There are many kinds of cable trays, mainly including trough type, tray type, ladder type and mesh structure. They are composed of brackets, support arms and mounting accessories. It can be erected independently or attached to various buildings and pipe gallery supports, and has the characteristics of simple structure, beautiful appearance, flexible configuration, convenient maintenance, etc. Next, let's introduce that Jinan cable tray has different choices in different environments.
1. In the engineering design, the layout of the bridge should be comprehensively compared according to economic rationality, technical feasibility, operation safety and other factors, and a good scheme that fully meets the requirements of construction, installation, maintenance and cable laying should be determined.
2. When the bridge is laid horizontally, its height from the ground is generally not less than 2.5m. When laying vertically, the part below 1.8m above the ground shall be protected by metal cover, except for laying in the special electrical room. The bridge shall be horizontally laid in the equipment interlayer, or less than 2.5m, and protective grounding measures shall be taken.
3. When used in corrosive environment, the bridge, trunking, supports and hangers shall be made of corrosion-resistant rigid materials. Or adopt anti-corrosion treatment, and the anti-corrosion treatment method shall meet the requirements of the project, environment and durability. For places with high requirements for corrosion resistance or cleanliness, aluminum alloy cable trays should be selected.
4. In areas with fire prevention requirements, Jinan cable tray and cable trough can be made of fire-resistant or flame-retardant plates, nets and other materials into closed or semi closed structures.
5. For cables that need to shield electromagnetic interference, or environmental requirements with external shadows, such as outdoor sunlight, oil, corrosive liquid, flammable dust, etc., cable trays without holes should be selected.
6. Cover plates shall be used for cable trays where dust is easy to accumulate; In public passages or outdoor intersections, it is recommended to add a base plate on the bottom bridge or use a perforated tray.
When using the pallet, the overall effect should be guaranteed to prevent the effect from affecting the use. In the later use of pallets, environmental factors will also account for a large proportion. The above is the specific introduction of selecting cable tray according to the installation environment.
