Main features of flexible insulated busbars Easy assembly: it could be easily bended and fixed with handsor easy tools. Possibility of reducing sizes of the equipment: Due to favorable thermal radi ation properti es, the flexible insul ated busbars canhandl eheavier current loads than solid busbars of the same cross-section. Due to good insulating performance of the PVC, i t could be possible to reduce the di stancesbetween di fferent flexible insulated busbars and between the flexible insul ated busbars andearth. The bendi ng-radius could be smaller than that of normal cable or solid copper bars, so thatthe connections could be more simple and short, and visually it could have better effect. Lower temperature riseon the flexi ble insul ated busbars than onnormal copper bars. High flexibility: no problem wi th vi brationsor thermal expansions. Application of flexible insulated busbars The flexi bil ity of the bars makes i t possible to install them into di fficul t equipment or small placesvery easily. They wil l be particul arly well used as connectors i n switchgears and between transformers, switching devi ces and prefabricated power networks.

We offer aluminium laminated flexible shunts. Copper laminated flexible jumpers 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, 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. They have a constant cross section over whole length. The current carrying capacity of solid busbar and copper laminated jumper manufactured by this process is the same. Therefore these 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 flexible 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 jumpers have to realize movements inside machines and switchgear. These jumpers are individually designed and manufactured keeping in view the users requirement and application. We also offer jumpers with contact area electro tinned, silver or gold plated to give perfect contact.
