[0002] With the popularity of electric vehicles, as its core supporting facilities, the safety, reliability and convenience of use of charging pile become the focus of the industry. As a key component of electric energy transmission, the design of charging pile cable needs to meet the requirements of high strength, wear resistance, and tensile resistance.

[0003] However, the traditional charging pile cable faces the following problems in actual use: the current electric vehicle charging pile cable is mostly directly exposed to the outside for convenience of use, so the charging cable is designed to be relatively long during the design stage. When users use the cable to charge, they often experience pulling, stepping and crushing by cars, and over time, the charging cable will wear out, significantly reducing safety performance. Therefore, the use of cable protection device is particularly important. Although some cables use multi-layer sheath and metal armor structure, their protection ability is limited. Studies have shown that for every 1mm increase in sheath thickness, cable flexibility decreases by about 15%, making it difficult for users to pull, and the armor structure is prone to breakage after frequent bending.
