FERRITE TECHNOLOGY
The basis of this technology is a high quality ferrite powder.
KABELWERK EUPEN developed a special compound: a polymer material mixed with a considerable quantity of homogeneously fine ferrite powder. This compound is called EMC/COM and it can be extruded around copper conductors.
The ferrite itself is a non-conducting material, but it has a very interesting magnetic behavior. As a ferromagnetic material, it will go through hysteresis loops whenever it is under influence of an alternating magnetic field. Consecutively magnetizing and demagnetizing the material will cause considerable losses of high frequency energy. This energy is absorbed in the ferrite grains and converted into heat. This effect is more or less proportional to the field frequency
By coating conductors with a thin layer of ferrite compound, high frequencies will be strongly attenuated, because their energy will be absorbed by the ferrite powder. This applies to high frequency disturbances that are propagating on the conductor and which we don't want to disturb the environment, as well as to surrounding interferences, which we want to prevent from disturbing the signals on our cable.
The AUDUSA - Eupen GNLM cables has an additional drain wire incorporated into the cable. The drain wire(active) is in contact with the foil shield
Moreover, the ferrite layer's continuous spreading over the whole cable length makes sure that there will be no sudden changes in characteristic impedance along the cable. Otherwise, such discontinuities might cause high frequency signals to be reflected at those spots and to be sent back to the mains or to other devices.
At last, it is important to emphasize that a ferrite coated conductor will much less divert disturbances to the earth; this is an interesting feature, because disturbances that "disappear" to earth are not really gone. They will re-emerge elsewhere and cause problems.
