我們都知道橋架在電力系統(tǒng)中應(yīng)用的重要性，是我們生活正常運轉(zhuǎn)的保障，橋架由于應(yīng)用環(huán)境不同，橋架種類也不同， 那么高品質(zhì)的橋架有哪些共性存在呢？

We all know the importance of bridge application in the power system, and it is the guarantee for the normal operation of our life. Due to different application environments, bridge types are also different. What are the commonalities of high-quality bridges?

在全封閉橋架中進行敷設(shè)的時：

When laying in the fully enclosed bridge:

1、清潔清掃。一個好的工作環(huán)境是工作能否有序而有效進行的，所以我們在事先一定要做好線管的清理，并要將管內(nèi)的污物和積水都清理干凈。

1. Cleaning and cleaning. A good working environment is the key to whether the work can be carried out in an orderly and effective manner. Therefore, we must do a good job in cleaning the pipeline in advance and clean up the dirt and water in the pipeline.

2、有序不亂。在全封閉橋架內(nèi)部進行電纜或者電線的敷設(shè)工作時候，我們一定要先確保電纜或者電線是否排列整齊，如果可以將它們進行捆扎就更好了。在這個過程中要注意線纜不可以有絞擰、接頭、鎧裝壓扁、護層斷裂和表面有嚴重劃傷的情況。

2. Orderly and orderly. When laying cables or wires inside the fully enclosed bridge, we must first ensure whether the cables or wires are arranged neatly. It would be better if they can be bundled. During this process, it shall be noted that the cable shall not be twisted, spliced, flattened armor, broken sheath or severely scratched on the surface.

3、基本的絕緣性工作是要做好的，并且像是密封、防水等方面的工作也是不能夠忽視的。

3. The basic insulation work should be done well, and the work such as sealing and waterproof should not be ignored.

4、我們可以在各種電纜線上有明確的標識，這樣也可以更加便于我們之后的維護和保養(yǎng)。

4. We can have clear marks on various cable lines, which can also be more convenient for our future maintenance.

濟南電纜橋架的安裝對環(huán)境的要求：

Environmental requirements of bridge installation:

1）橋架既適用于動力電纜的安裝，也透用于控制電纜的敷設(shè)。橋架其表面處理分為鍍和噴漆兩種，在重腐蝕環(huán)境中可特殊防腐處理。橋架備有護罩，其所有配件與托盤式、槽式橋架通用。

1) The bridge is applicable to both the installation of power cables and the laying of control cables. The surface treatment of the bridge is divided into plating and painting, and special anti-corrosion treatment can be carried out in heavy corrosive environment. The bridge is equipped with a shield, and all its accessories are common to tray type and trough type bridges.

2）橋架、線槽及其支吊架使用在有腐蝕性環(huán)境中，應(yīng)采用耐腐蝕的剛性材料制造，或采取防腐蝕處理，防腐蝕處理方式應(yīng)滿足工程環(huán)境和耐久性的要求。

2) The cable tray, trunking and its supports and hangers used in corrosive environment shall be made of corrosion-resistant rigid materials or treated with anti-corrosion treatment. The anti-corrosion treatment method shall meet the requirements of engineering environment and durability.

3）橋架在有防火要求的區(qū)段內(nèi)，可在電纜梯架、托盤內(nèi)添加具有耐火或難燃性能的板、網(wǎng)等材料構(gòu)成封閉或半封閉式結(jié)構(gòu)，并采取在橋架及其支吊架表面涂刷防火涂層等措施，其整體耐火性能應(yīng)滿足有關(guān)規(guī)范或標準的要求。

3) In the section with fire protection requirements, the cable ladder and tray can be added with plates, nets and other materials with fire-resistant or flame retardant properties to form a closed or semi closed structure, and measures such as painting fire-resistant coating on the surface of the bridge and its supports and hangers shall be taken. The overall fire resistance performance shall meet the requirements of relevant national codes or standards.

4）在工程防火要求較高的場所，不宜采用鋁合金橋架。

4) Aluminum alloy bridge should not be used in places with high fire protection requirements.

橋架是石油、化工、輕工、電視、電訊等方面應(yīng)廣泛的一種。它具有重理輕、載荷大、造型美觀、結(jié)構(gòu)簡單、安裝方便等優(yōu)點。如果您有選購需求的話，就來我們網(wǎng)站http://m.ymmgjx.net咨詢了解吧。
