防火桥架的与桥架的规格有直接关系，桥架的规格越大桥架的越高。例如桥架的宽度相同，桥架高度越高越高，桥架的高度相同，桥架的宽度越宽，桥架的也越高。

The price of fireproof cable trays is directly related to the specifications of the cable trays, and the higher the specifications of the cable trays, the higher the price of the bridge frame. For example, if the width of the bridge is the same, the higher the height of the bridge, the higher the price. If the height of the bridge is the same, the wider the width of the bridge, and the higher the price of the bridge.

防火桥架弯通配件中的终端封头和伸缩节也需要单独提料。伸缩节默认无盖，如需要增加伸缩节盖板需备注说明。有问题可以直接咨询防火桥架厂家，会有人员接听指导。

The terminal heads and expansion joints in the bending fittings of the fireproof bridge also need to be separately extracted. The expansion joint has no cover by default. If an expansion joint cover needs to be added, please note and explain. If you have any questions, you can directly consult the manufacturer of the fireproof cable tray, and there will be professional personnel to answer and guide you.

防火桥架的常用大规格有600*150mm、600*200mm、800*150mm、800*200mm、1000*200mm等。防火桥架敷设之前要按照项目方提供的电气施工图进行现场测量，尽量采用的标准产品和工厂订制件。

The commonly used large specifications of fire resistant cable trays include 600 * 150mm, 600 * 200mm, 800 * 150mm, 800 * 200mm, 1000 * 200mm, etc. Before laying the fireproof bridge, on-site measurements should be carried out according to the electrical construction drawings provided by the project party, and standard products and factory ordered parts should be used as much as possible.

防火桥架敷设的托盘和梯架应该合理分段，避免两节连接处跨墙或走楼洞。

The trays and ladders laid on fire resistant cable trays should be reasonably segmented to avoid crossing walls or building openings at the connection between the two sections.

此外山东电缆桥架厂家提醒您，防火桥架不同耐火等级代表着起火后桥架内的电缆维持正常工作时间的长度，按照桥架标准分为三个等级，NI等级代表时间大于等于60分钟，NII等级代表时间大于等于45分钟，NIII等级代表时间大于等于30分钟，用户可以项目消防桥架防火性能要求来选择对应耐火等级。

In addition, Shandong cable tray manufacturers remind you that different fire resistance ratings of fire resistant trays represent the length of normal working time for cables inside the tray after a fire. According to the tray standards, they are divided into three levels: NI level represents time greater than or equal to 60 minutes, NII level represents time greater than or equal to 45 minutes, and NIII level represents time greater than or equal to 30 minutes. Users can choose the corresponding fire resistance rating according to the fire performance requirements of the project's fire resistant tray.

防火桥架的重量决定因素包括桥架的宽度、高度、厚度和密度，宽度越宽重量越大，例如200*50mm比100*50的桥架要重，高度越高重量越沉，例如100*100mm比100*50mm的桥架要沉，厚度越厚重量越大，例如200*100*1.2mm比200*100*1.0mm的桥架重量大。还有怎样的疑惑或者需求，就来我们网站http://www.sdhangfeng.com咨询吧！

The weight determining factors of a fireproof bridge include the width, height, thickness, and density of the bridge. The wider the width, the heavier the weight. For example, a 200 * 50mm bridge is heavier than a 100 * 50 bridge, and the higher the height, the heavier the weight. For example, a 100 * 100mm bridge is heavier than a 100 * 50mm bridge, and the thicker the thickness, the heavier the weight. For example, a 200 * 100 * 1.2mm bridge is heavier than a 200 * 100 * 1.0mm bridge. If you have any further doubts or needs, please come to our website http://www.sdhangfeng.com Consult!
