The automotive wiring harness serves as the "nervous system," responsible for transmitting power and signals to critical components such as engines, sensors, and lights. Statistics show that 35% of vehicle malfunctions are caused by wiring harness aging, ranging from dashboard failures to circuit shorts and even fire hazards. Choosing standards-compliant wiring harnesses has become an essential skill for both vehicle owners and maintenance professionals.

Core Quality Assessment Criteria

Material Reliability Verification

Baori employs high-purity oxygen-free copper (OFC) conductors with a conductivity rate exceeding 98% (vs. 90% for standard copper). Insulation materials undergo UL 94 V-0 flame retardant certification, maintaining flexibility at 85°C and meeting IATF 16949 automotive-grade requirements.

Process Rigor

Baori’s ultrasonic welding technology reduces contact resistance to <0.0005Ω (80% lower than traditional crimping methods). Each harness undergoes 128 automated inspections, including:

l X-ray inspection of terminal fill rates (≥99.5% pass rate)

l Salt spray testing (48-hour corrosion resistance)

l Thermal cycling (-40°C to 150°C, 50 cycles)

Certification Compliance​

As one of China’s first IATF 16949-certified manufacturers, Baori products meet:

l ISO 16750-4: 2,000-hour vibration/shock resistance testing

l UL 1581: 1,000V withstand voltage/70°C×168h aging test

l RoHS 2.0: Hazardous substance content 30% below EU limits

Customization Capabilities​​

For new-energy vehicles, Baori offers dual-shielded wiring harnesses​​ (shielding effectiveness ≥70dB) with liquid-cooling support. A leading EV manufacturer reported 42% EMI reduction and 67% lower fault rates​​ after adopting Baori solutions.
