ABSTRACT:
The present invention features a new shield material useful in the fabrication of shielded wire or cable articles. The conductive core of the wire and cable is layered with a shielding wrapping tape, foil or film. A shielding insulation compound can also be extruded over the conductive wire or cable core. Wire and cable articles containing the new shield material have an extended interference frequency attenuation range resulting from the improved shield layer. The shield material contains shaped ferrite particles dispersed within a polymeric binder, such as a fluorocarbon polymer. The shaped particles are generally spherical.
