UEALINK × United Aircraft Aviation’s Collaborative Case on Lightweight Specialized Wiring Harnesses for Onboard Systems

I. Project Background

United Aircraft specializes in the R&D and manufacturing of complete aerospace systems, industrial drones, and airborne precision electronic control equipment. The operating environment for airborne equipment is extremely harsh, requiring resistance to extreme temperature variations from -60°C to 180°C, high-frequency vibration, and radiation exposure. Conventional cables are prone to aging and cracking, and their relatively high weight can negatively impact aircraft endurance. Moreover, aviation airworthiness certification imposes stringent mandatory standards on cable safety, flame retardancy, and weather resistance.

UEALINK has established a dedicated clean production line for aviation cables, adhering to the AS9100 aerospace quality management system throughout the entire process. This results in lightweight, highly flame-retardant specialty insulated wires, paired with custom-designed airborne wiring harness assemblies, meeting the rigorous requirements of aerospace vehicles for weight reduction, high reliability, and airworthiness compliance.

II. Key Collaboration Data and Outcomes

1. Order and Delivery Data

   Through a long-term framework agreement, UEALINK supports multiple product lines of United Aircraft’s manned aviation equipment and industrial drones. Production of aviation fluoroplastic cables, lightweight silicone cables, and customized airborne wiring harnesses is scheduled flexibly in batches, balancing small-batch prototyping for new aircraft development with large-scale mass production for mature models.

   A dedicated technical liaison team has been set up for aviation projects, ensuring response times of ≤48 hours for drawing and sample approvals. With an ample 55,000㎡ factory capacity, stable long-term supply is guaranteed. Domestic deliveries are made from nearby facilities, while export shipments include full AS9100 certifications and third-party airworthiness test reports, ensuring no delays in order fulfillment.

2. Quality and Compliance Performance

   All products comply with the AS9100 aerospace quality management system. They feature XLPE irradiation-crosslinked insulation, covering a temperature range of -60°C to 180°C, and exhibit high flame retardancy, low smoke, halogen-free properties, as well as resistance to vibration and radiation. Lightweight fluoroplastic cables, high-temperature-resistant silicone rubber cables, and custom wiring harness assemblies tailored for airborne electronic control equipment are available.

   The factory holds AS9100 aerospace quality system certification, and each batch of cables and harnesses is accompanied by third-party test reports verifying resistance to high and low temperatures, vibration aging, and flame retardancy. Incoming material inspections and finished-product reliability tests achieve a 100% pass rate, with no incidents of insulation failure or signal interference across bulk shipments.

3. Quantified Value of Supply Chain Collaboration

   ① Dramatically improved operational reliability of airborne equipment: Cables operate stably in extreme environments ranging from -60°C to 180°C, reducing cable-related failures by 90%;

   ② Enhanced aircraft weight reduction and endurance: Thanks to the lightweight cable design, the total wiring weight per airborne device is reduced by 12%, boosting overall aircraft endurance by 8%;

   ③ 100% pass rate in airworthiness testing: Cables fully meet stringent aviation safety standards, enabling airborne equipment to pass all relevant airworthiness tests on the first attempt without any need for rework;

   ④ Reduced lifecycle costs of equipment: With excellent radiation resistance and aging durability, the replacement cycle for entire sets of cables is extended threefold, cutting overall lifecycle maintenance and operating costs by 55%.

III. Significance of the Project Collaboration

In this collaboration, UEALINK strictly adhered to the highest aerospace safety and weight-reduction standards, comprehensively addressing all requirements of United Aircraft’s airborne equipment—extreme environmental resilience, weight reduction and endurance, airworthiness compliance, and long-term stability and reliability. This enabled integrated delivery of specialized aviation cable R&D, custom wiring harness assembly, and complete aviation qualification documentation, achieving zero quality incidents throughout the entire process. Leveraging this benchmark case in the aviation sector, UEALINK has successfully expanded its customer base to include leading clients across five major industries—energy storage, automotive, medical, industrial automation, and aviation—thereby further enhancing its one-stop specialized wiring harness support capabilities across the entire industry.
