ABSTRACT:
An insulated cable has a hermetically enclosed sheath. Between the sheath and the insulation of the cable is a filler of a thermoplastic material. When the cable is heated (e.g. a localized fire) gases and acids that are given off by the insulation are absorbed by the filler which also expands resulting in a structural blockage to the longitudinal flow of the acids and gases.
