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.
The EMS Group is certified according to
DIN EN ISO 9001:2015
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!
Conductor material CoppAl® (Cuponal)
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!
