DONGGUAN, China – October 9, 2026 – Dongguan UEALINK Electronics Co., Ltd., a global provider of high-end cable connection system solutions, today announced the launch of an upgraded custom automotive wire harness product line. Designed to address core pain points of new energy vehicle (EV) and charging infrastructure manufacturers, including high-voltage safety, lightweight design and automotive-grade compliance, the line features high-voltage tolerance, high flexibility and full international certification coverage. Through this launch, the company aims to provide global EV manufacturers with a reliable Chinese supply chain option, expanding its footprint in the global EV connection solutions market. The enhanced product line is now available for global order placement via the company’s official website, with mass production already underway to support existing and new client demand.
The upgraded automotive wire harness line delivers four core value propositions for global clients:
1. Automotive-grade high-voltage performance: Rated for 1000V DC operation, the cables withstand -40℃ to 150℃ temperature extremes, constant vibration, oil exposure and hydrolysis, with flame-retardant and explosion-proof properties to support high-power transmission for onboard battery packs, power distribution units and charging piles. Field deployment with BYD has shown a 68% reduction in vehicle high-voltage system failure rates, with zero cable failures during crash and extreme temperature endurance testing.
2. Lightweight integrated design: The harness assembly reduces total weight by 25%, supporting an average 6km range improvement for mainstream EV models. The line includes integrated charging gun and high-voltage terminal components for one-stop assembly, eliminating multi-supplier coordination delays, with 100% on-time delivery for bulk orders.
3. High flexibility for automated assembly: Cables feature a bending radius of only 4-5 times their outer diameter, compatible with automated wire harness processing equipment. This reduces bending processing time by 32% and increases single production line daily output by 28%, compared to traditional rigid cables.
4. Full-process quality traceability: All materials are tracked from incoming inspection to final shipment, with 100% outgoing testing that improves inspection efficiency by 20% for automotive clients.
To meet global market access requirements, the automotive wire harness line is fully aligned with IATF16949 automotive quality management system standards, with products holding CCC, UL2263 and TUV automotive-grade certifications. The company also maintains IECQ QC 080000 hazardous substance process management certification, meeting EU RoHS and REACH regulatory requirements. This full compliance portfolio supports customs clearance and customer audit requirements across North America, South America and Eastern Europe, with a 100% first-time pass rate for overseas project qualification reviews.
The upgraded automotive wire harness line is available for global order placement via the company’s official website, supported by a 55,000-square-meter production base. The company accommodates both small-batch prototyping for new product development and large-scale mass production for commercial vehicle programs. Beyond standard products, the company provides custom services including specialized insulation material selection, non-standard high-voltage connection component molding, and cable structure optimization for specific onboard operating conditions.
“The launch of our enhanced automotive wire harness line reflects our long-term commitment to solving global EV manufacturers’ core pain points around supply chain reliability, compliance and lightweight design,” said You Zibiao, Head of Global Business at Dongguan UEALINK Electronics Co., Ltd. “As one of the Chinese suppliers with the most comprehensive UL-certified cable portfolios in Asia, we are positioned to support global clients with stable, cost-effective connection solutions that reduce supply chain disruption risks.”
The global growth of the EV market has driven rising demand for high-voltage wire harness solutions, with supply chain reliability and compliance emerging as top priorities for global vehicle manufacturers. Dongguan UEALINK Electronics’ expanded automotive wire harness capacity aligns with this trend, as the company currently generates 18% of its revenue from North American clients, 16% from South American clients and 8% from Eastern European clients, with a growing global footprint to support cross-border manufacturing partnerships.
