Hot dip galvanized cable tray is a process of using electrolytic equipment to wash the cable tray through a degreasing plug, then placing it in a solution containing zinc salts, and connecting it to the negative stage of the electrolytic equipment. Place a zinc plate opposite the cable tray, connect it neatly to the electrolysis equipment, and then connect the power supply. When using the power supply to move from positive to negative, a layer of zinc cold plating will be deposited on the cable tray. The cable tray is processed first and then galvanized, with the primary purpose being to prevent corrosion. He is the same as the heavy-duty anti-corrosion coating in the production and coating engineering of cold galvanized cable trays, which also involves environmental maintenance, construction personnel, and public work hygiene. Environmental maintenance is also a primary development direction of cold galvanized cable trays. The cable tray in the freezer room has excellent environmental protection functions, which are reflected in the following aspects. Does not contain PH.cr. Hg and other heavy metals.

Because the solid content of cold galvanizing is as high as 77%, a single airless spraying can achieve a relatively high film thickness, reduce the amount of organic solvents used, and reduce dry energy consumption. These are measures that are beneficial for environmental maintenance. Moreover, galvanized cable trays are a type of building facility information that cannot be lacking in large-scale power engineering, because their special processing technology and composition information have more advantages and characteristics compared to other cables, which also makes the scope of use of galvanized cable trays more extensive.

When two sets of cable trays are laid parallel at the same height, the clear distance between them shall not be less than 0.6m. When the trough type large-span enters the building from outside, the slope of the bridge to the outside shall not be less than 1/100. When laying the inner cable straight, it should be fixed on the support of the bridge at the upper end of the cable and every 1.5 meters away. When laying horizontally, it should be fixed at the beginning, end, turn, and every 3-5 meters away.

Generally speaking, for a large number of cables, straight bending plates and straight lead up racks can be used, while for a few cables, guide plates or pipes can be used, indicating the lead down method. The cable tray should be raised 2.2 meters above the ground, and the distance from the top of the tray to the ceiling or other obstacles should not be less than 0.3 meters. The width of the tray should not be less than 0.1 meters, and the filling rate of the cross-section inside the tray should not exceed 50.
桥架与用电设备交越时,其间的净距不小于0.5m。 在平行图上绘出桥架的路由,要注明桥架起点、完毕、拐弯点、分支点及升降点的坐标或定位尺度、标高,如能制作桥架敷设轴侧图,则对材料核算将更准。 直线段：注明全长、桥架层数、标高、类型及标准。
When crossing the bridge and electrical equipment, the clear distance between them shall not be less than 0.5m. Draw the route of the cable tray on a parallel diagram, indicating the coordinates or positioning scale and elevation of the starting point, end, turning point, branch point, and lifting point of the cable tray. If a cable tray laying axis side diagram can be made, the material accounting will be more accurate. Straight section: indicate the total length, number of bridge layers, elevation, type, and standard.
