电缆桥架是电路施工中常用的材料，因此不同的场地、不同的场合使用不同类型的电缆桥架。因此，电缆桥架的种类很多，在安装过程中需要了解的电缆桥架知识也很多，对于这些产品的使用还是需要做不同的测试。

Cable trays are commonly used in circuit construction, so different types of cable trays are used in different sites and occasions. Therefore, there are many types of cable trays, and there are many knowledge of cable trays that need to be understood during installation. Different tests are still required for the use of these products.

每种类型的电缆桥架都是在固定的地方使用的，所以在使用的时候需要选择他的类型。这也是选择电缆桥架时比较重要的一个环节。所以你需要知道有哪些类型的电缆桥架。

Each type of cable tray is used in a fixed place, so its type should be selected when using. This is also an important link in the selection of cable tray. So you need to know what types of cable trays there are.

电缆桥架的种类很多，有阶梯式电缆桥架和复合式电缆桥架，还有槽型和托盘型等，各有各的特点。本文的特点也是为了区分这些不同类型的电缆桥架方式，可以根据各自不同的特点来区分。

There are many kinds of cable trays, including ladder cable tray and composite cable tray, as well as trough type and tray type, each with its own characteristics. The characteristics of this paper are also to distinguish these different types of cable tray, which can be distinguished according to their different characteristics.

例如，在选型时，应注意桥架的所有部件是否满足系列化、通用化和标准化的全套要求。建筑物中的桥架可以独立承担，也可以附在各种建筑物（构筑物）和管廊支架上。应体现结构简单、外形美观、配置灵活、维修方便等特点。所有零件都需要镀锌。,安装在建筑物外露天的桥梁，如果靠近海边或属于腐蚀区域，材料必须具有防腐、防潮、附着力好、抗冲击性高的物理性能。

For example, during model selection, attention should be paid to whether all components of the bridge meet the full set of requirements for serialization, generalization and standardization. The bridge in the building can be borne independently or attached to various buildings (structures) and pipe gallery supports. It shall embody the characteristics of simple structure, beautiful appearance, flexible configuration, convenient maintenance, etc. All parts shall be galvanized., For bridges installed in the open air outside buildings, if they are close to the sea or belong to corrosive areas, the materials must have physical properties of anti-corrosion, moisture-proof, good adhesion and high impact resistance.

江南app官方入口在哪里看到厂家认为为了减轻重量，也可以采用铝合金索和玻璃钢桥梁，其外形尺寸和荷载特性与钢桥基本相似。大约1：3，按照两种材料的市场价格折算，铝合金桥架的成本比同类镀锌钢桥架高2.0倍。铝合金桥架具有外形美观、重量轻、安装方便等优点。

Jinan Bridge manufacturers believe that in order to reduce the weight, aluminum alloy cables and FRP bridges can also be used. Their overall dimensions and load characteristics are basically similar to those of steel bridges. About 1:3. According to the market price of the two materials, the cost of aluminum alloy bridge is 2.0 times higher than that of similar galvanized steel bridge. Aluminum alloy bridge has the advantages of beautiful appearance, light weight and convenient installation.

铝合金电缆桥架与重防腐涂层相同。铝合金电缆桥架的生产和涂装还涉及到环境保护以及施工人员和公众的工作卫生。因此，环保也是铝合金电缆桥架的首要发展方向。铝合金电缆桥架具有优良的环保功能，主要体现在以下四个方面：

The aluminum alloy cable tray is the same as the heavy anti-corrosion coating. The production and coating of aluminum alloy cable tray also involves environmental protection and the work hygiene of construction personnel and the public. Therefore, environmental protection is also the primary development direction of aluminum alloy cable tray. Aluminum alloy cable tray has excellent environmental protection function, which is mainly reflected in the following four aspects:

1、铝合金电缆桥架不含Ph、cr、Hg等重金属；

1. Aluminum alloy cable tray does not contain heavy metals such as pH, Cr and Hg;

2、经试验证明，大部分铝合金桥架不含甲苯、酮类、卤代烃等有毒物质。

2. Tests have proved that most aluminum alloy bridges do not contain toxic substances such as toluene, ketones and halogenated hydrocarbons.

3、铝合金电缆桥架在减少三废、降低能耗、提高环保社会效益等方面的作用更加显着。

3. Aluminum alloy cable tray plays a more significant role in reducing three wastes, reducing energy consumption and improving environmental protection and social benefits.
