前几天，后台有位粉丝吐槽：“工地上刚装的桥架才用半年就锈穿了，重新换不仅耽误工期，还多花了十几万！”其实，这种亏很多工程人都吃过。电缆桥架看着不起眼，选不对却能让你白扔几十万！今天就用直白的方式，带大家分清那些让人头疼的桥架类型，看完这篇少能省一半钱！

　　A few days ago, a fan in the backstage roast: "The bridge just installed on the construction site was rusted through after only half a year, and the replacement not only delayed the construction period, but also cost more than 100000 yuan!" In fact, many engineers have suffered from this loss. The cable tray may seem unremarkable, but choosing the wrong one can make you throw away hundreds of thousands of dollars in vain! Today, in the most straightforward way, we will guide you to distinguish the types of cable trays that cause headaches. After reading this article, you can save at least half of your money!

　　这张图里藏着一个关键规律：桥架的长相直接决定了它的 “脾气”。就像选工具得看活儿，选桥架得先搞懂每种类型的作用 。

　　There is a key pattern hidden in this picture: the appearance of the bridge directly determines its "temperament". Just like choosing a tool depends on the job, choosing a bridge requires first understanding the function of each type.

　　槽式桥架：怕干扰的线缆就得靠它

　　Slot style cable tray: cables that are afraid of interference must rely on it

　　上次去一个医院的 MRI 机房，发现所有数据线都穿在这种 “铁盒子” 里。师傅说：“这机器磁场强，不用封闭桥架，拍出来的片子全是雪花！”

　　Last time I went to the MRI room of a hospital, I found that all the data cables were threaded in this' iron box '. The master said, "This machine has a strong magnetic field, so there's no need to close the bridge. The pictures it takes are all snowflakes

　　槽式桥架就像给线缆套了个金钟罩，全封闭结构能挡住 90% 的电磁干扰和灰尘。像计算机房的网线、医院的设备控制线，用它准没错。

　　The trough bridge is like putting a golden bell cover on the cable, and the fully enclosed structure can block 90% of electromagnetic interference and dust. Like the network cable in the computer room or the equipment control cable in the hospital, using it is definitely correct.

　　但要注意：喷塑桥架的性价比，适合干燥室内，潮湿环境直接上不锈钢，贵是贵点但十年不生锈，铝合金款轻量便携，高层安装省人工。

　　However, it should be noted that the spray painted bridge has the highest cost-effectiveness and is suitable for dry indoor environments. In humid environments, stainless steel can be directly applied, which is more expensive but will not rust for ten years. The aluminum alloy version is lightweight and portable, saving labor for high-rise installation.

　　梯式桥架：能扛 “大胖子” 的硬核选手

　　Ladder style bridge: a hardcore athlete capable of carrying 'fat guys'

　　工厂车间里那些胳膊粗的电缆，普通桥架根本架不住。梯式桥架靠着 “梯子状” 结构，能轻松扛起每米 20 公斤的重载电缆，而且镂空设计散热快，夏天也不用担心电缆过热跳闸。

　　The thick cables in the factory workshop cannot be supported by ordinary cable trays. The ladder style cable tray relies on a "ladder like" structure, which can easily carry heavy cables weighing 20 kilograms per meter, and the hollow design has fast heat dissipation, so you don't have to worry about cable overheating and tripping in summer.

　　给大家举个例子：某汽车厂房用梯式桥架比普通桥架多花 5% 成本，但十年没换过，反而省了三次维修的钱。选的时候记住：热镀锌款性价比，室外用也抗造，跨度超过 6 米选大跨距梯架，少装 5 个支架

　　Let me give you an example: a car factory uses ladder style bridge frames that cost 5% more than ordinary bridge frames, but they haven't been replaced in ten years, which actually saves money on three repairs. When choosing, remember: hot-dip galvanized version is the king of cost-effectiveness, and it is also resistant to outdoor use. If the span exceeds 6 meters, choose a large-span ladder frame and install 5 fewer brackets

　　托盘式桥架：选手但别瞎用

　　Tray style bridge: versatile player, but don't use it blindly

　　办公楼的弱电井里，十有八九装的是这种浅盘状的托盘桥架。它不算全封闭但防护够日常用，底部带孔的款式还能漏水，特别适合走空调房里的线缆。不过有人把它当 “药” 就错了！上次在化工车间见到托盘桥架，三个月就被腐蚀得坑坑洼洼。记住：有腐蚀性的地方，宁愿多花钱上玻璃钢材质。组合式桥架：线路总改的工地救星智能楼宇的桥架让人头疼，今天加根网线，明天装个监控。组合式桥架就像乐高积木，能随时增减配件，后期改线路不用敲墙，光这一项就能省 2 万工时费。

　　In the weak current well of the office building, it is highly likely that this shallow tray shaped cable tray is installed. It is not fully enclosed but has sufficient protection for daily use. The style with holes at the bottom can still leak water, making it particularly suitable for cables in air-conditioned rooms. But some people mistake it for a 'panacea'! The last time I saw the tray bridge in the chemical workshop, it was corroded and pitted in three months. Remember: For corrosive areas, it is better to spend more money on fiberglass material. Combination cable tray: The smart building cable tray, the savior of the construction site for the overall line renovation, is the most headache inducing. Today, add a network cable, and tomorrow install a monitoring device. The modular bridge is like Lego bricks, with the ability to add or remove accessories at any time. In the later stage, changing the line does not require knocking on the wall, and this alone can save 20000 labor costs.

　　避坑指南：3 个选错必后悔的场景

　　Avoiding pitfalls guide: 3 scenarios where choosing the wrong one will lead to regret

　　地下室用了普通钢板桥架→半年生锈，维修花 3 万强电弱电共用槽式桥架→信号干扰导致设备宕机高温车间用封闭桥架→电缆老化速度加快 3 倍送大家一张选型对照表，保存下来下次采购直接对着勾：

　　The basement used ordinary steel plate cable trays → rusted for half a year, and the maintenance cost was 30000 yuan for strong and weak current shared trough cable trays → equipment downtime caused by signal interference → closed cable trays were used in high-temperature workshops → cable aging speed accelerated by three times. Finally, I am sending you a selection comparison table, which can be saved for the next purchase directly

　　桥架选型没那么难，记住 “看环境、算负载、留余量” 这九个字，基本不会出错。你在工地上遇到过哪些桥架坑？评论区聊聊，让更多人避避坑！

　　Bridge selection is not that difficult. Remember the nine words "look at the environment, calculate the load, and leave room", and you will not make any mistakes. What bridge pits have you encountered on construction sites? Chat in the comment section, let more people avoid pitfalls!
