防火桥架的作用是什么？

What is the function of fire resistant cable trays?

　　防火桥架是在普通桥架表面喷涂一层防火漆，以起到防火阻燃的作用！其实桥架本身并不会着火，着火的只可能是电缆，防火漆所起到的防火阻燃原理

Fireproof cable tray is sprayed with a layer of fireproof paint on the surface of ordinary cable tray to play a role in fire prevention and flame retardancy! In fact, the bridge itself does not catch fire. What catches fire can only be the cables, and the fire retardant principle played by the fireproof paint

　　防火桥架的防护厚度按 / T 10216一2000《电控配电用电缆桥架》表10要求，电镀大于12μm，热镀大于65μm ,喷塑大于50μm，防火大于500μm ,可以用测厚仪测出来。

The protective thickness of the fireproof cable tray shall comply with the requirements of Table 10 of /T 10216-2000 "Cable trays for electrical control and distribution", and the electroplating shall be greater than 12 μ m. Hot plating greater than 65 μ M, spray molding greater than 50 μ m. Fire prevention greater than 500 μ M can be measured using a thickness gauge.
