1. When installing the cable, first punch the cable through the wall and then seal the hole with fireproof materials.

2、電纜的類型多種多樣將不同類型的電纜隔離開來(lái)，還有在敷設(shè)電纜的時(shí)候，把剛才不同種類的電纜分來(lái)敷設(shè)，由上到下敷設(shè)，先將高壓電纜的那一層，之后是電力電纜，后就是控制層的電纜。

2. There are various types of cables to isolate different types of cables. When laying cables, lay different types of cables from top to bottom, first the layer of high-voltage cables, then the power cables, and finally the cables of control layer.

3、在主的走廊到和別的走廊之間要增加防火門，在主走廊道每隔100就要增加一個(gè)防火段，然后電纜橋架要60米增加一個(gè)防火墻，防火墻、防火門它們的材料都是由防火隔墻板和一些無(wú)機(jī)材料組合而成的。

3. Fire doors shall be added between the main corridor and other corridors. A fire section shall be added every 100 meters in the main corridor, and then a firewall shall be added to the cable bridge for 60 meters. The materials of firewall and fire door are composed of fire partition board and some inorganic materials.

4、現(xiàn)在就是進(jìn)行防火隔離了，在通過(guò)電纜橋架上增加的防火材料然后制作出來(lái)的防火保護(hù)罩，而且要每三層之間要隔一層防火板才能夠防止火災(zāi)層蔓延的效果，一定要通過(guò)這種隔離增強(qiáng)的青島電纜橋架的耐候性，由這幾種防火組合起來(lái)，一定能有很好的防火效果。

4. Now it's time to carry out fire isolation. The fire protection cover made by adding fire-proof materials on the cable tray, and a layer of fire-proof board should be separated between every three layers to prevent the spread of the fire layer. The weather resistance of Qingdao cable tray must be enhanced through this isolation. Combined with these kinds of fire prevention, it must have a good fire-proof effect.
