Copper laminated flexible jumper are manufactured by stacking several foils of electrolytic copper and then applying high current under high pressure. This is a special metal diffusion whereby the metal itself melts and forms homogenous bonds thus giving a very negligible, almost nil, mill volt 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. They have a constant cross section over whole length. The current carrying capacity of solid bus bar and copper laminated jumper manufactured by this process is the same. Therefore Laminated Copper flexible Jumper are a substitute for solid bus bar.
Copper flexible Laminated jumper are Manufactured in all possible shapes & sizes as per customer’s requirements. Some of various shapes are shown in the images below.
Copper laminated flexible jumpers are manufactured by laminating high conductivity, electrolytic grade copper foils. These laminated foils are then sweated or pressure welded / fused as per customer’s requirements. Such copper jumpers carry the same current as that of Bus bars as they have a constant cross section over the whole length giving a nil mili volt drop. So these jumpers are a best substitute for solid bus bars..
Our Copper laminated flexible jumpers are widely used in following Industries: Transformers switchgear’s, power plants, Electric locomotives, furnaces, chemical plants, electricity boards & all current carrying equipment manufacturing Industries.
In Electric Locomotives, Furnaces etc..
Copper laminated flexible jumpers is used 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 jumpers have to realize movements inside machines and switchgear.Flexible Copper Laminate jumper is individually designed and manufactured keeping in view the user’s requirement and application. We also offer jumpers with contact area electro tinned, silver or gold plated to give perfect contact.
Copper laminated flexible jumpers, is available in any shape required.
