1. Support cable

通过自身的结构特性将电缆附着和支撑在建筑物(构筑物)上，或独立支撑电缆穿过隧道或洞穴、地下、空中等，主要是支撑电缆。它作为电缆的骨架，将电缆附在电缆桥架上，完成敷设。由于大部分电缆为柔性结构，无法独立完成敷设。利用电缆桥架的刚性结构，可以很好地支撑电缆电缆。

Attach and support cables on buildings (structures) through their own structural characteristics, or independently support cables through tunnels or caves, underground, air, etc., mainly to support cables. As the skeleton of the cable, it attaches the cable to the cable tray to complete the laying. Because most cables are flexible structures, they cannot be laid independently. The rigid structure of the cable tray can support the cable well.

2.保护线缆

2. Protective cable

电缆就像血液，主要功能是进行各种电力能量传输、信息传输、信息控制等。并吊起电缆以进行有效对齐。电缆进行保护。

Cable is like blood, and its main function is to carry out various electric energy transmission, information transmission, information control, etc. And hoist the cable for effective alignment. Cable protection.

例如，在铺设电力电缆时可以使用大跨度电缆桥架。可有效防止电缆自重造成的下垂，避免电缆直接暴露在大气中，隔绝阳光、雾、雨雪、风等因素对电缆的直接损坏。有效提高电缆的使用寿命。

For example, large-span cable trays can be used when laying power cables. It can effectively prevent the sag caused by the dead weight of the cable, avoid the direct exposure of the cable to the atmosphere, and isolate the direct damage to the cable caused by factors such as sunlight, fog, rain, snow, wind, etc. Effectively improve the service life of cables.

槽式电缆桥架用于敷设计算机电缆、通讯电缆、热电偶电缆等高敏感系统的控制电缆时，对控制电缆的屏蔽干扰和重腐蚀环境中电缆的保护有很好的作用。

The trough-type cable tray is used for laying control cables of highly sensitive systems such as computer cables, communication cables, thermocouple cables, etc., and plays a good role in shielding interference of control cables and protecting cables in heavily corrosive environments.

耐火电缆能保证电缆在遇到700°高温时仍能在30分钟1小时内有效工作，可用于高温车间或防火等级要求较高的建筑环境。消防工程电缆。

Fire-resistant cable can ensure that the cable can still work effectively within 30 minutes to 1 hour in case of 700 ° high temperature, and can be used in high-temperature workshop or building environment with high fire rating requirements. Fire engineering cable.

玻璃钢式具有较高的耐腐蚀性和防潮性，采用封闭式结构。在沿海地区和腐蚀较重的厂矿使用时，能很好地保护电缆不受潮气的直接腐蚀和损坏。

FRP type has high corrosion resistance and moisture resistance, and adopts closed structure. When used in coastal areas and factories and mines with heavy corrosion, the cable can be well protected from direct corrosion and damage by moisture.

不同材质和结构形式的电缆桥架功能不同，对电缆的保护也是多样化的。因地制宜选择合适的电缆桥架，可以满足不同条件和环境下电缆保护的需要。

The functions of cable trays with different materials and structural forms are different, and the protection of cables is also diversified. Selecting appropriate cable trays according to local conditions can meet the needs of cable protection under different conditions and environments.

3.管理线缆

3. Manage cables

利用电缆桥架管理电缆的功能，可以在建筑工程中科学布置能源(主要是电力)工程和智能工程的各种电缆，合理利用建筑空间，实现结构设计合理、施工简单方便，节省使用空间，布置美观，有利于达到维修更换的目的。

By using the function of cable tray management, various cables of energy (mainly power) engineering and intelligent engineering can be scientifically arranged in the construction project, and the building space can be reasonably used to achieve reasonable structural design, simple and convenient construction, save space, and beautiful layout, which is conducive to achieving the purpose of maintenance and replacement.
