Generally speaking, before using cable trays, we should know the accurate selection of tray types and how to use them correctly, and understand the basic knowledge of fire-resistant cable trays.
The fire-resistant cable tray adopts a steel shell, double-layer fire-resistant cover plate, and is equipped with inorganic fire-resistant trough box inside. The average thickness of the insulation layer is 25mm, with a double-layer cover for ventilation and heat dissipation, and fireproof coating sprayed inside. When the fire-resistant cable tray encounters fire, the coating expands, blocking the heat dissipation holes and protecting the cables inside the tray. The fire resistance performance of the inorganic fireproof trough box has been tested for 60 minutes by the fixed fire resistance inspection institute, and the cable has no damage. The supporting structure is good and can effectively fix inorganic fireproof trough boxes.
Fireproof bridge is sprayed with a layer of fireproof paint on the surface of ordinary bridge to achieve the effect of fire prevention and flame retardancy! In fact, the bridge itself will not catch fire, and only the cables may catch fire. The principle of fire prevention and flame retardancy played by fireproof paint.
Let's take a look at how to correctly select fire-resistant cable trays. We have a better understanding of the differences between fire-resistant cable trays and ordinary trays, which will make it easier for people to choose fire-resistant cable trays and pneumatic ball valves.
