At present, there is a great demand for cable tray in the market. When we know the manufacturer of cable trough, we can also see the specific product type. In this way, the actual choice depends on the basic situation. After knowing the product model of cable reel, we believe it will be more convenient to use.

大家都知道电缆桥架施工的防火要求很高。但是很少有人知道具体的消防要求可以表达在哪里。下面我们就以防火金属电缆盘为例，了解一下电缆盘的防火要求。

As we all know, the fire protection requirements of cable bridge construction are very high. But few people know where the specific fire requirements can be expressed. Let's take fireproof metal cable reel as an example to understand the fireproof requirements of cable reel.

防火桥就是在普通桥架表面喷涂一层防火涂料，起到防火阻燃的作用!其实桥本身不会着火，只会着火的是电缆，防火涂料发挥的防火阻燃原理。

Fire bridge is in the ordinary bridge surface spraying a layer of fire retardant coating, play the role of fire retardant! In fact, the bridge itself will not be on fire, only the cable will be on fire, fire retardant coating to play the fire retardant principle.

目前防火电缆桥架主要依据防火电缆检验标准。防火涂料的厚度应大于1毫米，耐火时间应大于30分钟，这是防火电缆防火涂料效果的一般标准。价格也有关系，包括便宜和贵，贵的效果更好。基本防火材料是钢材，防火电缆外层也有一层防火材料。确保相邻的盒子有良好的电气连接。

At present, the fire-proof cable tray is mainly based on the national fire-proof cable inspection standard. The thickness of fire retardant coating should be more than 1 mm, and the fire resistance time should be more than 30 minutes, which is the general standard of the effect of fire retardant coating for fire retardant cable. Price also has a relationship, including cheap and expensive, expensive effect is better. The basic fireproof material is steel, and the outer layer of fireproof cable also has a layer of fireproof material. Make sure the adjacent boxes have good electrical connection.

当然，为了保证较高的防火性能，除了符合桥架的防火要求和购买好的防火涂料外，电缆桥架在安装后也要进行大修，不仅是在初期施工完成后，在使用过程中也要进行大修。有关部门应定期对电缆桥架进行检查，尤其是电缆桥架的防火性能。

Of course, in order to ensure high fire performance, in addition to meeting the fire protection requirements of the cable tray and purchasing good fire retardant coating, the cable tray should also be overhauled after installation, not only after the completion of the initial construction, but also during the use process. The relevant departments should regularly check the cable tray, especially the fire performance of the cable tray.
