New Energy Power truck parts Power receiving socket positive 1 to battery junction box automatic positive 1 high-voltage cable assembly 2105510-X69C2

Built to serve as the core transmission link between the charging socket and battery system, this cable assembly delivers exceptional electrical performance. The conductor adopts 99.9% pure oxygen-free copper (OFC) with a 70mm² cross-section and a 7×26 strand structure, minimizing DC resistance to ≤0.00026Ω/m. This low resistance reduces voltage drop to ≤1.8V at 300A load—critical for DC fast-charging, as it ensures the battery receives stable voltage and current, shortening charging time by 15% compared to standard cables. The 300A continuous current capacity (600A peak for 15s) supports 180kW+ fast-charging systems, while the uniform conductor stranding enhances current-carrying stability, avoiding local overheating during high-power transmission

Engineered as a safety-critical component in NEV high-voltage networks, the cable assembly integrates multi-layer protection mechanisms. The conductor is insulated with cross-linked polyethylene (XLPE) material, providing 15kV/mm dielectric strength and resisting 160℃ continuous temperature—preventing insulation breakdown and electric arcing even in extreme charging conditions. A double-layer shielding structure (copper braid + aluminum foil, total coverage ≥98%) isolates electromagnetic interference (EMI) from charging equipment, protecting the vehicle’s BMS and VCU from signal disruption. The flame-retardant PVC outer sheath (UL94 V-0 rating) inhibits fire spread, while the connectors feature IP67 waterproofing and integrated high-voltage interlock (HVIL) pins that trigger system shutdown if disconnected, eliminating electric shock risks

Designed to endure the harsh operating environments of commercial NEVs—including frequent charging cycles and road hazards—the cable assembly exhibits exceptional durability. The XLPE insulation maintains flexibility at -40℃ (northeast China winters) and resists aging at 95℃ (engine bay and charging heat), passing 3000-hour thermal cycle testing (-30℃ to 110℃) without cracking or hardening. The outer sheath resists chemical corrosion from road salt, battery electrolyte, and cleaning agents, with no volume change after 72-hour immersion in alkaline solution. It passes 500,000 vibration cycles (5-2000Hz, ISO 16750-3) with no connector loosening and 1200-hour salt spray testing (ASTM B117) with no shielding corrosion, ensuring a service life of ≥8 years/400,000km

Optimized for efficient NEV fleet maintenance and assembly, the cable assembly features a pre-assembled plug-and-play design that reduces installation time by 60%. It comes fully terminated with connectors pre-tightened to OE torque specifications (20-25N·m), eliminating on-site crimping or wiring work. The integrated nylon mounting clips match the chassis’s original holes, requiring only a cable tie gun for secure routing. The connectors’ keyed design and color-coding (bright red for positive) prevent reverse installation, while a 150mm service loop at the midpoint allows for easy disassembly during battery junction box or socket maintenance. The cable’s printed length markers and part number labels facilitate quick identification, enabling a single technician to complete replacement in 30 minutes or less—minimizing truck downtime
