability of precision power distribution in data centers.

Xi'an Zipeng Technology provides tailor-made extra-long copper foil flexible connections to link UPS units with main busbars of distribution cabinets, perfectly targeting high-current connection demands.

custom‑engineered flexible connections rated for ≥42kV/1min withstand voltage, designed specifically for high‑voltage transition applications.

When rigid copper busbars are used to connect circuit breakers, bolts tend to loosen due to closing vibration, thermal expansion and contraction, as well as accumulated installation errors. This leads to increased contact resistance and excessive temperature rise up to over 60K. In severe cases, contacts will be burned out and power outages may occur.

Integrated fully insulated flexible laminated copper busbars replace split rigid copper bars. Single-piece flexible connectors sized 150×12mm remove all intermediate joints, covered with UL-listed flame-retardant epoxy insulation.

16000kVA high-capacity oil-immersed rectifier transformer with ultra-high DC output current on low voltage side; operating under extreme ambient temperature ranging from -38℃ to +58℃ in desert conditions.

• Copper foil flexible busbar 
• Excellent flexibility from laminated 0.05~0.1mm ETP copper sheets to absorb thermal expansion and mechanical vibration effectively;
• Diffusion-welded terminals with tin/silver plating minimize contact resistance, limiting temperature rise below 12K and reducing transformer power loss;
• Bendable design fits compact European cabinet layout, cutting on-site installation time by 50%;
• Full epoxy/silicone insulation provides moisture, dust and corrosion resistance for both indoor substations and outdoor packaged transformers.

With the rapid development of new energy battery power plants, energy storage stations, and electric vehicles, battery copper foil soft connection has become an indispensable core component for the flexible current conduction within the battery PACK. Reasonable selection directly determines the stability of equipment current carrying capacity, temperature rise control, shock resistance lifespan, and usage safety. This article explains the standard selection method for battery copper foil soft connection from six dimensions: current, material, structure, process, environment, and installation.
