Quiet LineTM High Voltage Distributed Loss, RF Attenuation Wire Pg. 14-15

Quiet LineTM is a continuously extruded, distributed loss, low-pass filter wire for use in high voltage applications. The stranded center conductor is surrounded with a “lossy” insulation material comprised of ferrite-powder filled silicone. This cable functions much like an inductive low-pass filter, where magnetic losses are dissipated and EMI absorbed. The ferrite in the insulation increases the cable’s inductance by concentrating the magnetic field. The increase in inductance, in turn, increases reactance which filters out high frequency noise. The cable’s attenuation characteristics increase with frequency and are directly proportional to cable length.

TRI’s Quiet LineTM is excellent for use in any high frequency, high voltage application requiring the suppression of undesired RF interference or EMI noise. In addition, use of Quiet LineTM alleviates the need for a traditional low-pass filter circuit with standalone inductors and resistors that increase the mass and take up volume in the system. These attributes make Quiet LineTM​ an ideal solution in radar, telecommunications and electronic countermeasures. Other applications include filtering capacitive or inductive coupled noise.
