There is a lot of demand for cable tray in the current market. When we learn about cable tray manufacturers, we can also see the specific product types? In this way, we should look at the basic situation in the actual selection. After knowing the cable tray product model, we believe it will be more convenient to use.
Everyone knows that the fire protection requirements for cable tray construction are very high. However, few people know where specific fire protection requirements can be expressed. Let's take fireproof metal cable tray as an example to understand the fire protection requirements of cable tray.
Fireproof cable tray is sprayed with a layer of fireproof paint on the surface of ordinary cable tray to prevent fire and flame retardancy! In fact, the bridge itself will not catch fire, and only the cable and fire retardant paint can catch fire.
At present, the fireproof cable tray is mainly based on the national inspection standards for fireproof cables. The thickness of fire retardant paint is required to be greater than 1mm, and the fire resistance must be greater than 30 minutes. This is the standard for the effect of fire retardant paint on general fire resistant cables, which also has a relationship with the price. Some are cheap and some are expensive, and the effect of expensive is better. The fire retardant is basically steel, and the outer layer of fire retardant cables is also painted with a layer of fire retardant material. Also ensure that the adjacent slot boxes have good electrical connections.
Of course, in order to ensure high fire resistance, in addition to complying with the fire protection requirements of cable bridges and purchasing good fire retardant paint, the maintenance of cable bridges after installation should also be done well, not only after the completion of the initial construction, but also during the use process. Relevant departments should test the cable bridges at regular intervals, especially the fire resistance of cable bridges.
