1、 Cable suspension in the air: first of all, we must consider the sag and pressure of the cable. After the test, we decide which binding method to use, and then solve the problem of whether the cable is directly exposed to sunlight.

First, the suspension cable in the air: first, we must consider the cable sag and pressure. After the test which is determined by the use of a binding mode, and then to solve the problem of whether the cable is directly exposed to sunlight and other issues.

二、布在外墙上的电缆：布线在外墙上的电缆，前期的都会考虑到解决风吹雨淋等问题，但是主要要解决的是避免阳光直接照射墙面及人为损坏。

2、 Cables laid on the outer wall: for the cables laid on the outer wall, the early stage will consider solving the problems such as wind and rain, but the main solution is to avoid direct sunlight on the wall and human damage.

Second, cloth on the wall of the cable: on the wall of the cable wiring, early will be taken into account to resolve the wind and rain, etc., but the main problem to be solved is to avoid direct sun exposure to the wall and man-made damage.

三、管道里(塑料或金属的管道)：不同的材质的管道道内的温度、湿度、导热等都不一样，所以要注意塑料管道的损坏及金属管道的导热。

3、 In pipes (plastic or metal pipes): the temperature, humidity and heat conduction in pipes of different materials are different, so pay attention to the damage of plastic pipes and the heat conduction of metal pipes.

Third, the pipe (pipe plastic or metal): temperature, humidity, thermal conductivity of different materials in the pipeline are not the same, so pay attention to thermal damage and metal pipe plastic pipe.

四、布在屋檐下：电缆只在不直接暴露在阳光照射或超高温下,标准局域网电缆就可以应用,建议使用管道。

4、 Cloth under eaves: Standard LAN cables can be used only when they are not directly exposed to sunlight or ultra-high temperature. It is recommended to use pipes.

Fourth, the cloth in the eaves: only in the cable to avoid direct exposure to sunlight or ultra high temperature, standard LAN cables can be applied, recommend the use of pipeline.

五、直接在地下电缆沟中铺设：这种环境是控制范围更小的，电缆沟的安装要定期进行干燥或潮湿程度的检查。

5、 Laying directly in the underground cable trench: this environment is the minimum control range, and the installation of cable trench should be checked regularly for the degree of dryness or humidity.

Fifth, the laying of underground cables directly in the ditch: This is the smallest control range, cable installation to regularly check the degree of dry or wet.

六、地下管道：为便于今后的升级,电缆更换以及与表面压力和周围环境隔离,辅设管道相隔离,辅设管道是一个较好的方法。但不要寄希望于管道会永远保持干燥,这将影响对电缆种类的选择。

6、 Underground pipeline: in order to facilitate future upgrading, cable replacement and isolation from surface pressure and surrounding environment, auxiliary pipeline is a better method. But don't expect the pipes to stay dry forever, which will affect the selection of cable types.

Sixth, the underground pipeline for future upgrades, cable replacement and surface pressure and the surrounding environment and isolation, auxiliary pipe isolation, auxiliary pipeline is a good method. But don't hope on the pipeline will always keep dry, it will impact on the cable selection.
