電纜橋架是什麽 電纜橋架該如何選擇?

在生活當中橋架常常出現在工業建造方麵,因此,來百姓接觸的會比較少。但是橋架後產生的物品就和生活息息相關了。那麽,接下來就和小編一起去了解下,電纜橋架是什麽?電纜橋架該如何選擇?
In our daily life, bridges often appear in industrial construction. Therefore, people will have less contact with them. But the goods produced after the bridge are closely related to life. So, next, let's go with Xiaobian to understand what the cable tray is? How to select cable tray?
電纜橋架是什麽?其實橋架就是一個能夠支撐和放電纜的支架。無論是建築工程,還是電力工程,隻要是需要鋪設電纜就必須要用到橋架。而電纜橋架作為整個布線工程的一個重要的配套項目,國內目前都還沒有的規範來指導,現在的市場非常稀缺這方麵的技術,因此各個生產廠家的規格形式都缺乏通用性。所以,無論是設計選型,還是電器的各個係統都要通過電纜數量、類型來合理的選定橋架。電纜橋架具有品種全、結構輕、造價低、施工簡單、安裝標準、外型美觀、應用廣、強度大、配線靈活等特點。
What is cable tray? In fact, the bridge is a support that can support and place cables. Whether it is construction engineering, or power engineering, as long as it is necessary to lay the cable, it must use the bridge. As an important supporting project of the whole wiring project, cable tray has no professional specification to guide at present in China. Now the market is very scarce in this aspect of technology, so the specifications of various manufacturers are lack of universality. Therefore, whether it is the design and selection, or each system of electrical appliances, we should reasonably select the bridge through the number and type of cables. Cable tray has the characteristics of complete variety, light structure, low cost, simple construction, standard installation, beautiful appearance, wide application, high strength, flexible wiring and so on.
1、電纜橋架材質選擇
1. Material selection of cable tray
電纜橋架工程設計常見的問題就是電纜橋架如何按照材料劃分,一般分為玻璃鋼、鋼製和鋁合金這幾種。而玻璃鋼的電纜橋架的質量較輕,耐腐蝕性和耐水性好,適合於化工廠使用。質地不易燃燒,使用壽命長,一般設計壽命在20年左右,但價格方麵比鋼製電纜橋架高3倍左右。施工的也非常方便,切割性強、容易組裝、安裝無需動火,對於化工廠這樣的工程非常實用。鋁合金電纜橋架也比較輕,荷載特性均與鋼質橋架基本相近。價格方便也比鍍鋅鋼製電纜橋架要高出20%,但是使用壽命是鋼製電纜橋架的5倍以上。
The common problem of cable bridge engineering design is how to divide the cable bridge into FRP, steel and aluminum alloy according to the material. The cable tray made of glass fiber reinforced plastic has light weight, good corrosion resistance and water resistance, and is suitable for use in chemical plants. The material is not easy to burn and has a long service life. The general design life is about 20 years, but the price is about 3 times higher than that of steel cable tray. Construction is also very convenient, cutting strong, easy assembly, installation, no fire, for chemical plants such as the project is very practical. Aluminum alloy cable tray is also relatively light, and its load characteristics are basically similar to those of steel cable tray. The price is convenient and 20% higher than galvanized steel cable tray, but the service life is more than 5 times of steel cable tray.
2、電纜橋架表麵防腐層類別選擇
2. Selection of anticorrosive coating on cable tray surface
電纜橋架表麵的防腐層主要分為:鍍鋅鎳、冷鍍鋅、熱浸鋅、粉末靜電噴塗等方式。鍍鋅鎳工藝壽命不小於30年,造價高,也適用於室外重腐蝕環境;冷鍍鋅工藝壽命不小於12年,造價一般,適用於室外輕腐蝕環境;而熱浸鋅工藝壽命不小於40年,造價高,適用於室外重腐蝕環境;粉末靜電噴塗工藝壽命不小於12年,價格一般,比較適用於室內常溫幹燥環境。所以,設計人員會根據工程環境條件等情況,來合理的選擇電纜橋架表麵的防腐層類別,並在會清晰地表達在設計文件中。
The anti-corrosion coating on the surface of cable tray is mainly divided into: galvanized nickel, cold galvanized, hot-dip galvanized, powder electrostatic spraying, etc. The service life of galvanizing nickel process is not less than 30 years, the cost is high, and it is also suitable for outdoor heavy corrosion environment; The service life of cold galvanizing process is not less than 12 years, the cost is general, and it is suitable for outdoor light corrosive environment; The life of hot dip galvanizing process is not less than 40 years, the cost is high, and it is suitable for outdoor heavy corrosion environment; The service life of powder electrostatic spraying process is not less than 12 years, the price is general, and it is suitable for indoor normal temperature and dry environment. Therefore, the designer will reasonably select the type of anti-corrosion coating on the surface of cable tray according to the engineering environmental conditions, and will clearly express it in the design documents.
以上,及時關於電纜橋架是什麽?及電纜橋架的選擇方式的相關內容,小編就介紹到這了。對於電纜橋架的選擇,主要還得看需要使用在哪些方麵來進行選擇,希望能幫助到您。
Above, what is the cable tray? And the selection of cable tray related content, Xiaobian introduced to this. For the selection of cable tray, it mainly depends on which aspects to use. I hope it can help you.
