电缆桥架由于凹凸瓦楞散热面积增大，又设计了上下冷热空气交换的散热结构，使桥架内的电缆导电体所产生的热量得到充分的散发，从而降低了线路的电阻值和损耗，提高了电能利用率，达到效果。

The energy-saving cable tray has an increased heat dissipation area due to the concave convex corrugated design, and a heat dissipation structure for exchanging hot and cold air between the upper and lower parts is also designed, which allows the heat generated by the cable conductors inside the tray to be fully dissipated, thereby reducing the resistance and loss of the line, improving the utilization rate of electrical energy, and achieving energy-saving effects.

电缆桥架的安装：

Installation of energy-saving cable tray:

1）外观检查：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。

1) Appearance inspection: When entering the construction site for energy-saving cable trays, the following documents should be submitted: product factory certificate, regular inspection report from provincial and municipal quality supervision stations, and relevant technical appraisal documents. The thickness of cable tray plates should meet relevant requirements. The surface of the hot-dip galvanized cable tray coating should be uniform, without defects such as overburning, hanging dust, and partial lack of galvanizing. Electrostatic spraying should be flat, smooth, uniform, without peeling, without bubbles or water bubbles. The bridge itself should be flat, without distortion or deformation, and the inner wall should be smooth, without burrs. The welding surface of the bridge should be uniform, without defects such as missed welding, cracks, burn through, etc.

2）电缆桥架的安装位置：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。

2) The installation position of cable tray: When the tray is laid horizontally, the height above the ground should generally not be less than 2.5m. When laying multiple layers of cable trays, in order to dissipate heat, maintain and prevent interference, a certain distance should be left between the tray layers. When cable trays are laid parallel to various pipelines, their clear distance should comply with relevant regulations.

3）支吊架的安装：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。

3) Installation of supports and hangers: The quality of supports and hangers for cable trays should comply with current technical standards. When laying cable trays horizontally, the support span is generally 1.5-3m. When laying vertically, the fixed spacing should not exceed 2m. The horizontal height difference between two adjacent tray support arms should not exceed 10mm, and the vertical deviation of the vertical centerline of two adjacent tray support arms should not exceed 20mm.

在安装电缆桥架除了小编在以上说的这三项之外，还有很多细节也需要注意，以免影响使用效果。

In addition to the three items mentioned above, there are also many details that need to be paid attention to when installing high-efficiency and energy-saving cable trays to avoid affecting the effectiveness of use.
