實際上因環境不同，所選用的橋架也就不同，尤其是大跨距電纜橋架，基本建筑行業都需要用到它，今天，我們就來了解下大跨距電纜橋架的正常使用環境標準，下面濟南電纜橋架廠家為您解答。

In fact, due to different environments, the selected cable tray is different, especially the long-span cable tray, which is required by the basic construction industry. Today, we will learn about the standard of the normal use environment of long-span cable tray. Now, the cable tray manufacturer in Jinan will give you an answer.

一、大跨距電纜橋架正常使用環境標準：

1、 Environmental standards for normal use of long-span cable tray:

1、大跨距橋架在正常環境下，使用溫度要達到-20℃到55℃；

1. Under normal environment, the service temperature of long-span cable tray shall reach - 20 ℃ to 55 ℃;

2、相對濕度＜95%；

2. Relative humidity ＜ 95%;

3、安裝地點海拔高度不超過2000米；

3. The altitude of the installation site shall not exceed 2000m;

4、不同氣候的環境，選用不同氣候環境等級的橋架參數，按溫度、濕度、防火等；

4. For different climate environments, bridge parameters of different climate environmental levels shall be selected according to temperature, humidity, fire protection, etc;

5、橋架要有一定的防火功效；

5. The bridge shall have a certain fire protection effect;

二、特殊使用環境標準：

2、 Standards for special use environment:

1、敷設在不同化學腐蝕的環境：電纜橋架要做到耐鹽，耐酸、耐硫化氫、耐氯化氫等；

1. Laying in different chemical corrosion environments: the cable tray shall be salt resistant, acid resistant, hydrogen sulfide resistant, hydrogen chloride resistant, etc;

2、特殊環境下，大跨距電纜橋架表面要進行防護，防護的方式通常有三種：熱鍍鋅、電鍍鋅或鋅合金、熱固型粉末靜電噴涂或噴漆鍍鋅；

2. Under special circumstances, the surface of long-span cable tray shall be protected in three ways: hot galvanizing, electro galvanizing or zinc alloy, thermosetting powder electrostatic spraying or spray galvanizing;

3、無孔托盤(槽式)戶內不低于IP30，戶外不低于IP33；

4、耐火型橋架戶內不低于IP40，戶外不低于IP44；

4. Fire resistant cable tray shall not be less than IP40 indoors and IP44 outdoors;

5、環境越惡劣，大跨距電纜橋架的防護層厚度就要越厚；

5. The worse the environment is, the thicker the protective layer of long-span cable tray will be;

6、需要屏蔽電氣干擾的電纜網路，或有防護外部要求時，應選用帶蓋的槽式復合型防腐屏蔽電纜橋架；

6. For the cable network that needs to shield electrical interference, or when there are external requirements for protection, the covered trough type composite anti-corrosion shield cable tray shall be selected;

7、對于強腐蝕性環境，應選用F類復合環氧樹脂防腐屏蔽電纜橋架，包括配件；

7. For highly corrosive environment, type F composite epoxy resin anti-corrosion shield cable tray shall be selected, including accessories;

8、戶外環境要選用復合環氧樹脂橋架；

8. Composite epoxy resin bridge shall be selected for outdoor environment;

9、在容易積灰和其它需要遮蓋電纜橋架的地方，需要加蓋板；

9. Cover plates shall be added at places where dust is easy to accumulate and where cable trays need to be covered;
