Copper/aluminium laminated jumpers

Bajeria Industries offers copper/aluminium-laminated jumpers that are manufactured by stacking several foils of electrolytic copper (0.035 to 0.3 mm thick) and then applying high current under high pressure. The above said production process is a metal diffusion process whereby the metal itself melts and forms homogenous bond thus giving a very negligible, almost nil millivolt drop across the connector, thereby reducing the temperature rise and increasing the current carrying capacity of the jumper. In this process, no filler metal is used to join two layers together. The jumpers have a constant cross-section over whole length. These jumpers are a good substitute for solid busbar. It is also possible to drill, saw or mill the contact areas without any problem. These jumpers are used as expansion connectors in many applications to prevent damages by other parts of machines or switchgears and to take care of thermal and dynamic stresses caused by short circuit current in the system. The company also offers jumpers with contact area electro-tinned, silver or gold plated to give perfect contact. Application: Used as flexible expansion joints to connect busbars in switchgear industries; power plants; caustic soda and chlorine plant using mercury cell, modular cell, membrane cell, diaphragm cell, hydrochloride cell, manganese dioxide cell and cathodic protection; bus ducts; transformer; VCB; resistance welding engineering; electric locomotives; Galvano engineering and furnaces.
