About the cable tray installation should pay attention to what problem? Small make up for you to explain:

　　1.外观检查

　　1. A visual inspection

　　电缆桥架进人施工现场，应提交下列资料产品出厂合格证、省市级质监站定期检验报告及有关技术鉴定文件等电缆桥架板材厚度应满足有关要求。热镀锌的电缆桥架镀层表面应均匀，无过烧、挂灰、局部未镀锌等缺陷。静电喷塑应平整、光滑、均匀、不起皮，无气泡、水泡桥架本身应平整，无扭曲变形，内壁应光滑、无毛刺桥架焊缝表面应均匀，不得有漏焊、裂纹、烧穿等缺陷。

　　Cable tray into the construction site, should submit the following documents products certification, provincial monitoring stations regularly inspection reports and related documents of technical appraisal and so on cable tray plate thickness shall meet the relevant requirements. Hot dip galvanized cable tray coating surface should be uniform, without defects such as burn, hang ash, local not galvanized. Electrostatic pensu should level off, smooth, uniform, no peeling, no bubble, bubble bridge itself should level off, without distortion, inner surface should be smooth, no burr bridge weld surface should be uniform, can not have leakage defects such as welding, crack, burn through.

　　2.电缆桥架的安装位置

　　2. The installation position of cable tray

　　桥架水平敷设时，距地高度一般不宜低于2.5m。桥架多层敷设时，为了散热、维护以及防干扰的需要，桥架层间应留有一定的距离电缆桥架在与各种管道平行敷设时，其净距应符合有关的规定。

　　Bridge run level, is apart from the ground level usually should not be less than 2.5 m. Bridge multi-layer laying, in order to heat dissipation, maintenance, and the need of anti jamming, the bridge floor should keep a certain distance between cable bridge in parallel with all kinds of pipe laying, the net distance should comply with the relevant provisions.

　　3.支吊架的安装

　　3. The installation of the hanger

　　电缆桥架的支吊架质量应符合现行的有关技术标准电缆桥架水平敷设时，支撑跨距一般为1.5~3m一试垂直敷设时，固定间距不宜大于2m两相邻桥架托臂之间水平高度差不应大于10mm,两相邻桥架托臂垂直中线的垂直偏差不应大于20mm。

　　Cable tray of the steam-water quality shall comply with the relevant technical standards of the current level of cable tray installation, support span, as a general rule, be a try 1.5 ~ 3 m vertical run, fixed distance should not be greater than 2 m level height difference between two adjacent bridge bracket should be not more than 10 mm, two adjacent bridge bracket vertical center line of the vertical deviation should not be greater than 20 mm.
