The choice of materials is a matter of the physical and mechanical properties produced by each, compared against the intended function, as well as the environment, in which the trays are to be installed.
II. Surface Finish:
1. Zinc-plating cable trays are suitable for indoor use. The place where cold zinc-plating cable trays would work should be dry, ventilated, and corrosion free.
2. Hot-dip Galvanizing (HDG) cable trays are suitable for outdoor use. They should be used in a place where there is no acid, alkali and salty substance in case of short working life.
3. Powder-coated cable trays should be carried out in alkali and salt corrosion free site.
The cable trays have the advantages of high strength, reasonable structure, better load, flexible layout, easy construction, convenient installation and easy wire line extension. The electric cable bridge may be impractically laid along with the process tube, may under the floor, hoisted under the girder, or be placed in the room, outside of the wall, the column, the tunnel, or on the electric cable ditch wall, and also may be installed in the open-air column or frusta.
For horizontal layout cable bridge, it should be fixed in every 2m. For vertical layout cable trays, it should be fixed up in every 1.5 meters.
