Light & conductive busbars

Innovative Cuponal or CoppAl® busbars

CoppAl® or Cuponal is a bi-metal composite material used as an electrical connection in control cabinets, switchgear and distribution boards.

The machining processes such as drilling, bending, punching and sawing are comparable to those of copper bars.

Busbar manufacturing with quality & know-how

Our well-coordinated production in multi-shift operation ensures that we can react flexibly and produce your components and units in the desired quality.

In addition, we are able to produce 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!

Characteristics of CoppAl® busbars

Conductor material CoppAl® (Cuponal)

EMS Cuponal assembly

From cuponal semi-finished products to individual busbars

Our CoppAl® busbars are composite copper and aluminum busbars, also called CuAL or Cuponal. 

The copper sheath encases the aluminum core of the busbars and is inseparably bonded to it. In this way, we can optimally combine the positive properties of highly conductive copper with the low weight of aluminum. CoppAl® busbars are less expensive with the same current-carrying capacity, and are therefore a cost-saving alternative to copper busbars. For the individual design of your busbars, take advantage of our engineering know-how – we look forward to hearing from you!
