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;
3. Perforated tray (slot type) shall not be less than IP30 indoors and IP33 outdoors;
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;
The above is the standard for the use environment of long-span cable tray, and I hope it will be helpful to you when purchasing. Come to our website if you need http://www.yeeones.com Ask and understand!
