Because the installation environment is different, there are certain standards to pay attention to in the selection of cable tray. Understanding this standard can be a good way to carry out the laying of cable trays and carry out work standards. Let Shandong bridge manufacturers explain it for you.
In general, in the environment with corrosive liquid or still smoke and dust, the cable Internet affected by household appliances must be shielded, or external safety protection measures must be taken, and the cable tray should be shielded by trough type anti-corrosion.
In the strong corrosion environment, composite epoxy resin adhesive corrosion-resistant and flame-retardant cable bridge should be selected. In addition, it should be noted that Toby and support frame also need to use the same raw materials.
In public safety passages or outdoor roads beyond the road surface, metal tray cable bridges can be selected, and large span cable bridges can also be appropriately used. Cable bridges can be selected and installed according to the customer's application regulations.
If the span in the environment exceeds 3M, it is necessary to select the hybrid bridge. In the outdoor dusty environment, or in the case of covering, it is generally necessary to add a rear cover plate to the cable tray. That can provide a good safety protection cable and help the smooth development of power distribution.
In the case of cable tray selection, we should first consider the material of cable tray. There are many kinds of cable tray materials, among which steel, carbon fiber products and aluminum alloy profiles are commonly used. The corrosion resistance of FRP is characterized by light quality, good corrosion resistance and difficult to ignite.
In the whole process of operation, different project environments and technical standards also have unique provisions for the structural shape of cable trays. Therefore, when purchasing cable trays, the construction environment and technical characteristics of the project should be fully considered.
We should pay attention to the service life of the cable tray. Some cable trays have a longer service life of up to 20 years, but the corresponding price is also more expensive, and not all people need to choose more expensive goods.
