Dongguan UEALINK Electronics Expands Automotive Wire Harness Supply

The IATF16949 certified manufacturer offers customized high-voltage cable assemblies for EV, charging infrastructure and battery pack applications, with full global compliance documentation for export markets.

DONGGUAN, China – October 9, 2026 – Dongguan UEALINK Electronics Co., Ltd., a leading China-based automotive wire harness wholesaler and custom connection solution provider, today announced the expansion of its global supply capacity for automotive high-voltage wire harness and charging cable assemblies. This expanded product line is designed to address core pain points for global automotive clients, including insulation failure under extreme temperature and vibration conditions, delayed delivery from multi-supplier sourcing, lightweight design requirements, and high export compliance barriers. The new line features IATF16949 certified performance, 1000+ supporting global product certifications, and 25% weight reduction for standard harness assemblies. The expansion will serve clients across North America, South America and Eastern Europe, with global bookings open immediately and mass production shipping starting in October 2026.

Core Product Highlights and Technical Advantages

1. Automotive-grade high-voltage performance: All assemblies are manufactured under the IATF16949 automotive quality system, with a 1000V DC voltage rating, resistance to -40°C to 150°C temperature fluctuations, oil, hydrolysis and flame retardant properties. This reduces high-voltage system failure rates by 68% for EV applications, with zero recorded failures in high-temperature and collision durability tests for partner BYD.
2. One-stop integrated supply: The company provides end-to-end assembly of high-voltage cables, charging gun connectors and terminal components, eliminating delivery delays from multi-supplier sourcing. Bulk order on-time delivery rate reaches 100%, with zero production line downtime reported by existing automotive clients.
3. Flexible customization support: The company accommodates both small-batch sample orders for new product development and large-scale mass production, with custom specifications for insulation materials, bending radius and packaging to match specific client application requirements.

Global Compliance and Certification

To meet global market access requirements, the new automotive wire harness line is supported by the company’s full set of management system certifications, including ISO9001, ISO14001, IATF16949, AS9100 and SA8000. The company holds one of the most comprehensive UL certification portfolios for cables in Asia, with over 1000 product certifications including CSA, VDE, TUV, PSE and CCC. All products comply with IECQ QC 080000 hazardous substance management standards, meeting EU RoHS and REACH requirements to avoid customs detention, client rejection and regulatory penalties for export markets.

Supply and Customization Services

The expanded automotive wire harness line is available for global bookings immediately via the company’s official website, with mass production shipping starting in October 2026. In addition to standard product specifications, the company offers custom services including specialized high-voltage component design, non-standard insulation formulations, and tailored packaging solutions.
