[0002] Cables are used in a wide range of applications, but cables are usually used in harsh working environments, sometimes in acidic or alkaline environments. Such working environments often require cables to have good corrosion resistance. However, at present, many cables have weak corrosion resistance. Corrosion of the cables will occur after being used for a period of time in an acidic or alkaline environment, which will seriously af...
