With the popularization of new energy vehicles and the development of charging technology, fast charging cables have become an important part of achieving fast charging.

[0004] However, the existing fast-charging cables for new energy vehicles also have certain shortcomings.

Due to the influence of external environmental factors, when the cable is subjected to unexpected impact, the cable's compression resistance and protection effect are relatively weak;

[0005] Secondly, the existing fast-charging cables for new energy vehicles have a large current flow, which makes the cables themselves more efficient in generating heat. However, the simple multi-layer structure makes it easy for the cables to dissipate heat in an untimely manner, resulting in poor cable operation. Utility Model Content
