很多人使用电缆桥架施工以为仅仅了解它的安装相关方面的问题就行，其他的内容不是很重要，这就大错特错了，多面了解才能更好使用不出问题，下面来了解了解其他方面内容吧，

Many people use cable tray construction to think that it is only necessary to understand the problems related to its installation. Other contents are not very important. This is a big mistake. Only by understanding from many aspects can we better use the cable tray without problems. Let's learn about other aspects,

电缆桥架由钢制成，由直段、弯头、附件、桥架支吊架、梯架等组成，是用于支撑电缆的连续刚性结构体系的总称。电缆桥架通过自身的结构特性将电缆附着和支撑到建筑物（构筑物）上，或独立支撑电缆穿过隧道或洞穴、地下、空气等，主要起到支撑电缆的作用。同时，由于电缆桥架将电缆与外界隔离，对电缆也有重要的保护作用，在很大程度上便于电缆的科学布置和管理。

The cable tray is made of steel and consists of straight sections, elbows, accessories, tray supports and hangers, ladders, etc. it is the general name of the continuous rigid structural system used to support cables. Cable trays attach and support cables to buildings (structures) through their own structural characteristics, or independently support cables through tunnels or caves, underground, air, etc., mainly to support cables. At the same time, because the cable tray isolates the cable from the outside world, it also plays an important role in protecting the cable, which is convenient for the scientific layout and management of the cable to a great extent.

镀锌后粉末或油漆的复合防腐处理

Composite anti-corrosion treatment of galvanized powder or paint

表面处理过的电缆桥架的技术质量是否满足产品工艺及相关可用性的要求，可以通过涂层厚度、表面钝化、锌层附着力、锌层均匀性、外观、冲击强度、柔韧性和边角等方面来确定。覆盖率和其他检测指标。

Whether the technical quality of the surface treated cable tray meets the requirements of product process and related usability can be determined by the coating thickness, surface passivation, zinc layer adhesion, zinc layer uniformity, appearance, impact strength, flexibility, edges and corners, etc. Coverage and other indicators.

关于防腐层的环境试验，要严格区分不同类型的室内外环境。交变湿热、盐雾试验和化学腐蚀性气体试验按相应的方法标准进行。对于紫外线冷凝测试，与室内相比，紫外线主要存在于室外环境中，因此光照条件和持续时间必须满足相应要求，避免测量数据与实际数据出现较大偏差。

As for the environmental test of anti-corrosion coating, it is necessary to strictly distinguish different types of indoor and outdoor environments. Alternating damp heat, salt spray test and chemical corrosive gas test shall be carried out according to corresponding method standards. For the UV condensation test, compared with indoor, UV mainly exists in the outdoor environment, so the lighting conditions and duration must meet the corresponding requirements to avoid large deviation between the measured data and the actual data.

测试时，应根据具体的表面处理方法和使用要求选择相应的技术指标，而不是每种类型都需要选择上述所有指标。

During the test, the corresponding technical indicators shall be selected according to the specific surface treatment methods and use requirements, instead of all the above indicators for each type.

同时，为满足耐火要求，在进行防护处理时还应考虑耐火要求。如果防腐层不能满足耐火和耐火要求，还应通过涂装耐火涂料进行防火处理。

At the same time, in order to meet the fire resistance requirements, the fire resistance requirements shall also be considered during the protective treatment. If the anti-corrosion coating cannot meet the fire resistance and fire resistance requirements, it shall also be treated by coating fire-resistant coating.

根据其耐火极限时间要求的不同，相关技术规范将耐火桥的耐火极限分为三个等级：NH1、NH2和NH3。耐火性能试验应按产品相关标准进行，耐火桥表面的耐火涂层应满足涂层附着力、抗弯、抗冲击、耐水、厚度等技术质量要求和抗冻融性。

According to different requirements for fire endurance time, the fire endurance of fire-resistant bridges is divided into three grades in relevant technical specifications: nh1, NH2 and NH3. The fire resistance test shall be carried out according to relevant product standards. The fire-resistant coating on the surface of the fire-resistant bridge shall meet the technical quality requirements such as coating adhesion, bending resistance, impact resistance, water resistance, thickness and freeze-thaw resistance.

为了更真实地模拟实际使用场景，在进行耐火电缆桥架的耐火等级测试时，不仅应有至少两条直线段的耐火电缆桥架，而且应有足够多的连接器。符合实际使用条件，还必须符合测试要求。电缆的状况。

In order to more truly simulate the actual use scenario, when testing the fire resistance rating of fire-resistant cable trays, there should be not only fire-resistant cable trays with at least two straight sections, but also enough connectors. Meet the actual use conditions and test requirements. Condition of cables.

立柱支架和耐火电缆桥架依次安装在试验炉内后，试验用电缆必须按相应要求敷设在耐火电缆桥架内，装载时，装载点应避开试验电缆。

After the column support and fire-resistant cable tray are installed in the test furnace in turn, the test cable must be laid in the fire-resistant cable tray according to the corresponding requirements. During loading, the loading point should avoid the test cable.

济南电缆桥架厂家认为不同材质和结构形式的电缆桥架功能不同，对电缆的保护也是多样化的。在实际应用中，应因地制宜选择合适的电缆桥架，并按照相关规范进行检验检测，以确保产品质量。规范建设，确保相关工程质量。

Jinan cable tray manufacturers believe that cable trays of different materials and structural forms have different functions, and the protection of cables is also diversified. In practical application, appropriate cable trays shall be selected according to local conditions and inspected according to relevant specifications to ensure product quality. Standardize the construction and ensure the quality of relevant projects.
