Problems solved by technology

If the aging of the cable is not easy to be found by people, the aging area of ​​the cable will become larger and larger, so that the current-carrying conductor will be exposed, and the risk of leakage accidents will become higher and higher.

Abstract

The invention discloses a pre-warning cable and a preparation method thereof. The cable has a warning function on local ageing leakage of the cable. The cable sequentially comprises a cable core, an isolation layer, an ion storage layer, an electrochromic layer and a wearing layer from the inside to the outside; when the cable core part of the cable is damaged to leak, ions in the ion storage layer are driven to the electrochromic layer; the ions and a photochromic material in the electrochromic layer are subjected to chemical reaction; and the photochromic material generates a compound with another color, so that people can observe the color change of the cable through the transparent wearing layer and obviously judge the damage to the cable.

Description

technical field [0001] The invention relates to the field of cable manufacturing, in particular to an early warning cable and a preparation method thereof. Background technique [0002] With the improvement of the economy and living standards, cables will be used in various industries such as home appliances and electronics. It can be said that cables can be seen everywhere, and our lives are inseparable from them. The traditional cable manufacturing method is to wrap a layer of insulating material around the energized conductor to play the function of insulation protection. [0003] Although the manufacturer will test the safety of the cables before leaving the factory to ensure that the cables are safe and qualified, but as the use time gets longer and longer, the insulating material will age, and the cables at this time are no longer safe. If the aging of the cable is not easy to be found by people, the aging area of ​​the cable will become larger and larger at this time...
