Before power cable is put into work, there are two key replacements, one is the transportation link, the other is the storage link, why these two links are critical, because if the storage and transportation methods are wrong, it will directly cause damage to the quality of the cable , So as to reduce the safety and service life of the two years of use, then, what should be paid attention to in the transportation and storage of cables?
1. Generally, the purchased cables are in large quantities, so we will choose to store overhead cables that are not used temporarily in the warehouse, but the environment for storing the cables must be paid attention to, and they must be kept away from some acid and alkaline liquids, because these are corrosive Once the substance comes into contact with the cable, it will damage the cable, so if these substances are present in the warehouse, they must be stored separately.
2. In some warehouses, there may be some gases that can corrode metals or damage insulating materials. This is also special attention when storing cables.
3. Cables, like film, are very afraid of direct sunlight. Exposing to the sun will accelerate the aging of the cables. Therefore, the cables must not be stored in an environment exposed to sunlight, and the cable trays are also best not to be laid flat. There are probably two reasons for this. One is that the cable should have a certain distance from the two side baffles of the reel, otherwise it is easy to cause nails to wear the cable. The second point may cause confusion in the arrangement of the cables and affect the quality of the cables. .
4. Do not store the cables in the warehouse and just leave them alone. It is best to go to the warehouse regularly to roll the inventory cables. Rolling is to turn ABC cable reel upside down. This is also to avoid receiving it for a long time. The influence of ground moisture. Especially in summer, when it is rainy and humid, it should be rolled regularly, at least once every 3 months. In other seasons, it depends on the warehouse environment. If the warehouse’s humidity is high, roll more frequently.
5. Cable storage also has a shelf life. The general storage time is recommended to be controlled at one and a half years, and the longest should not exceed two years.
6. During transportation, handle with care, rigorously hit high places, throw and throw, etc., which will easily cause the sheath to crack
