Construction and application
The expansion connectors consist out of copper foils with a thickness of 0,3 mm(standard )or 0,1/0,2/0,4/0,5 on request. The contact areas are manufactured in a press-welded design.
The press-welding procedure is a special resistance welding process, which enables a welding of packages of copper foils with different strength in a defined area together. By working with this procedure it is not necessary to use any form of welding additives.
So press-welded connectors are excellent electrical conductors due to their perfect molecular connection. The contact areas can be bored, milled or bent without problem. The width of the contact areas are so selected that it is possible to install several expansion connectors in a distance of 2 mm side by side (e.g. for generator connections etc.). With drilling according to your drawings/samples or wishes.
On request it is also possible to deliver designs with coated contact areas (e.g. tinned or silvered).
