Insulated Copper Flex Bars.
A Cu-flex copper busbar is made of copper wires that are woven to a flexible busbar. Nexim's patented technique forges the ends of the busbar to a solid unit and thus obtaining a contact surface that makes it possible to produce maintenance-free connections.
Insulated flexible copper bars are mainly utilized for providing the power connections between busbars and the disconnection devices within an electrical panel.
The insulated layered copper allows the flexible copper bar to be easily formed to provide a customized solution.
Advantages
Easy to install
• Compact version.
• High level of flexibility enabling easy manipulation of the busbar.
• Reduced installation time with the elimination of terminal lugs and their crimping.
Increased safety by the elimination of crimped connections
• Better behavior under short-circuit conditions.
• Decreased number of heating points.
• More reliable connections.
