[0002] With the increasing depletion of global fossil energy and the deterioration of the global environment, the use of new energy to replace existing fossil energy has become one of the important research topics of countries around the world, and it is also an inevitable trend of social development. At present, my country has become the world's largest automobile consumer. In 2013, the automobile sales volume exceeded 21 million, and the number of automobiles in use exceeded 137 million. On the one hand, with the improvement of residents' income level, the demand for automobile consumption has grown rapidly; on the other hand, under the pressure of environmental pollution and energy shortage, many cities have begun to implement purchase restrictions. This has caused a contradiction in the supply of the automobile consumer market, which has brought opportunities for the development of the new energy automobile industry. The many social problems of fossil energy vehicles have prompted major automobile companies to compete to develop various new pollution-free and environmentally friendly vehicles. Electric vehicles use electricity as energy and convert electrical energy into mechanical energy through electric motors, which is completely in line with the concept of developing zero-pollution vehicles. Therefore, electric vehicles have been rapidly developed as an important way to solve problems such as resource shortages and environmental pollution. With the increasing number of new energy vehicles, new energy and green travel have gradually become a new lifestyle. Charging piles are increasingly appearing in life, so electric vehicle DC (AC) charging pile cables have become the "heart" of charging piles, and more and more charging gun cables are equipped with them. The cables used for charging guns are moved very frequently, and the flexibility requirements are getting higher and higher. Moreover, many car charging stations and gas stations are now built together, so it is inevitable that there are oil molecules in the venue that cause corrosion to the cable sheath.
