AI Technical Summary
Existing charging pile cables have poor torsional resistance and are easily damaged after prolonged bending and twisting. They also have poor heat dissipation, which affects their service life, especially during fast charging when heat accumulates and causes aging.
Support bars and heat insulation cores enhance the tensile strength of the structure, thermally conductive fiber bundles accelerate heat dissipation, a flame-retardant layer blocks flame propagation, a pressure-resistant layer provides structural support, and an outer sheath with an anti-aging layer resists environmental factors and extends service life.
The charging cable has improved heat dissipation and flame retardancy, enhanced torsional resistance, and extended service life, making it suitable for vehicle environments where it may be run over.
