Wire and cable in the installation and storage need to pay attention to what problems

I. For different environments of installing and storing wire and cable, we summarize the following 6 points of attention: 1. Under the eaves: cables should only be used when the cable is in direct sunlight or at very high temperatures for ordinary LAN cables, and pipes are recommended. 2. is an external wall: direct sunlight should be prevented from shining on the wall and artificially damaging the cables. 3. Inside the pipe: pay attention to whether the plastic pipe is damaged, and the heat conduction of the metal pipe. 4. Suspended applications / Overhead cable: Consider cable sagging and gravity. Pay attention to the correct use of tying methods, whether the cable is masculinized, high temperature resistance (flame retardant).5. is laid directly in the underground cable trench, this environment is the least manipulative. Installation of cable trench should be regularly dryness or humidity checks. 6. underground pipelines: to facilitate the future replacement of cables, and isolation from surface pressure and the surrounding environment, supplemented by pipe isolation. However, care should be taken to keep the pipe dry. Second, due to improper installation or storage, wire and cable can cause what failures? What are the general causes?1. From the external damage in recent years, there are many cable failures caused by mechanical damage caused by external damage.2. Insulation moisture this situation is also very common, generally occurring in direct burial or rows of cable joints.3. Chemical corrosion of cables directly buried in the acid and alkali action area, often the cable armor, lead skin or outer sheath corrosion, so that the protective layer of the long-term exposure to chemical Chemical corrosion or electrolytic corrosion, so that the protective layer failure, insulation degradation, resulting in cable failure. 4. long time overload operation, due to the thermal effect of the current, the load current flowing through the cable will inevitably cause the conductor heat, while the insulation medium loss will also produce additional heat, so that the cable temperature rises and failure occurs.
