35 mm²High-Voltage Automotive Cable for New Energy Vehicles
Product Overview
The 35 mm²high-voltage cable is an engineered power transmission component designed for critical high-current circuits within Battery Electric Vehicles(BEVs),Plug-in Hybrid Electric Vehicles(PHEVs),and associated charging equipment.It delivers robust performance for applications requiring higher power than auxiliary systems but serving as a secondary main or primary branch line.
Key Technical Specifications
Conductor Cross-Section:35 mm²
Conductor Material:High-purity,fine-stranded copper,tinned for enhanced corrosion resistance and solderability.
Voltage Rating:600V/1000V AC/DC
Current Capacity:Rated for continuous currents typically up to 250-300A(subject to thermal derating based on ambient temperature and bundle sizing).
Operating Temperature Range:-40°C to+125°C(150°C short-term peak capability with specific materials).
Insulation:High-grade,cross-linked polyolefin(XLPO/XLPE)providing excellent dielectric strength,thermal stability,and resistance to cracking.
Shielding:Comprehensive EMI/RFI shielding via a combination of aluminum-metallized polyester tape and a high-coverage tinned copper braid(≥85%).
Outer Jacket:Abrasion-resistant,flame-retardant jacket compliant with Low Smoke Zero Halogen(LSZH)standards.Resistant to automotive fluids,fuels,and ozone.
Core Features&Advantages
High-Current Performance:Optimized 35 mm²cross-section efficiently transmits substantial power with minimal voltage drop and thermal generation,supporting system efficiency and fast-charging capabilities.
Durability in Dynamic Environments:Constructed to withstand continuous vibration,mechanical stress,and repeated thermal cycling without degradation of electrical or physical properties.
Enhanced Safety&Reliability:Multi-layer construction ensures exceptional insulation integrity,effective fault containment,and reliable operation under electrical overloads.The flame-retardant LSZH jacket enhances safety in case of thermal events.
Superior Electromagnetic Compatibility(EMC):The dual-layer shielding architecture effectively contains electromagnetic emissions and protects the cable from external interference,crucial for the stable operation of surrounding vehicle electronics.
Balanced Flexibility:Despite its larger gauge,the finely-stranded conductor design allows for manageable bending and routing during vehicle assembly,accommodating complex layouts within chassis and powertrain areas.
Primary Applications
Secondary Main Power Feeds:Connections from the main battery junction box to major subsystems.
Fast-Charging Circuitry:Critical wiring within the vehicle for DC fast-charging inlet connections and related distribution.
High-Power Auxiliary Systems:Primary power supply for high-demand components such as electric traction compressors and high-capacity PTC heaters.
Powertrain Connections:Alternative or supplementary wiring between inverters,DC-DC converters,and electric motors in certain vehicle architectures.
Charging Infrastructure:Internal cabling for DC fast-charging stations.
Compliance&Standards
Engineered to meet or exceed the requirements of major international automotive and electrical standards,including:
Automotive:ISO 6722,ISO 19642,LV214
Safety&Material:Flame resistance per UL 1581/UL 62(FT-2/VW-1),RoHS,and REACH compliance.
Summary
The 35 mm²High-Voltage Cable is a robust and reliable solution for demanding power transmission applications in modern electric mobility.It fills a critical niche between ultra-high-power main cables and lower-power auxiliary wires,offering an ideal balance of current-carrying capacity,physical manageability,and comprehensive safety features for next-generation EV and charging system designs.
