電纜橋架是由槽式、托盤式或梯級式的直線段、彎通、三通、四通組件以及托臂(臂式支架)、吊架等構成具有密接支撐電纜的剛性結構系統的全稱，它的安裝與保養有許多需要注意的地方，讓我們來看一下：

　　Cable tray is the full name for a rigid structural system consisting of straight sections, bends, tees, and tees, as well as support arms (arm brackets), hangers, and other components that tightly support cables in a trough, tray, or stepped manner. There are many aspects to pay attention to in its installation and maintenance. Let's take a look at:

　　1、在進行安裝時需要注意以下幾點：在有腐蝕或特別潮濕的場所采用橋架布線時，應根據腐蝕介質的不同采取相應的防護措施，并宜選用塑料護套電纜;橋架在穿過防火墻及防火樓板時，應采取防火隔離措施；幾組電纜橋架在同一高度平行安裝時，各相鄰電纜橋架間應考慮維護、檢修距離；如受條件限制需安裝在同一層橋架上時，應用隔板隔開；在電纜橋架布線時，其電纜不應有黃麻或其他易延燃材料外護層；電纜橋架不宜安裝在腐蝕性氣體管道和熱力管道的上方及腐蝕性液體管道的下方，否則應采取防腐、隔熱措施。

　　1. When installing, the following points should be noted: when using cable trays for wiring in corrosive or particularly humid places, corresponding protective measures should be taken according to the different corrosive media, and plastic sheathed cables should be selected; When cable trays pass through firewalls and fire-resistant floor slabs, fire-resistant isolation measures should be taken; When several sets of cable trays are installed in parallel at the same height, maintenance and repair distances should be considered between adjacent cable trays; If installation is required on the same level of bridge due to limitations, partitions should be used to separate them; When using cable trays for indoor wiring, the cables should not have an outer protective layer made of jute or other flammable materials; Cable trays should not be installed above corrosive gas pipelines and thermal pipelines, or below corrosive liquid pipelines. Otherwise, anti-corrosion and insulation measures should be taken.

　　2、電纜橋架的保養：電纜橋架的保養無外乎清潔和維護兩方面。清潔橋架時用純凈的軟布輕輕擦掉表面的灰塵即可，切記不要用濕布和酸性化學劑來擦拭，以防腐蝕橋架或誘導觸電等。清灰只是淺層保養的一種方式，想要更好地保養電纜橋架，可以使用光蠟。

　　2. Maintenance of cable trays: The maintenance of cable trays involves both cleaning and upkeep. When cleaning the bridge, gently wipe off the dust on the surface with a pure soft cloth. Remember not to use wet cloths or acidic chemicals to wipe, in order to prevent corrosion of the bridge or induction of electric shock. Clearing dust is just one way of shallow maintenance. To better maintain cable trays, you can use light wax.

　　由于電纜橋架的材質原因，使用時間一長，表面可能不如原先鮮亮，這時可以對其進行打蠟處理。將表面的灰塵清干凈，然后將光蠟涂抹在橋架表面，等晾干后再擦干。光蠟的使用不僅能使電纜橋架保持鮮亮的光澤，還能增強橋架的防止氧化能力。

　　Due to the material of the cable tray, after a long period of use, the surface may not be as bright as before. In this case, it can be waxed. Firstly, clean the dust on the surface, then apply a light wax to the surface of the bridge, and dry it after it has dried. The use of wax can not only maintain the bright luster of cable trays, but also enhance their ability to prevent oxidation.
