Industrial-grade heavy transport platforms built to direct IATA airport handling standards.
In contemporary aviation ecosystems, the efficiency of ground operations directly dictates the turnaround time (TAT), operational safety, and overall decarbonization capability of airlines and airport hubs. At the center of this paradigm is the Ground Power Unit (GPU), an essential electrical system designed to provide continuous, high-fidelity 400Hz AC and 28.5V DC electricity to aircraft while parked on the apron. This eliminates the reliance on auxiliary power units (APUs), substantially cutting fuel emissions and maintenance overheads.
As a leading Chinese manufacturer, our factories integrate next-generation solid-state frequency converters, smart PLC-controlled diesel generators, and eco-friendly lithium iron phosphate (LiFePO4) battery systems to align with the aviation sector's net-zero transition. By delivering high structural stability, optimal voltage regulation, and precise wave filtering, our products safeguard complex avionics suites across all civil, cargo, and defense airfields globally.
Why Tier-1 airlines and global airport authorities source their GSE from our state-of-the-art Chinese production lines.
Our units utilize dynamic solid-state technology built with premium IGBT modules. This translates to incredibly low harmonic distortion (THD < 2%) and faster transient response times, protecting modern fly-by-wire aviation electronics from voltage drops or surges.
Engineered for high resilience, our GPUs operate flawlessly in extreme climates ranging from -40°C Siberian winters to +55°C Middle Eastern deserts. Dual-layer anti-condensation structures and IP55-rated enclosures shield active electronics from humidity, dust, and sand.
All manufactured systems strictly satisfy standardizations, including ISO 6858, EN 12312-20, SAE ARP 5015, and Mil-Spec parameters. We ensure your ground crews operate under secure CE and TUV certified configurations.

Global aviation regulators, including the FAA and EASA, are continuously tightening emissions limits within airfield boundaries. Traditional diesel-powered GSE is being actively replaced with electric Ground Support Equipment (e-GSE). Our research and development center focuses heavily on battery storage towable ground power units, which deliver peak performance without regional emissions.
Furthermore, cloud-based telemetry is now a baseline requirement for major fleet managers. Our units feature active IoT modems that stream live data—such as fuel usage, battery health indices (SOH), temperature profiles, and output wave metrics—to central management systems. This empowers airports to implement preventive maintenance structures, minimizing costly downtime during peak arrival waves.
We design complete, modular solutions for various airport operation profiles:
Static, bridge-mounted solid-state GPUs linked to central 400Hz ring main units for uninterrupted power supply.
Mobile diesel or high-capacity battery units designed for rapid deployment across remote stands.
Military-grade customized GPUs complying with electromagnetic compatibility (EMC) guidelines.
Ensuring stability, longevity, and professional collaboration across global supply networks.
Our company focuses on advanced product design and proactive research and development, utilizing state-of-the-art technologies and specialized innovations directly at the factory level.
High-quality, reliable units designed to meet the exact operational demands of end users, standing out in competitive global landscapes and earning long-term market trust.
Through robust supply chain logistics, managed parts inventory, and dynamic freight management, we ensure prompt manufacturing and on-time shipment arrival.
No two airports operate under identical rules. Differences in airfield layouts, ground power connection angles, grid voltages, and local compliance requirements demand highly customizable engineering. We supply a comprehensive suite of OEM and ODM services, catering to tailored designs for specialized ground support machinery.
Our design process integrates 3D modeling and structural finite element analysis (FEA) to confirm chassis strength, weight distribution, and thermal profiles. Whether you require custom paint schemes, tailored plug configurations, dual-voltage outputs (simultaneous AC & DC), or specialized towable hitches, our manufacturing lines adjust rapidly to custom specifications.
