DONGGUAN, CHINA – October 21, 2026 – Dongguan UEALINK Electronics Co., Ltd., a global provider of high-end cable connection system solutions, today announced its full portfolio of IATF16949 certified automotive wire harness and high-voltage cable assemblies is available for global enterprise customers. The product line is designed to solve core pain points including in-vehicle insulation failure under extreme temperature and vibration, multi-vendor supply coordination complexity, and heavy conventional harness weight that reduces driving range. Built with 1000V DC withstand capability, oil and hydrolysis resistance, and flame retardant properties, the portfolio supports one-stop integration of charging gun components to simplify customer supply chains. The company aims to expand its global footprint in the automotive connection segment by providing compliant, high-reliability solutions for new energy vehicle and charging infrastructure operators. The full product line is now accepting global orders, with mass production and worldwide shipping already active for qualified enterprise customers.
The automotive wire harness portfolio is built to address core pain points of global new energy vehicle and charging infrastructure operators, with four key differentiators:
1. Vehicle-grade high voltage performance: All cables support 1000V DC withstand voltage, with oil resistance, hydrolysis resistance, flame retardant and explosion-proof properties, adapted to extreme in-vehicle temperature ranges and long-term vibration conditions to eliminate insulation failure risks.
2. Integrated one-stop supply: The product line covers high-voltage cables for battery packs, PDU connections, charging cables, and integrated charging gun high-voltage components, eliminating the need for multi-vendor coordination and reducing delivery synchronization risks.
3. Lightweight design: Optimized cable structure reduces overall harness weight by 25% compared to conventional equivalent products, supporting vehicle lightweight requirements to extend driving range.
4. Proven field performance: The harnesses have been deployed in mass production for leading new energy vehicle manufacturers, with zero failure in high-low temperature and collision durability tests, and a 68% reduction in vehicle high-voltage system fault rates.
To meet global market access requirements, the full automotive wire harness line is manufactured under the IATF16949 automotive quality management system, with product-level certifications including CCC, UL2263, and TUV. The company also holds ISO9001, ISO14001, ISO13485, AS9100, and SA8000 management system certifications, and maintains one of the most comprehensive UL certification portfolios for cables in Asia. All products are compliant with RoHS and REACH requirements, supporting smooth customs clearance for exports to the European Union, North America, and other global markets.
The automotive wire harness portfolio is available for global order placement via the company’s official website, with active mass production and worldwide shipping for qualified customers. The company supports both small-batch sample orders for new product development and large-volume mass production for tier-1 automotive suppliers, with a 100% on-time delivery rate for bulk orders. Customization options include tailored cable specifications, high-voltage connection component design, and integrated harness assembly to match specific vehicle model and charging equipment requirements.
