ABSTRACT:
An ignition coaxial cable includes at least a braided layer of copper wires surrounding a central or inner conductor existing at a longitudinal center of the coaxial cable for shielding and grounding the interference caused by the high voltage carried by the cable, and an interference eliminating circuit having an inductor parallelly connected with a high-impedance resistor and connected in series with a low-impedance resistor to prevent the acute wave forms and to inhibit the surge waves caused by the high-tension voltage pulses delivered from the distributor to the plug, thereby eliminating the interference or electromagnetic interference caused by the high-tension cable and the plug of the car.
