Amiable Impex, AI Earthing are Manufacturer, Exporter and Suppliers of Copper Jumpers, Copper Flexible Connector, Copper Laminated Flexible Connector, Copper Laminated Flexible Shunt, Copper Laminated Flexible Jumper.
We Manufacturer Best quality of Copper Jumpers, Copper Flexible Connector, Copper Laminated Flexible Connector, Copper Laminated Flexible Shunt, Copper Laminated Flexible Jumper. that are manufactured by stacking several foils of electrolytic copper and then applying high current under high pressure. These types of Copper Laminated Flexible Connectors, Jumper and Shunt are commonly used as the flexible expansion joints for connecting the bus bars in different applications.
Copper Laminated Flexible Connections/ Jumper/ Shunt are produced from high conductivity electrolytic grade copper foils / sheets.
The method used is described below:
Press Welding
In Press welding, individual Copper strips are fused (one homogeneous mass) together by applying direct current and pressure without the use of any foreign material. It results in producing a solid palm with properties of a plain bus bar of the same cross section. This method assures minimum resistance thus increasing the product life & reduction in downtime. Welding provides the best mechanical & electrical properties at high temperatures. These are available in all sizes covering the desired cross section area. Slotted holes can be provided up on request.
Copper laminated Flexible Connectors consist of several stacked strips with riveted or welded contact areas. They have a constant cross-section over the whole length. Bus bars and Copper laminated Flexible Connectors with the same cross-section can be loaded with the same current. A part of Copper Laminated Flexible Connectors are utilized as flexible expansion connectors in order to connect bus bars of switch gears, transformers, generators, etc. Thanks to their elasticity, thermal expansion of bus bars is being compensated.
Most of the parts are being used as expansion connectors to prevent damages by vibration caused by switch gear operations. Another part is utilised as flexible components inside parts of machines (Like welding machines or switch gears). These kind of connectors have to realise movement inside machines and switch gears. To manufacture suitable connectors for the variable applications we have different method of production.
We are able to Manufacture Copper Jumpers, Copper Flexible Connector, Copper Laminated Flexible Connector, Copper Laminated Flexible Shunt, Copper Laminated Flexible Jumper in
- Press Riveted Design
- Fusion Welded or Soldered Design
- Press Welded Design

This is a special metal diffusion whereby the metal itself melts and forms homogenous bonds 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 Copper Jumper. In this process, no filler metal is used to join two layers together. They have a constant cross section over whole length. The current carrying capacity of solid busbar and copper laminated Flexible jumper manufactured by this process is the same. Therefore these Copper jumpers are a substitute for solid busbar. It is also possible to drill, saw, braze, mill & weld the contact areas without any problem. These types of Copper Flexible Laminated Connectors are used as flexible expansion joints in order to connect busbars in Switchgear industries, Power plants, Caustic Soda, Chlorine plant using mercury Cell, Modular Cell , Membrane Cell, Diaphragm CEll, Hydrochloride Cell, Manganese Diodide Cell and Cathodic Protection, Bus Ducts, Transformer, V.C.B., Resistance welding engineering, Electric Locomotives, Galvano Engineering, Furnaces etc. as expansion connectors 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. These Copper Laminated Flexible Jumpers have to realize movements inside machines and switchgear. These Copper jumpers are individually designed and manufactured keeping in view the user’s requirement and application.
