Ultraflexx busbars are highly flexible connectors, produced of copper braided flexibles. The ends are presswelded. Contrary to the generally applied pressed connector technology, by this procedure, the whole terminal is presswelded over the whole surface and can be treated like a massive end.

  • no additional contact resistance - therefore smaller power losses

  • no corrosion, therefore no increase of the contact resistance by time

  • Ultraflexx busbars are highly flexible connectors, fast and easy to install.
