Abstract
A shielded cable is disclosed having metal coated aramid fibers as the shielding.
Claims3
A cable article having shielding against EMI and RFI, comprising:
- a conductive core member;
- at least one layer of insulation disposed over said conductive core member;
- a layer of shield material consisting essentially of metallic coated aramid fibers are braided into a mesh to provide a protective shield layer disposed over the insulated conductive core member, said braided mesh forming a shield layer that exceeds 96% coverage of said at least one layer of insulation and providing shielding effectiveness of 25-40 decibels across a frequency range of 10 to 1000 MHz.
