ABSTRACT:
An engine ignition cable includes a stretching resistant central core over which an intermediate layer made of a mixture of silicone with ferric oxide powders with a ratio of 4:1 is fit. A high conductivity wire is then wrapped around the intermediate layer, preferably in a helix form, to provide a low impedance current path having an impedance of 0.8 k.OMEGA. per meter length. An insulation outer layer or sheath which may be made of silicone or rubber, is then used to enclose the cable. The use of the high conductivity wire causes a strong electro-magnetic radiation when in operation which can be counteracted, at least partially, by the magnetic field established by the intermediate layer that consists of ferric oxide powders.
