FLEXICOPPER

FLEXIBLE COPPER BUSBARS

LOWER WEIGHT AND VOLUME

Thanks to the material used and the manufacturing process, the busbar can be shaped with a minimal bend radius. Compared to other cables designed for the same current load, the cross section of FLEXICOPPER is 40 % lower.


TIME-SAVING INSTALLATION, DESIGN AND EFFICIENCY

The elasticity and great formability of the busbar material allow any connection design. FLEXICOPPER maintains the desired shape, prevents unwanted deformations or memory effect. End connections can be joined only by punching. Therefore, use of cable lugs is not necessary.


SAFETY AND EMPHASIS ON RELIABLE SOLUTIONS

Designers as well as installers prefer the FLEXICOPPER busbar in view of its key qualities:
easy shaping reduces the number of interconnecting conductors,
elimination of cable lugs,
fewer connections in a project means a reduction in potential risks

CUTTING

Handled properly, the FLEXICOPPER busbar can be cut by sawing or shearing. In both cases a clean cut is achieved. If the busbar is to be bent, it is recommended to add to the required length an extra 10 mm to compensate any possible slippage of the busbar layers.



BENDING

FLEXICOPPER busbars with small and medium cross-sections can be bent. If busbars with large cross-sections are bent or twisted with a metal instrument, protect the insulation from damage. The minimum bend radius is three times the thickness of the busbar.



TWISTING

For twisting, heed the same recommendations as for bending. Ensure when rotating by 90° that the necessary length is equivalent to three times the busbar thickness.




STRIPPING

When stripping the insulation, protect the copper layer from damage and uncover only the area of the busbar that is necessary for a connection. Standard tools or only a knife can be used for stripping.




MENDING LAYERS

When bending the busbar to an acute angle, the separate layers can shift. Before the busbar is ended and a connection created, such inaccuracies must be mended by cutting.




DRILLING/PUNCHING

These operations are recommended to be done as the last part of shaping, and only after stripping of the insulation. The best connection is achieved by punching. In the case of drilling, use the adapted drilling gauge that will lead the drill tip correctly and hold the busbar. Observe the rule that the diameter of the drilled hole must not be bigger than half the busbar width.



FIXING THE CONNECTION

According to the used busbar, apply torque suitable for the used screw diameter to avoid excessive deformation and damage of the busbar.

PERMISSIBLE CURRENT

This table demonstrates the reference increase in temperature at the chosen current load for a given cross-section of a busbar. Possible increase in temperature inside the distribution board is not taken into account, so use the current coefficient for the calculation when wired in parallel.
