1. Under the eaves. Cables can be used only when they are not exposed to sunlight or ultra-low temperature. It is recommended to use pipes.
2. On the outer wall. Prevent the wall from being damaged by indirect sunlight.
3. In a pipe (plastic or metal). For example, in pipes, pay attention to the damage of plastic pipes and the heat conduction of metal pipes.
4. Overhead use / overhead cable. Consider the sagging and pressure of the cable, which binding method is planned, and whether the cable can be indirectly irradiated by the sun.
5. It is indirectly laid in the underground cable trench, and the control range of this environment is extremely small. The device of cable trench shall stop the reflection of dry or wet level.
6. Underground pipeline. It is convenient for future promotion, cable replacement and isolation from external pressure and surrounding environment, and auxiliary pipeline is a better method. But don't expect that the pipeline will always be boring, which will affect the selection of cable varieties.
