As HT Aero’s “Land Aircraft Carrier” flying car and EHang’s EH216-S autonomous passenger electric vertical takeoff and landing (eVTOL) aircraft took center stage at the Canton Fair Complex, countless precision connectors and wiring harnesses were defining the reliability and intelligence of future air mobility behind the scenes. From December 12 to 14, 2025, the 2025 International Low-Altitude Economy Trade Expo (Guangzhou) & 8th Global Unmanned Systems Conference, themed “Innovate Low-Altitude, Serve Global Trade”, grandly kicked off. This industry gala, gathering over 350 industrial chain enterprises worldwide and covering full-chain segments including eVTOLs, unmanned aerial vehicles (UAVs), and low-altitude intelligent connectivity, not only demonstrated the vibrant momentum of low-altitude economy evolving from “conceptual blueprint” to “systematic implementation” but also clearly outlined the core directions of industrial technological innovation and commercialization. As the “neural hub” for the safe and efficient operation of low-altitude equipment, precision connectivity technology is now facing unprecedented development opportunities.

The Expo Kicks Off: Low-Altitude Economy Enters the Eve of Accelerated Industrialization

Against the backdrop of the 15th Five-Year Plan proposal designating low-altitude economy as a strategic emerging industry, this Guangzhou Low-Altitude Expo holds landmark significance, serving as a vivid microcosm of the rapid rise of China’s low-altitude economy. National policies continue to ramp up support, with nearly 30 provinces (autonomous regions, municipalities directly under the Central Government) having issued relevant supportive measures. The industry generally predicts that by 2035, the market scale of China’s low-altitude economy is expected to exceed 3.5 trillion RMB.

As a national low-altitude economy industrial hub, Guangdong fully demonstrates its “leading goose” role. Data shows that Guangdong is home to over 15,000 relevant enterprises (accounting for more than 30% of the national total), with 2024 output value exceeding 180 billion RMB. Among these, consumer-grade UAV production accounts for 70% of the global market, and industrial-grade UAV production accounts for 50% of the global market, showcasing significant market share advantages. At this expo, 255 Guangdong-based enterprises and institutions (over 70% of total exhibitors) participated; leading enterprises such as HT Aero, EHang, and DJI showcased cutting-edge equipment, while over 20 concurrent thematic forums delved into core topics including eVTOL technological innovation, low-altitude intelligent network construction, and industrial globalization. More encouragingly, over 10 enterprises signed on-site agreements during the expo, with a cooperation scale exceeding 3 billion RMB covering multiple dimensions such as aircraft procurement and platform co-construction—indicating that industrial collaboration and commercial implementation are accelerating.

From the core signals conveyed by the expo, competition in the low-altitude economy has extended from whole-machine manufacturing to the upstream core components sector. Lightweight, intelligent, and high-reliability equipment have become core demands for industrial upgrading, which in turn impose more stringent technical requirements on upstream core components. Among these, connectors and wiring harnesses—key components ensuring power transmission and signal interaction for low-altitude equipment—directly determine the flight safety, endurance, and operational stability of the equipment.

Trend Insight: From “Taking Off” to “Flying Steadily”, Connectivity Technology Becomes a Core Pillar

Across expo forums and exhibits, the industry has reached a core consensus: the success of low-altitude economy lies not only in building sleek aircraft but also in constructing a complex ecosystem that ensures its normalized, large-scale, and safe operation. Behind this lies three core challenges for connectivity technology, which are also key pain points of concern across the industrial chain:

1. High-reliability power transmission challenge: Equipment such as eVTOLs and industrial UAVs have extremely high requirements for power system stability. Especially during vertical takeoff and landing, batteries need to output extremely high power—corresponding high-voltage connectors must have excellent high-voltage resistance and arc resistance, while adapting to a wide temperature range of -40°C to 125°C to ensure continuous and stable power transmission, avoiding flight accidents caused by connection failure.

2. Signal integrity challenge in harsh environments: Aircraft face severe vibration shocks, wide temperature fluctuations, and complex electromagnetic environments. Massive data between flight control systems, navigation sensors, and communication modules requires real-time, lossless interaction. This demands connectors with high protection ratings and electromagnetic interference (EMI) resistance; precise shielding design ensures accurate signal transmission, safeguarding the “brain”and “senses”of flight decision-making.

   

3. Lightweight and customized adaptation challenge: To improve range and payload, aircraft have near-stringent weight reduction requirements. Connectors need to evolve toward high-density, miniaturization, and lightweight design. Meanwhile, structural layouts vary significantly across different equipment types (UAVs, eVTOLs, low-altitude logistics equipment), requiring wiring harnesses to have high customization capabilities. By optimizing wiring design and material selection, a perfect balance between weight reduction, reliability, and maintainability can be achieved.
