Do you have the same feeling with me? Cable tray seems to be far away from our life. It's hard to see it in our daily life, but cable tray is very common in our life. Usually, because we can't live without cables, we can't live without cable trays. Next, let's take a look at the factors to pay attention to when choosing cable tray.

1.在工程设计中，应根据经济原理，技术可行性，操作安全性等因素对电缆桥架设计进行综合比较，确定更好的方案，并充分满足施工要求，安装，维护和布线。

1. In the engineering design, the cable tray design should be comprehensively compared according to the economic principle, technical feasibility, operation safety and other factors to determine a better scheme, and fully meet the construction requirements, installation, maintenance and wiring.

2.电缆桥架水平放置时离地面的高度通常不小于2.5m。垂直放置时，距离地面1.8 m以下的部分要用金属盖保护，除非放置在特定位置。电气室。如果电缆桥架水平放置在设备夹层或人行道上且小于2.5 m，则要采取接地保护措施。

2. When the cable tray is placed horizontally, the height from the ground is usually not less than 2.5m. When placed vertically, the part below 1.8 m from the ground shall be protected by metal cover, unless placed in a specific position. Power Supply Room. If the cable tray is horizontally placed on the equipment mezzanine or sidewalk and less than 2.5 m, grounding protection measures shall be taken.

3.在腐蚀性环境中使用时，电缆桥架，通道及其支撑和吊架要由坚固的耐腐蚀材料制成。或者，它们要经过防腐处理，并且防腐处理方法要满足工程环境和耐久性的要求。对于要求高度耐腐蚀或清洁的位置，应使用铝合金电缆桥架。

3. When used in corrosive environment, cable tray, channel and its support and hanger shall be made of solid corrosion-resistant material. Or, they should be treated with anti-corrosion treatment, and the anti-corrosion treatment method should meet the requirements of engineering environment and durability. For locations requiring high corrosion resistance or cleanliness, aluminum alloy cable tray shall be used.

4.在有防火要求的部分，电缆桥架可以添加耐火或不易燃的板，网和其他材料，以在电缆梯，货盘中形成封闭或半封闭的结构，并在车桥及其支架车架表面涂有防火涂料和其他尺寸的油漆。其总体耐火性要符合相关法规或标准的要求。在具有较高工程防火要求的地方，不应使用铝合金电缆桥架。

4. In the parts with fire protection requirements, fire-resistant or non flammable plates, nets and other materials can be added to the cable tray to form a closed or semi closed structure in the cable ladder and pallet, and the surface of the vehicle bridge and its support frame shall be coated with fire-resistant paint and other sizes of paint. The overall fire resistance should meet the requirements of relevant national regulations or standards. Aluminum alloy cable tray should not be used in places with high engineering fire protection requirements.

5.要防止电磁干扰或免受外部影响(例如外部阳光，油，腐蚀性液体，易燃粉尘和其他环境要求)的电缆线，要使用无孔电缆桥架。

5. Cable trays without holes shall be used for cables that are to be protected from electromagnetic interference or external influences (such as external sunlight, oil, corrosive liquid, flammable dust and other environmental requirements).

6.在容易积灰的地方，电缆桥架，公共通道或道路外部应使用盖板，在下部桥架上应加垫板，或使用无孔桥架。

6. In places where ash is easy to accumulate, cover plate shall be used for cable tray, public passage or outside of road. Base plate shall be added on the lower tray, or no hole tray shall be used.
