Press Welded Flexible Copper Shunts
This type of flexible connectors are made of several copper sheets overlapping each other.
The contact resistivity in between each folio is almost zero as the contact areas are produced without using any weld filling material.
Press welded flexible copper shunts are very high electrical conductive materials due to their excellent molecular bonds. They are also ideal for coupling in areas subject to vibration and do not fracture such as rigid bars.
The welded connection ends can be drilled, cut and/or milled.
These connectors have to be used in indoor applications particularly.
Application Areas of Press Welded Flexible Copper Shunts ;
