电缆桥架各自都都有什么样的优缺点?

电缆桥架是智能建筑的弱电系统,通常有多个信息监控和通信设施诸如BA(楼宇自动化)OA(办公自动化)CA(通信自动化)等相应的系统组成, 电缆桥架分为槽式托盘式和梯架式等结构,由支架托臂和安装附件等组成。选型时应注意桥架的所有零部件是否符合系列化通用化标准化的成套要求。建筑物内桥架可以独立架设, 也可以附设在各种建筑物和管廊支架上,应体现结构简单,造型美观配置灵活和维修方便等特点,全部零件均需进行镀锌处理,安装在建筑物外露天的桥架,如果是在邻近海边或属于腐蚀区,则材质具有防腐耐潮气。
Cable tray is the weak current system of intelligent building. It is usually composed of multiple information monitoring and communication facilities, such as BA (building automation), OA (office automation), Ca (Communication Automation) and other corresponding systems. Cable tray is divided into trough tray type and ladder type structures, which are composed of support arm and installation accessories. During type selection, pay attention to whether all parts of the bridge meet the complete set requirements of serialization, generalization and standardization. The bridge in the building can be erected independently or attached to various buildings and pipe gallery supports. It should reflect the characteristics of simple structure, beautiful appearance, flexible configuration and convenient maintenance. All parts need to be galvanized. The bridge installed outside the building in the open air. If it is near the sea or belongs to corrosion area, the material has anti-corrosion and moisture resistance.
电缆桥架有哪些样式?
What are the styles of cable tray?
梯级式电缆桥架

The utility model has the advantages of light weight, large load, beautiful appearance, simple structure and convenient installation. It is not only suitable for the installation of power cables, but also suitable for the laying of control cables.
槽式电缆桥架
Trough type cable tray
槽式电缆桥架是一种全封闭型电缆桥架。它适用于敷设计算机电缆通信电缆热电偶电缆及其他高灵敏系统的控制电缆等。它对控制电缆的屏蔽干扰和重腐蚀中环境电缆的防护都有较好的效果。
Grooved cable tray is a fully enclosed cable tray. It is suitable for laying computer cables, communication cables, thermocouple cables and control cables of other highly sensitive systems. It has a good effect on the shielding interference of control cables and the protection of cables in heavy corrosion environment.
梯级式托盘式槽式电缆桥架各自优缺点:梯级式汇线桥架具有良好的通风性能,不防尘不防干扰。槽式托盘式汇线桥架具有防尘防干扰性能。
Advantages and disadvantages of stepped tray and trough cable tray: the stepped manifold cable tray has good ventilation performance, no dust and no interference. Trough tray type junction bridge has dust-proof and anti-interference performance.
大跨距电缆桥架
Long span cable tray
当前大跨距电缆桥架一般是由拉挤玻璃钢型材组装而成,适用于电力电缆控制电缆照明电缆及配件等。与铁制桥架相比,具有使用寿命长(一般设计寿命为二十年)安装方便且成本低(比重仅为碳钢的1/4,施工中无需动火,单根桥架长度可达8米,甚至更长)切割方便不需维护等优越性。
At present, long-span cable trays are generally assembled from pultruded FRP profiles, which are suitable for power cables, control cables, lighting cables and accessories. Compared with the iron bridge, it has the advantages of long service life (the general design life is 20 years), convenient installation and low cost (the proportion is only 1 / 4 of that of carbon steel, there is no need for hot work in construction, and the length of a single bridge can reach 8m or even longer), convenient cutting and no maintenance.
组合式电缆桥架
Combined cable tray
组合式电缆桥架是一种新型桥架,是电缆桥架系列中的二代产品。它适用各项工程各种单位各种电缆的敷设,它具有结构简单配置灵活安装方便形式新颖等特点。
Combined cable tray is a new type of cable tray, which is the second generation of cable tray series. It is suitable for the laying of various cables in various units of various projects. It has the characteristics of simple structure, flexible configuration, convenient installation and novel form.
桥架,可以说应用的是越来越广的,种类也是越来越多的。那么作为桥架中,使用非常广的一个产品,也就是电缆桥架,在进行敷设的时候,有哪些需要注意的事项呢?可能有许多朋友对于什么是敷设并不是特别的清楚,其实所谓的敷设,就是指将线管的一处到另一处的安装。可以说是在电缆桥架安装中,非常常见的安装方式。下面就来说说电缆桥架敷设吊装时要注意些什么。
Bridge, it can be said that the application is more and more extensive, and the types are also more and more. Then, as a widely used product in cable tray, that is, cable tray, what should be paid attention to when laying? Many friends may not be particularly clear about what is laying. In fact, the so-called laying refers to the installation of wiring pipes from one place to another. It can be said that it is a very common installation method in the installation of cable tray. Let's talk about what we should pay attention to when laying and hoisting cable tray.
1.注意吊装:告诉你在进行电缆桥架吊装时,也是需要注意的,不仅仅在吊起装车时不能超载,而且在电缆轴心也是需要穿上一根强度足够的钢管的,这主要也是为了可以更好的保证吊装的全性的。
1. Pay attention to hoisting: tell you that you also need to pay attention when hoisting the cable bridge. Not only can you not overload when hoisting and loading, but also you need to wear a steel pipe with sufficient strength on the cable axis, which is mainly to better ensure the integrity of hoisting.
2.钢丝绳在进行钢管套牢的时候,还要看一下两边的间距不宜过小,好不要小于300mm。
2. When the steel pipe is fastened by the steel wire rope, the spacing between the two sides should not be too small, not less than 300mm.
3.电缆桥架在进行敷设时,认为还有一点也是需要注意的,那么就是在进行吊装的时候,吊装速度不宜过快,好缓慢进行。
3. When laying the cable tray, it is considered that there is another point that needs to be paid attention to, that is, when hoisting, the hoisting speed should not be too fast, so it can be carried out slowly.
4需要将敷设的地点进行提前的选定的,一般都会遵循这样的一个原则,那么就是以敷设方便为准,好选择在电缆起止点附近。总的来说,电缆桥架进行敷设需要注意的细节还有很多,除了以上的这些,认为那么在进行架设时也是需要注意一下电缆轴的转动方向是不是正确,一般来说,电缆引出端好不要在电缆轴的下方。
4. If the location of laying needs to be selected in advance, the principle will generally be followed, that is, the convenience of laying shall prevail, and it is better to choose near the starting and ending points of cables. Generally speaking, there are many details that need to be paid attention to when laying the cable tray. In addition to the above, it is considered that during erection, it is also necessary to pay attention to whether the rotation direction of the cable shaft is correct. Generally speaking, the cable outlet end should not be below the cable shaft.
