I wonder if friends have noticed that when we buy cable trays, we often see English letters on the inside of the tray. What do these letters mean? Please listen to the cable tray manufacturer to interpret for you.

在电缆桥架内侧经常看到的英文字母多为MR和CT。其中，MR指的是金属线槽，CT指的是槽式桥架。电缆桥架厂家举例说明：如果您看到的是CT400×200/CE，那说明这是一个宽为400，高为200的电缆桥架，它可以沿着天棚或顶板面进行敷设；再比如MR200×100/CT，这表示这是一款宽为200，高为100的金属线槽，它可以沿着电缆桥架敷设。

The English letters often seen inside the cable tray are mostly MR and CT. Mr refers to metal trunking and CT refers to grooved bridge. Example of cable tray manufacturer: if you see ct400 × 200 / CE, which means that this is a cable tray with a width of 400 and a height of 200, which can be laid along the ceiling or top plate; Another example is mr200 × 100 / CT, which means that it is a metal trunking with a width of 200 and a height of 100, which can be laid along the cable tray.
