It brings you the fire protection problem of cable tray and the corresponding solutions. The combustible cable sheath may catch fire, so the cable fire will spread along the cable reel in the structure. This can be easily prevented by using flame retardant cable sheaths or by applying fire retardant coatings to installed cables. Thick coating or long fire damper may need to adjust the current rating of the cable, because this fire protection measure may reduce the heat dissipation of the installed cable.

定期清理房屋对安全很重要，因为电缆盘通常安装在难以触及的地方。如果不对托盘进行例行检查并保持清洁，可燃的灰尘和杂物可能会累积起来。

Regular house cleaning is important for safety because cable trays are usually installed in inaccessible places. If the tray is not routinely inspected and kept clean, combustible dust and debris may accumulate.

塑料和玻璃纤维增强塑料电缆桥架是可燃的;通过使用阻燃剂或防火材料可以减轻这种影响。

Plastic and glass fiber reinforced plastic cable trays are combustible; This effect can be mitigated by the use of flame retardants or fireproof materials.

铁质电缆桥架会随着意外火灾的热量增加而膨胀。德国Otto-Graf-Institut测试报告III.1-80999/Tei/tei证明了这一点，1984年10月23日的"关于在火灾测试中作用于电缆穿透式防火系统的机械力的补充测试"，使"软"防火装置，如那些由纤维绝缘材料和橡胶涂层制成的防火装置移位。

The iron cable tray will expand as the heat of the accidental fire increases. The Otto Graf Institut test report iii.1-80999/tei/tei of Germany proves this point. The "supplementary test on mechanical force acting on cable penetrating fire protection system in fire test" of October 23, 1984 displaces "soft" fire protection devices, such as those made of fiber insulation and rubber coating.

这也适用于任何硅酮泡沫密封，但通过使用具有足够压缩强度和厚度的防火砂浆，可以很容易地补救，如上所示。此外，一些建筑法规规定，电缆盘等渗透物的安装方式应避免其对防火墙的坍塌产生影响。

This is also applicable to any silicone foam seal, but it can be easily remedied by using fireproof mortar with sufficient compression strength and thickness, as shown above. In addition, some building regulations stipulate that the installation of penetrations such as cable trays should avoid their impact on the collapse of the firewall.
