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.

在電纜橋架內側經常看到的英文字母多為MR和CT。其中，MR指的是金屬線槽，CT指的是槽式橋架。電纜橋架廠家舉例說明：如果您看到的是CT400×200/CE，那說明這是一個寬為400，高為200的電纜橋架，它可以沿著天棚或頂板面進行敷設；再比如MR200×100/CT，這表示這是一款寬為200，高為100的金屬線槽，它可以沿著電纜橋架敷設。

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.
