电缆桥架是电气工程 “布线神器”，但很多人被 “槽式、托盘式、梯式” 绕晕，甚买错型号返工！今天用大白话拆解核心知识，步骤清晰，看完就能选对、用对！

　　Cable tray is the "wiring artifact" of electrical engineering, but many people are confused by "trough, tray, ladder" and even buy the wrong model for rework! Today, I will break down the core knowledge in plain language, with clear steps, and after reading it, you can choose and use it correctly!

　　一句话搞懂：电缆桥架是什么？

　　One sentence to understand: What is a cable tray?

　　简单说，电缆桥架就是 “电缆的专属轨道”—— 由托盘 / 梯架 / 槽盒、支吊架、连接件、附件组成，能保护电缆、方便布线检修，还能帮电缆散热，工业厂房、写字楼、市政工程都在用！

　　Simply put, cable tray is the "exclusive track for cables" - composed of trays/ladders/trays, supports and hangers, connectors, and accessories, which can protect cables, facilitate wiring and maintenance, and help dissipate heat. It is used in industrial plants, office buildings, and municipal engineering!

　　3 类核心结构：一看就懂，不会选错

　　3 types of core structures: easy to understand at a glance, won't choose the wrong one

　　槽式电缆桥架：像个 “封闭的 U 形槽”，带盖板，防尘防潮防干扰，专门放通信、控制电缆（比如机房里的网线、设备控制线）；

　　Slot type cable tray: like a "closed U-shaped slot" with a cover plate, dust-proof, moisture-proof, and anti-interference, specially designed to accommodate communication and control cables (such as network cables and equipment control lines in the computer room);

　　托盘式电缆桥架：半封闭设计，底部有孔，既能挡点灰，又能散热，家里装修、照明的动力电缆选它准没错；

　　Tray type cable tray: semi enclosed design with holes at the bottom, which can block some dust and dissipate heat. It is the right choice for power cables for home decoration and mall lighting;

　　梯式电缆桥架：开放式的 “梯子”，散热，能放很多大直径电力电缆（比如工厂里的 10kV 高压电缆），就是有点容易积灰（高空布线不用怕）。

　　Ladder type cable tray: An open "ladder" with the best heat dissipation can accommodate many large-diameter power cables (such as 10kV high-voltage cables in factories), but it is a bit prone to dust accumulation (there is no need to worry about high-altitude wiring).

　　4 大核心部件：少了它们桥架用不了

　　4 core components: Without them, the bridge cannot be used

　　主体：直线段（走直线）、弯通（转方向）、三通 / 四通（分岔路），常规 2-3 米长，不够长可以拼接；

　　Main body: straight section (walking in a straight line), bend (turning direction), tee/four-way (branching road), usually 2-3 meters long, can be spliced if not long enough;

　　支吊架：相当于 “支架腿”，托着桥架不塌，1.5-2 米装一个就行；

　　Support and hanger: equivalent to "support legs", it supports the bridge without collapsing, and can be installed every 1.5-2 meters;

　　连接件：连接板 + 螺栓，把各部件拼起来，拧牢固别松动；

　　Connecting components: connecting plate+bolt, assemble all components together, tighten firmly without loosening;

　　附件：盖板（防脏）、隔板（分电缆）、接地夹（防触电），都是 “保命又好用” 的配件。

　　Accessories: Cover plate (dirt proof), partition (cable separation), grounding clip (electric shock proof), are all "life-saving and easy-to-use" accessories.

　　新手选型 1 个技巧：不会错！

　　One tip for novice selection: It won't be wrong!

　　先想 2 个问题：① 你要放什么电缆？② 环境脏不脏、潮不潮？

　　First, let me ask you two questions: ① What cable do you want to put in? ② Is the environment dirty or damp?

　　通信 / 控制电缆 + 潮湿环境→槽式；

　　Communication/control cables+humid environment → trough type;

　　动力 / 照明电缆 + 常规环境→托盘式；

　　Power/lighting cables+regular environment → tray type;

　　大直径电缆 + 工业厂房→梯式。

　　Large diameter cable+industrial plant → ladder type.

　　实用提醒：

　　Practical reminder:

　　买桥架时，一定要说清 “电缆类型 + 环境”，比如 “我要放通信电缆，在地下车库用”，商家直接给你槽式带盖板的，不会出错！

　　When buying a cable tray, be sure to clearly state the "cable type+environment", such as "I want to put communication cables for use in an underground garage". The merchant will directly recommend a slot type with a cover plate for you, without making any mistakes!
