The space available for cable routing in the vehicle deserves careful consideration. The need for tight bend radii in only one specific area of the vehicle results in increased flexibility requirements for the overall cable. Avoiding the problem of tight bends makes a lot of sense if it is possible to make small changes in the overall design.


The cable does not necessarily have to be the most flexible. The exact definition of the bending forces, combined with the structure and corresponding test equipment, enables the cable designer to create the most suitable design for the application. Especially for cables with larger cross-sections, substituting a more flexible or conventional structural design for a highly flexible design can significantly reduce costs.


Of course, the optimization of the shielding effect of the cable should be mentioned: a defined shielding effect in a certain frequency range is very necessary for the development of the cable. The shielding effect without information about the frequency is not very useful, which can lead to solutions with excessive dimensions and the use of expensive combined shielding, which is no longer necessary from a technical point of view.


Normally, theoretical calculations can be used to give an expected effect value for consideration in the development and design stage of electric vehicle cables. Then, the shielding effect of high-voltage cables is verified by means of tests in kind.
