In fact, cable trays are already ubiquitous in our daily lives, so what are the effects of cable trays? If you are currently inside a building, you may be able to see it as soon as you look up, but you have not noticed its existence as usual. The primary effect of cable trays is to facilitate the support of wires and cables inside the building, and to achieve various effects such as fire prevention, isolation of rodents, and external damage. Various cables are also regulated to ensure that they do not affect the beauty of the building.

二、电缆桥架的适用范围电缆桥架遍及应用于建筑工程当中，我们所居住的住宅、、写字楼等民用建筑和电厂煤矿等建筑物都是适用的;适用于电压40.s千伏以下的电力电缆以及控制电缆、照明配线等室内、室外架空、电缆沟、电缆隧道的敷设。

2、 The scope of application of cable trays is widely used in construction projects, including residential buildings, shopping malls, office buildings, and buildings such as power plants and coal mines where we live; Suitable for laying power cables with voltage below 40.s kV, as well as indoor and outdoor overhead, cable trenches, and cable tunnels for control cables, lighting wiring, etc.

三、桥架的优势电缆桥架在建筑物的是大规模运用的，而且越来越遭到人们关注，那么它究竟有哪些优势和特色呢？首要，电缆桥架具有应用广、品种全、强度大、结构轻、造价低、施工简略、配线灵敏、装置标准、外形漂亮的特色，对于公司进行技能改善、扩充电缆、维护检修带来简便。 其次，电缆桥架还可以在建筑物内部进行独立架设，也可以敷设在各种建筑物和走廊支架上，它的结构简略、造型漂亮、配置灵敏和修理方便等特色都造成了如今越来越受人关注的形象。 后，根据不同的地理环境或者装置环境，电缆桥架的挑选也是具有针对性的，例如在装置建筑物外面露天的桥架，就运用具有防腐、耐潮气功能的桥架，利于保护电缆，避免遭到腐蚀，也能增加桥架的运用期限，减少桥架的修理次数。

3、 The advantages of cable trays: Cable trays are widely used in buildings and are receiving increasing attention. So, what are their advantages and characteristics? Firstly, cable trays have the characteristics of wide application, complete variety, high strength, light structure, low cost, simple construction, sensitive wiring, standard installation, and beautiful appearance, which makes it easy for the company to improve skills, expand cables, and maintain and repair. Secondly, cable trays can also be independently erected inside buildings or laid on various building and corridor supports. Its simple structure, beautiful appearance, sensitive configuration, and convenient repair have all created an increasingly popular image nowadays. Afterwards, based on different geographical or installation environments, the selection of cable trays is also targeted. For example, for outdoor cable trays outside the installation building, anti-corrosion and moisture resistant cable trays should be used to protect the cables and avoid corrosion. This can also increase the service life of the cable tray and reduce the repair frequency of the cable tray.

四、桥架的结构特色桥架的结构特色可随工艺管道架空敷设，楼板，梁下吊装：室内外墙面以及柱壁隧道-电缆沟壁上的侧装。还可以在露天立柱或支墩上进行装置。大型多层桥架吊装或者立装时，应尽量选用工字钢立柱两侧对称敷设。电缆桥架可以进行水平、笔直敷设；可转角、T字形、十字形分支：还可调宽、调高、变径。

4、 The structural characteristics of the bridge can be laid overhead with the process pipeline, lifted under the floor slab and beam: side mounted on indoor and outdoor walls, as well as column wall tunnels - cable trench walls. It can also be installed on outdoor columns or piers. When lifting or erecting large multi-layer cable trays, it is recommended to use I-steel columns symmetrically laid on both sides as much as possible. Cable trays can be laid horizontally and vertically; Adjustable corner, T-shaped, and cross shaped branches: also adjustable in width, height, and diameter.
