Abstract
A self-suppression wire for a detonation circuit of an airbag includes a stranded copper conductor, a layer of ferrite filled polymer extruded around the stranded copper conductor, and an insulation layer which is preferably annularly extruded around and directly over the ferrite filled polymer, where one end of the self suppression wire is connected to an ignition signal generator, and the other end is connected to a detonator, the detonation of which results in inflation of an airbag. A self-suppression wire combination and cable also employ the above configuration.
