Patent on fireproof sealing structure for cable trays
A fire protection system for installation about the periphery of a cable tray consisting of parallel side rails and spaced cross members fitted between the side rails and comprising heat expanding, fire retardant composite sheet material joined together to form a protective enclosure. A fire proof cable tray constructed of assemblable units, each of which comprises a metal frame having a wire mesh covering attached thereto, an intumescent coating encapsulating the wire mesh, a layer of an inorganic, non-combustible fiber mat and a sheet of metal foil. A cable tray, phenolic resin technology, applied in the direction of pipe supports, thermal insulation, pipes/pipe joints/pipe fittings, etc. , can solve problems such as major safety accidents and failure to effectively prevent cable damage. These systems prevent fire and smoke from spreading through open cable pathways, maintaining circuit integrity and code.
