If the cable to be stored for a long time, according to the location of the cable, the following considerations should be taken: 1. Under the eaves. The standard local area network cable can be applied only if the cable is not directly exposed to sunlight or ultra-high temperature, and a pipeline is recommended. 2. On the outer wall. Avoid direct sunlight to the wall and man-made damage. 3. In the pipeline (plastic or metal). As in the pipeline, pay attention to the damage of plastic pipes and the conduction of metal pipes. 4. Suspended application/aerial cable. Consider the cable droop and pressure, which kind of binding method to use, whether the cable is directly irradiated by the sun. 5, directly in the underground cable trench laying, the environment is the smallest control. The installation of the cable trench shall be inspected regularly for dryness or moisture levels. 6. Underground pipelines. In order to facilitate future upgrades, cable replacement and the surface pressure and the surrounding environment isolation, auxiliary pipeline isolation, auxiliary pipeline is a better method. But do not expect the pipeline to remain dry forever, which will affect the choice of cable types.
