In China's infrastructure industry, cable bridge is a common one, and its function is mainly divided into three aspects: supporting cable protection, cable management and cable. Different functional features make it have different advantages. It is precisely because of these advantages that it can be widely known in the market.

作用一、支撐線纜

Function I. supporting cable

電纜槽基于其自身結構基礎的特性，將電纜連接到可支撐和固定的建筑物上，或者連接到獨立的支撐電纜上，有時在洞穴中、空中或地面上。支撐電纜是它的主要功能。橋架能對線纜起到骨架的作用，因此能夠在橋架整個工程里面完成敷設，絕大多數的索具有柔性結構特點，所以沒有辦法完成鋪設，這時利用橋架的剛性與它相結合，可以很好的組合線纜。

Based on the characteristics of its own structural foundation, the cable tray connects the cable to a supportable and fixed building, or to an independent supporting cable, sometimes in a cave, in the air or on the ground. Supporting cables is its main function. The bridge can play the role of skeleton for the cable, so it can be laid in the whole bridge project. Most of the rigging has the characteristics of flexible structure, so there is no way to complete the laying. At this time, the cable can be well combined by combining the rigidity of the bridge with it.

作用二、保護線纜

Role II: protect cables

電纜就像血液，它的主要功能是傳輸各種電力。事實上，它還包括信息控制和信息傳輸功能。電纜橋就像血管的外墻一樣，使電纜可以與外界隔離，電纜可以包裹、提升、再掛起，使電纜在電纜橋的保護下，能夠更好地發揮自己的作用。我們在此要提到的是，纜橋本身分為許多不同類型，例如：

Cable is like blood. Its main function is to transmit all kinds of power. In fact, it also includes information control and information transmission functions. The cable bridge is like the external wall of blood vessels, so that the cable can be isolated from the outside world. The cable can be wrapped, lifted and hung again, so that the cable can better play its role under the protection of the cable bridge. What we want to mention here is that the cable bridge itself is divided into many different types, such as:

大跨距電纜橋架可以在鋪設電力的同時使用，能夠更好地防止因自重引起的變松。

Long span cable tray can be used while laying power, which can better prevent loosening caused by self weight.

電纜槽可用于通信、計算機和高靈敏度系統。它可以在各種腐蝕性環境或干擾非常大的環境中起到保護作用。

Cable tray can be used for communication, computer and high sensitivity system. It can play a protective role in various corrosive environments or environments with great interference.

所以我們說不同的材料選擇和結構形式，可以使電纜橋具有不同的功能，所以電纜可以發揮多種保護作用。根據地區選擇合適的電纜機架，以滿足不同條件和環境下的電纜保護需求。

Therefore, we say that different material choices and structural forms can make the cable bridge have different functions, so the cable can play a variety of protective roles. Select the appropriate cable rack according to the region to meet the cable protection requirements under different conditions and environments.

作用三、管理線纜

Role 3: manage cables

利用電纜橋架能管理電纜的特點，可以科學地利用和敷設建筑工程中使用的各種能源和電纜。這樣，在空間和結構設計上都可以達到合理的狀態。這種操作不僅使結構更加簡單方便，而且大大節省了使用空間。除了美觀的布局外，還能更好得方便后期的各種維護、維修和更換。

Using the characteristics of cable bridge to manage cables, we can scientifically use and lay all kinds of energy and cables used in construction projects. In this way, the space and structure design can reach a reasonable state. This operation not only makes the structure more simple and convenient, but also greatly saves the use space. In addition to the beautiful layout, it can also better facilitate various maintenance, repair and replacement in the later stage.

事實上，電纜線橋自身具備一定的特性，使其與傳統式電纜線不一樣。集中管理、多層次管理方式不同的建筑設施在功能上可能需求不同。然后，我們還可以以合理的方式規劃和設計電纜的分布，使它們較少受到空間和建筑設備的影響。

In fact, the cable bridge itself has certain characteristics, which makes it different from the traditional cable. Building facilities with different centralized and multi-level management methods may have different functional requirements. Then, we can also plan and design the distribution of cables in a reasonable way, so that they are less affected by space and building equipment.

我相信科技的發展可以更好地幫助我們讓各種建筑設備的更新換代更加的快速，其中青島電纜橋架在未來幾年一定會帶給我們更多的驚喜。除了它的多樣性外，它可以被越來越廣泛地使用，我們相信我們可以得到更有序的工作。

I believe that the development of science and technology can better help us make the upgrading of various construction equipment faster. Among them, Qingdao cable bridge will bring us more surprises in the next few years. In addition to its diversity, it can be used more and more widely, and we believe we can get more orderly work.
