The first innovative technology in China Cable tray safety guardian Fireproof isolation products made of high-performance fireproof materials, consisting of fireproof fiber cloth A combined metal frame sprayed with fireproof paint and a flame-retardant expansion block.
Flame-retardant expansion material and flame-retardant sponge Flame-retardant expansion material is a solid flat plate, which expands when heated (temperature 160℃), Expansion ratio>500%, after preheating and expansion, its shape changes to flocculent material, and forms a completely Incombustible carbon layer. The flocculent material formed by expansion will wrap around the cable surface, fill the gap between the cable and the metal frame, and achieve flame retardant function.
Metal structural parts Use 2mm galvanized sheet Surface sprayed with fire retardant paint
Technical standards Comply with the following standard documents: GB 50217-2018 “Electric Power Engineering Cable Design Standard” GB 50872-2012 “Hydropower Engineering Design Fire Protection Code” GB 23864-2009 “Fireproof Sealing Materials”
In the early stage of fire, when the temperature rise does not reach 160℃, the fireproof cloth arranged on both sides of the fire-blocking section can prevent the flame from transferring to the other side (back of fire), thus achieving the function of blocking the initial fire.
