The installation of steel cable tray should be based on the electrical construction drawings and the trend of the cable tray should be measured, and it is suitable to use standard products and factory prefabricated parts.
The segment of the steel cable tray should be reasonable, and the connection position of the two segments should not be placed through the wall and across the floor hole.
The thickness of the connecting plate of the steel cable tray should be at least as thick as the pallet, or one grade of thickness can be selected.
The thickness of the steel cable tray cover can be one grade lower than or consistent with the pallet.
The steel cable bridge needs a cover plate in the indoor and outdoor environment which is easy to accumulate dust, flammable dust or sun protection, and ridges and drainage holes should be drilled in the outdoor environment where it often rains, so as to prevent the phenomenon of stagnant water after the steel cable bridge enters the water.
The specifications of various bends and accessories of the steel cable tray shall meet the engineering layout conditions and match the straight through of the bridge tray.
The specification and quantity of steel cable tray supports and hangers should be selected according to the technical configuration of bridge specifications, layers and spans, and meet the requirements of safety load.
According to the 2013 cable tray standard, the width of the tray and ladder is greater than 800mm. If it is made of steel, the thickness of the bridge should be 2.2mm. If it is aluminum alloy, the thickness of the bridge should be at least 2.5mm. If it is made of fiberglass, the minimum thickness of the bridge should be 5.0mm.
In the cable tray standard, when the width of the molded enhanced ladder tray is greater than 150mm and less than or equal to 400mm, the thickness of the side plate should be at least 1.2mm, the thickness of the rung should not be less than 1.2mm, and the thickness of the cover plate should not be less than 0.6mm.
According to the 2013 cable tray standard, the thickness of the connecting plate should be consistent with that of the tray and ladder rack, or one grade of thickness can be selected, and the thickness of the cover plate can be one level lower than that of the bridge tray plate.
When the width of the corrugated bottom tray tray in the cable tray standard is less than 300mm, the thickness of the side plate should be at least 1.0mm, the thickness of the corrugated bottom plate should be 0.7mm, and the thickness of the cover plate should not be less than 0.6mm.
