One of the latest advancements in this topic is the use of PVC encapsulated galvanized steel wire for submarine cable armor. PVC coating can prevent the penetration of seawater and air and then inhibit the corrosion of galvanized steel. This method has been applied in submarine cable projects in recent years. Another advancement is the use of corrosion monitoring systems for submarine cables, which can detect the corrosion rate and potential of the armor wire and provide early warning for maintenance. These systems can help extend the service life of submarine cables and reduce the risk of failure.
