Movable Expansion Busbars

Flexible Expansion Busbars are used to compensate for expansion and vibration within busbar connections. They are also installed as flexible power transmission elements in machines and switchgear.

Consisting of copper lamellas with a thickness of 0.2 mm, they are pressure-welded at the ends. Aluminium strips consist of 0.3 mm thick lamellas and are welded to solid connections using a protective gas.

EMS manufactures customized connection technology and flexible Expansion Busbars in various dimensions.

Conductor material laminated expansion connectors

Flexible laminated expansion conductors made of copper or aluminium

Laminated expansion connectors depend on the required current values, mainly copper and aluminum lamellas are used and combinations of both materials are also possible.

Copper laminated expansion connectors made of Cu-HCP with press welded connections of the same material
Aluminium laminated expansion connectors made of EN AW-1050 with MIG-welded connections of EN AW-6060

Connectors laminated expansion conductors

EMS is highly experienced in the production of highly developed connectors made of different materials:

Press welded connections have an excellent conductivity due to a perfect molecular connection. The connection surfaces can be drilled, milled and bent.
Welded under protective gas, connections are melted locally by means of an electrically generated arc. The protective gas prevents the metal to melt due to oxidizing.
Soldering the connections enables very complicated constructions to be implemented. Depending on application, different brazing alloys and different processes are available.
