A failure-resistant electrical ignition system cable (10) comprises first and second terminal contacts (28 and 30) for contacting a source of ignition pulses and contacting the predetermined destination of these pulses, respectively; a plurality of flexible ignition conductors (16 and 18) connected between the first and second terminal contacts, each of the ignition conductors being capable of electrically communicating the ignition pulses between the terminal contacts, each of the ignition conductors comprising in electrically-inert center (20), an elongated conductive wire (22) spirally and interstitially wound around the center for substantially the full length thereof, each of the ignition conductors then being twisted about each other so as to provide repeated electrical contacts of the conductive wire of each whereby electrical continuity between the terminal contacts may be maintained despite the occurrence of one or more electrical discontinuities the outer exposed surfaces of the twisted ignition conductors being electrically insulated by a flexible insulating medium (26). The cable may optionnally include a concentric reenforcing braid (32) intermediate the ignition conductors and the outer surface of the ignition system cable.
