电缆桥架在现在市场中的需求很多，我们在了解电缆桥架厂家的时候也可以看看具体的产品类型有哪些？这样在实际选择的时候就应该看看基本的情况，在知道了电缆桥架产品型号之后，相信在使用的时候是会方便。

There is a lot of demand for cable trays in the current market. When we learn about cable tray manufacturers, we can also take a look at the specific product types? In practical selection, we should look at the basic situation. After knowing the model of the cable tray product, we believe it will be convenient to use.

大家都知道电缆桥架施工的防火要求是很高很高的。但是很少有人知道具体的防火要求可以表现在哪几点。下面，我们就以防火金属电缆桥架为例，来了解一下电缆桥架的防火要求。

Everyone knows that the fire prevention requirements for cable tray construction are very high. But few people know where specific fire prevention requirements can be manifested. Next, let's take fire-resistant metal cable trays as an example to understand the fire prevention requirements for 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 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.

目前防火电缆桥架主要依据对防火电缆标准进行检验标准。防火漆厚度要求于大于1mm，耐火须大于三十分钟，这是一般的防火电缆防火漆效果的标准，其中也有价钱的关系，有便宜的有贵的，贵的效果好，防火的基本是钢材，而且防火电缆外层还图有一层防火材料。还要保证相邻槽盒有着良好的电气链接。

At present, the inspection standards for fire-resistant cable trays are mainly based on the standards for fire-resistant cables. The thickness of fireproof paint is required to be greater than 1mm, and the fire resistance must be greater than thirty minutes. This is the standard for the effectiveness of fireproof cable fireproof paint, which is also related to the price. There are cheap and expensive ones, and the expensive ones have better effects. The fireproof material is basically steel, and the outer layer of fireproof cable also has a layer of fireproof material. It is also necessary to ensure good electrical connections between adjacent slot boxes.

当然，想要保证防火性能高，除了要遵守电缆桥架防火要求，购买好的防火漆之外，还应该做好电缆桥架安装之后的检修工作，初次施工完成之后的检修，还有使用过程中的检测，相关部门应该每隔一段时间就对电缆桥架进行一次检测，要对电缆桥架的防火性能进行检测。

Of course, to ensure high fire resistance, in addition to complying with the fire protection requirements of cable trays and purchasing good fireproof paint, it is also necessary to carry out maintenance work after the installation of cable trays, maintenance after the initial construction is completed, and testing during use. Relevant departments should conduct testing on cable trays every once in a while to check their fire resistance performance.
