Abstract:

Embodiments of the disclosed technology are directed to methods and/or apparatuses having a conduit with at least one length of conductive metal wire therein along with a length of non-conductive wire therein. The length of non-conductive wire comprises a heat-expandable firestop insulator material. Upon reaching a pre-defined temperature corresponding to that of a fire, the non-conductive wire expands to fill a length of the conduit. Alternatively, the firestop insulator material may be disposed in the void within the conduit that exists outside of the conductors. The expansion of the material prevents the spread of fire along the length of the conduit.
