  • What material is used for the fireproof cable tray coating

    What material is used for the fireproof cable tray coating

    Intumescent coatings are reactive fire-protection paints applied to the tray surface—often factory-applied to control thickness and quality. Under fire exposure, the coating expands to form an insulating char layer, slowing heat transfer. Most EPC specifications narrow the choice to two mainstream solutions: fire wrap systems (encapsulation) and intumescent fire-resistant coatings (reactive coatings). The cable coatings can be ablative (non-intumescent) coatings, designed for durability, provide chemical and moisture resistance, making them suitable for industrial use. There are various options and systems on the market for protecting electrical cables against the spread of fire: e. Its purpose is to ensure the integrity of electrical circuits when exposed to external hydrocarbon fires. Firestop packs should be placed in an orderly sequence.
