Measured surface transfer impedance of braided cable shields made from metal clad aramid yarn blended with metal wires

The surface transfer impedance of six braided cable shields made from nickel plated copper wires, metal clad aramid yarn or a blend of metal clad aramid yarn and nickel plated copper wires. At high frequencies, these measurements showed that the metal clad aramid braid is equivalent to nickel coated copper braid. At low frequencies, the addition of nickel coated copper wire significantly improved the shielding performance. Finally, the Aracon(R) blended braid can be used on both metal and composite connector fittings.
