New Energy Power truck spare parts B-zone wiring harness TP-LH-01-00168

Built to guarantee stable power supply and signal transmission in the B-zone (a critical area for NEV energy management), this wiring harness delivers exceptional electrical performance. The conductors use oxygen-free copper (OFC) with 99.9% purity, minimizing resistance (≤0.018Ω/m for 1.0mm² wire) and ensuring efficient power delivery—reducing voltage drop by 20% compared to standard copper-clad aluminum wires. The twisted-pair design for signal wires (twist rate 10mm/pair) resists electromagnetic interference (EMI) from high-voltage components, maintaining signal integrity (bit error rate ≤10⁻⁹) for BMS data transmission. The crimped terminals (pull-out force ≥150N) form a secure connection, preventing intermittent contact that could cause B-zone component malfunctions or energy management failures

Engineered with multi-layer safety protections, the harness mitigates electrical risks in the B-zone’s high-voltage adjacent environment. The conductors are insulated with cross-linked polyethylene (XLPE) material, resistant to 125℃ continuous temperature and 150℃ short-term heat, preventing insulation melting from high-voltage heat radiation. A flame-retardant PVC outer sheath (UL94 V-0 rating) inhibits fire spread, while the integrated fuse holders (20A-50A) protect against over-current damage to B-zone controllers. The harness also features waterproof connectors (IP67 rating) with double O-ring seals, preventing water intrusion that could cause short circuits. All high-voltage adjacent wires are wrapped in aluminum foil shielding (coverage ≥95%), isolating EMI and ensuring compliance with CISPR 25 EMC standards

Designed to endure the harsh operating conditions of commercial NEVs, the harness exhibits exceptional durability across diverse climates and road conditions. The XLPE insulation maintains flexibility at -40℃ (northeast China winters) and resists aging at 85℃ (desert regions), passing 3000-hour thermal cycle testing (-30℃ to 100℃) without cracking. The outer sheath resists chemical corrosion from road salt, diesel fuel, and cleaning agents, with no volume change after 72-hour immersion in alkaline solution. The harness passes 500,000 vibration cycles (5-2000Hz, ISO 16750-3) and 1000-hour salt spray testing (ASTM B117) with no terminal corrosion. Its abrasion-resistant sheath (wear resistance ≥100,000 cycles) withstands friction from chassis components, ensuring a service life of ≥8 years/400,000km

Optimized for efficient NEV fleet maintenance, the harness features a pre-assembled and clearly labeled design. All branches, connectors, and terminals are pre-crimped and assembled at the factory, eliminating on-site wiring work and reducing installation time by 60%. Each connector housing is marked with component identifiers (e.g., “BMS-CON1”, “DC-DC-IN”) and color-coded (red for power, blue for signal), preventing misconnection. The harness includes pre-installed mounting clips that match the chassis’s original holes, requiring only a cable tie gun for fixation—no specialized tools needed. Clear length markers on each branch simplify routing, while the integrated service loops (100mm excess length) allow for easy disassembly during B-zone component maintenance. A single technician can complete the replacement in 30 minutes or less, minimizing truck downtime
