托盘式电缆桥架负有构造简单、器件丰富、部署灵活、动土安装简单、维修方便等特征。桥架还有何不可起到很好的护卫和防腐用意，避免地缆在外环境中，幸免或压缩受罪、雾天、雨雪、老化等因素对光缆的直接影响，并可延长电缆的使用时间。耐酸桥架还方可使电线在火警正常办事一段时间。出于绋相像刚度较低，在大跨度管架或支吊架上，就此桥梁方可起到撑持、存储和合理计划性的作用。石拱桥还实有良好的电磁遮风挡雨效验，方可对传导仪器信号的电线起到很好的抗干扰意向。

The tray type cable tray has the characteristics of simple structure, rich components, flexible deployment, simple excavation and installation, and convenient maintenance. Why not provide good protection and anti-corrosion for the cable tray, to avoid the direct impact of factors such as suffering, fog, rain and snow, aging, etc. on the cable in the external environment, and to extend the service life of the cable. Acid resistant cable trays can also allow wires to function normally during a fire for a period of time. Due to the low stiffness of the bridge, it can only be supported, stored, and planned reasonably on large-span pipe supports or hangers. The stone arch bridge actually has good electromagnetic wind and rain shielding effect, in order to have a good anti-interference intention on the wires that transmit instrument signals.

电缆桥架是指铺设电缆着有的的直段、弯头、三通、十字、变径等附件，以及支架、间架等，托盘式电缆桥架的连续刚性结构体系：

Cable tray refers to the continuous rigid structural system of tray type cable tray, which includes accessories such as straight sections, elbows, tees, crosses, and reducers for laying cables, as well as brackets and shelves

1、按常用资料可分为：铝合金、碳钢、不锈钢、玻璃钢、电木、复合材料。

1. According to commonly used information, it can be divided into aluminum alloy, carbon steel, stainless steel, fiberglass, bakelite, and composite materials.

2、按常见款型可分成：无孔托盘（别称槽型、槽盒）、穿孔托盘、拼装托盘、网格托盘、梯架。

2. According to common styles, it can be divided into: perforated tray (also known as slot type or box), perforated tray, assembled tray, grid tray, and ladder.

3、耐火料槽箱按构造可分成不同的构造：

3. The refractory material tank box can be divided into different structures according to its structure:

4、耐火料槽箱根据测验尺度下的耐火性能可分为三个等级（局部尺度分为3个品级，行使I、II、III或NH1、NH2 NH3标明，流光为三个阶段60 , 45, 30 分钟）：

4. The refractory material tank can be divided into three levels based on the fire resistance performance under the test scale (local scale is divided into three levels, marked with I, II, III or NH1, NH2, NH3, and three stages of flowing light for 60, 45, and 30 minutes):

5、大桥常用的跨度可分为：2000、3000、4000、6000mm。

5. The commonly used spans of bridges can be divided into 2000, 3000, 4000, and 6000mm.

6、常用的过桥幅面可分成：100、200、300、400、500、600、800、1000mm。

6. The commonly used bridge sizes can be divided into: 100, 200, 300, 400, 500, 600, 800, and 1000mm.

7、常用的桥架高度可分为：50、100、150、200、300mm。

7. The commonly used bridge heights can be divided into: 50, 100, 150, 200, and 300mm.

8、大桥基点及一个劲扣件的外表保护层一般总括：热镀锌、镀锌锌、热固性碎末静电喷溅、油漆、防火涂料、阳极氧化。

8. The outer protective layer of the bridge base point and a fastener generally includes hot-dip galvanizing, galvanized zinc, thermosetting electrostatic spraying of debris, paint, fireproof coating, and anodizing.

9、新式桥架：托盘式电缆桥架是指所有节约资源（钢）和效应的大桥气派。桥架役使高低不平笑纹结构技能，有增无减桥架强度，减掉骨材损耗，日增化痰面积，利用热传导和热交换技能，改进电缆周转的温度环境。桥架，减少线损，达成勤政减排的目的。

9. New type cable tray: Tray type cable tray refers to the bridge style that saves resources (steel) and effects. The skill of using uneven smile patterns on the bridge structure increases the strength of the bridge without decreasing it, reduces bone material loss, and increases the area of phlegm. By utilizing heat conduction and exchange skills, the temperature environment for cable turnover is improved. Bridge, reduce line loss, and achieve the goal of diligent governance and emission reduction.
