Customized copper busbars
- Connector generator & transformer to switchgear
- Rectifiers & risers
- Equipotential bonding busbars
Copper busbars 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. As part of a circuit or power grid, they provide the connection between the power source and the consumer. To achieve the lowest possible voltage drop, we use only highly conductive pure copper Cu-ETP (E-Cu) or OF-Cu for your copper bars. In addition, copper bars can be galvanically refined very well, which is why they are often used in electrical engineering for shunts or similar applications.

More InformationBusbar manufacturing with know-how
Our well-coordinated production in multi-shift operation ensures that we can react flexibly and produce your components and assembly units in the desired quality.
In addition, we are able to manufacture single pieces, prototypes, small quantities, but also large busbars with expansive dimensions and in high quantities at consistently high quality.
The real challenge is not high quality per se – but consistently high quality – contact us now!
Conductor Material & Accessories
From semi-finished to individual copper busbars
- Conductor Material Cu-ETP
- Conductor Material OF-Cu
To achieve the lowest possible voltage drop or transport loss, we use highly conductive pure copper Cu-ETP or OF-Cu for busbars. With the same cross-sectional area, copper offers the best current strength and thus also current density compared to CoppAl® and aluminum. If the smallest possible cross-section is required, copper busbars are therefore the best choice. With our wide range of semifinished products, welding techniques, finishes and insulations, we always engineer and manufacture your copper busbars to measure. For the individual design of your busbars, take advantage of our engineering know-how – we look forward to hearing from you!
Accessories for busbars
- Insulators
- Connection Clamps
- Busbar Supports
For a secure and permanent fixing of the copper busbars, we offer fixing material.
This allows you a high degree of flexibility when mounting your busbars. Our standard products are also offered in the SPS-Online-Shop.
