Flexible Copper Busbars

Flexible Copper Busbars for High-Current Power Connections

Laminated flexible copper busbars for AI racks, UPS, battery systems and PDU. Manufactured to your drawing with custom dimensions, plating and end terminations.

Flexible Busbar Types

Laminated Flexible Busbars

Multiple thin copper foil layers bonded together. Low inductance, flexible and vibration-resistant.

Copper Foil Busbars

Single or multi-layer copper foil for compact, flexible power connections in tight spaces.

Braided Copper Connectors

Woven copper braid for high-flexibility, high-current connections with excellent vibration tolerance.

Custom Flexible Assemblies

Flexible busbars with custom end terminations, hole patterns and plating to your drawing.

Why Flexible Busbars?

Flexible busbars absorb vibration, compensate for misalignment and allow movement between connected components. They have lower inductance than round cables and are preferred in high-current power electronics and battery systems.

Frequently Asked Questions

What is a flexible copper busbar?

A flexible copper busbar is made from multiple thin copper foil layers bonded together. The layered construction allows the busbar to flex and absorb vibration while maintaining high current-carrying capacity.

What is the difference between a flexible busbar and a cable?

Flexible busbars use flat copper foil layers and have lower inductance than round cables. They are preferred in power electronics and high-current applications where inductance matters and where a flat, compact connection is needed.

Can you manufacture to my drawing?

Yes. Send your DWG, DXF, STEP, PDF or dimensioned sketch. We will review the specification and provide a sample quotation.

What plating options are available?

Tin plating (matte and bright), silver plating and bare copper. Plating thickness to specification.
