Variations in the flexibility of vehicle high-voltage cables

China [CN]

The available space for cable routing in vehicles deserves careful consideration. The need for tight bend radii in only one specific area of the vehicle can lead to higher overall cable flexibility requirements. If small changes in the overall design are possible, it makes sense to avoid the problem of tight bends.

It is not necessary for the cable to have the highest flexibility. The exact definition of the bending force, combined with the construction and the corresponding test equipment, allows the cable designer to create the most suitable design for the application. Especially for larger cable cross-sections, replacing highly flexible designs with more flexible or conventional structural designs will significantly reduce costs.

Of course, it is important to mention the optimization of the shielding effect of the cable: a defined shielding effect in a certain frequency range is very necessary for the development of the cable. Shielding effects without information about the frequency are not very useful, which may lead to solutions with excessive dimensions and the use of expensive combinations of shielding, which are no longer necessary from a technical point of view.

Usually, the design phase of electric vehicle cable development can give a value of the expected effect for consideration using theoretical calculations. The shielding effect of the high-voltage cable is then verified by means of tests with physical objects.
