1. Definition
A DC charging pile cable is a specialized conductor designed for fastcharging systems of new energy vehicles. It connects the DC charging pile directly to the vehicle’s battery pack, delivering highvoltage direct current for rapid charging. Compared with AC cables, DC charging cables are required to withstand higher voltage and current levels while ensuring both electrical safety and mechanical durability.
2. Materials
Conductor: Stranded highpurity oxygenfree copper to achieve low resistance and high currentcarrying capacity.
Insulation: Crosslinked polyolefin (XLPO) or ethylenepropylene rubber (EPR), providing excellent heat resistance and dielectric strength.
Shielding: Braided copper wires or aluminumplastic composite layers to suppress electromagnetic interference.
Filler: Flameretardant fibers or flexible compounds to maintain roundness and enhance mechanical stability.
Sheath: Weatherresistant thermoplastic elastomer (TPE) or polyurethane (PU), offering protection against UV, oil, moisture, and abrasion.
3. Characteristics
High Current Capacity: Capable of supporting the large power output required for fast charging.
Safe and Reliable: Flameretardant, resistant to high voltage and arc discharge, ensuring secure charging.
Excellent Flexibility: Designed for repeated bending and manual handling without compromising durability.
Environmental Endurance: Stable performance under high temperature, low temperature, and humid conditions.
Integrated Functionality: Some DC charging cables incorporate control and signal lines to enable communication and safety monitoring.
4. Applications
• Connection between DC fast charging piles and electric vehicle battery packs.
• Main transmission cables for public fastcharging stations and urban DC charging facilities.
• Core cables for largescale highpower charging systems, such as fleet or depot charging solutions.
5. Recommended Stripping Machine — WG-8570X
Adaptability: Specially engineered for large crosssection and compositestructure cables, making it ideal for precise stripping of DC charging cables.
Advantages:
• Servodriven system ensures clean cuts without damaging copper strands.
• Capable of handling multilayer shielding and thick insulation.
• Supports common fastcharging cable sizes from 16mm² to 70mm².
• Programmable settings allow quick adjustment for different cable types.
