Buy copper busbars fast

Copper busbars from buzzbar – our one-offs, prototypes or small quantities convince through consistent quality.

We stand for efficient production of busbars

Do you need a copper busbar prototype or a small series of copper busbars quickly?

Whether for switchgear, control cabinets or other applications, we manufacture and supply copper busbars according to your design. 

buzzbar copper busbars are electrical conductors that transmit signals or high frequencies. As part of a circuit or power network, they provide the connection between the power source and the consumer. To achieve the lowest possible voltage drop, we only use highly conductive pure copper Cu-ETP for your copper busbars. With our buzzbar manufacturing standards for punching, bending, sawing and deburring, we ensure compliance with standards and tolerances.

Possible applications

buzzbar copper bars are used, among other things, as electrical connection elements in high-current technology, high-voltage technology, the electrical industry, the chemical industry, energy supply, renewable energies, storage technology, mechanical engineering and e-mobility.


In addition, copper busbars can be galvanically refined very well, which is why they are often used in electrical engineering for shunts or similar.

Our copper busbars for your switch gear

Copper busbars or busbars serve as a central distributor in your switchgear. In order to achieve the lowest possible voltage drop or transport loss, conductive materials such as copper are used for busbars. With the same cross-sectional area, copper offers the best current strength and thus also current density compared to CoppAl® and aluminium.

If the smallest possible cross-section is required, copper is therefore the best choice. With our large semi-finished product range of standard dimensions, you can also order individual pieces or small quantities from buzzbar.
