Bus bars

Bus bars are connecting elements used in power transmission that also guarantee a reliable electrical connection in tight spaces.

Sefag Components AG manufactures straight and bent bus bars made from copper, aluminium and brass. Depending on customer requirements, these can take the form of bus bars, complex bus bar systems or compact bus bar packages.

Bus bars are used wherever energy has to be transported in tight spaces, around corners and on multiple levels. They are used in mechanical and plant engineering, and also in energy distribution or in automotive engineering.

Up to now, we have been able to meet virtually every spatial challenge set by our customers and develop suitable solutions – even under tight schedules. As a classic solution provider, we put our experience to good use right from the initial conception phase onwards, and can combine bus bars into customised assemblies using flexible connecting elements, for example. Thanks to our far-reaching expertise and skills in production technology, we are able to implement complex power transmission solutions in even the tightest space.
