초록

A fire protective blanket construction providing multiple time protection for application to electrical conduit and cable trays to preserve operation of electrical circuitry carried by the cables in the event of exposure to fire. Comprising the prefabricated fire resistant blanket are back-to-back blanket sections separated by a moisture impervious metal foil. Disposed within the outer of the blanket section on the exterior side of the foil is a transversely extending envelope containing a selected thickness of trihydrated alumina in powdered form. When ...
