SINNHONG Expanding High-Voltage eVTOL Harness Production in Vietnam to Support 2026 Global UAM Infrastructure

As the Urban Air Mobility (UAM) sector enters its commercialization phase, SINNHONG, a premier IPC-A-620 certified partner for OEM Electronics Manufacturing, has announced a strategic capacity expansion at its Ho Chi Minh City facility. The move is designed to meet the skyrocketing demand for High-Voltage eVTOL power distribution harnesses and BVLOS-compliant signal cabling from North American and European aerospace OEMs.

Technical Breakthrough: Powering 800V eVTOL Architectures

With the 2026 shift toward larger, passenger-carrying autonomous aerial taxis, traditional drone wiring is being replaced by sophisticated aerospace-grade interconnects.

"We are tracking a significant increase in Google searches for '800V eVTOL power harness' and 'IPC-A-620 Class 3 UAV wiring,'" said SINNHONG’s Strategic Marketing Manager. "Our Vietnam facility is now optimized for these high-power density requirements. By using UL Listed Teflon and Silicone-insulated wiring, we ensure thermal stability for high-current ESC to motor links, even in the most demanding flight duty cycles."

Supply Chain Resiliency: The Section 301 Tariff Solution

The geopolitical landscape of 2026 has made "China Plus One" sourcing a necessity rather than an option. With Section 301 tariffs on Chinese electronics remaining a major cost driver, SINNHONG’s Vietnam-based production offers a critical tariff-exempt sourcing route.

"B2B procurement officers are now searching for 'Landed-cost optimized UAV interconnects' to protect their margins," the manager added. "Our Ho Chi Minh City plant allows global partners to benefit from duty-free imports into the U.S. and EU markets, combining SINNHONG’s China-based R&D excellence with the strategic economic advantages of Vietnam manufacturing."

Future-Ready Interconnects for Autonomy

The new 2026 production lines at SINNHONG are also tackling the challenges of BVLOS (Beyond Visual Line of Sight) and Remote ID compliance:

• EMI Shielded Twisted Pairs: Specifically designed to protect GPS and Magnetometer signals from high-frequency motor interference.

• IP68 Overmolded Assemblies: Providing ruggedized protection for agricultural spraying drones and maritime UAVs operating in corrosive environments.

• Low-Latency Fiber Optics: Enabling 8K real-time LiDAR point cloud transmission for advanced infrastructure mapping.
