Explore our primary range of custom-engineered GSE solutions, certified to withstand rigorous airport operational environments globally.
The international aviation sector is undergoing a massive shift towards ecological transition, driven by international policies like the IATA Net-Zero 2050 target and local airport emission guidelines. Ground Support Equipment (GSE), specifically Ground Power Units (GPUs), plays an essential role in this transformation. By supplying stable, 400Hz AC or 28.5V DC electric power directly to parked aircraft, GPUs enable airlines to shut down auxiliary power units (APUs), drastically reducing jet fuel consumption, minimizing ramp noise pollution, and limiting localized greenhouse gas emissions.
Currently, airports worldwide are modernizing their infrastructure to incorporate either static ground power units directly integrated into boarding bridges or deploying highly mobile solid-state towable units. Chinese manufacturers have established themselves as pivotal suppliers in this ecosystem. Benefiting from a robust supply chain, rapid advances in power electronics (such as silicon carbide IGBT technology), and lower assembly overheads, factories in China are offering heavy-duty GPUs that meet or exceed international standards like ISO 6858, EN 12312-20, and MIL-STD-704F.
Operating an aircraft's jet-fuel-powered APU during ground turnarounds can cost airlines hundreds of dollars per hour in maintenance and fuel. Implementing a high-efficiency solid-state ground power supply reduces operational costs by up to 85%, creating a rapid return on investment (ROI) within 12 to 18 months.
Environmental regulations now penalize excessive ground engine runtimes. Aerotropolis nodes in the EU, North America, and East Asia are offering preferential slotting or reduced airport landing fees to airlines utilizing advanced green ground support systems.
Understanding the strict power quality requirements of commercial and military aircraft is essential for procurement managers. Below is the technical specification breakdown for our primary aircraft ground power solutions.

Ground support equipment must perform consistently across diverse microclimates. China manufacturers have engineered specialized chassis configurations and cooling mechanisms to address these localized challenges:
In cold regions like Northern Europe, Canada, and Northern China, extreme cold leads to battery degradation and fluid freeze. Our systems integrate smart thermal management units (glycol heating loops) that preheat electronic enclosures and keep battery packs within optimum operating temperature thresholds, working alongside advanced cabin heaters.
Marine environments present corrosion risks. To prevent PCB failure, our solid-state GPUs feature double-sided conformal coatings, marine-grade powder-coated steel or aluminum enclosures (IP55/IP65 ratings), and stainless steel fasteners designed to resist humidity and salt spray over decade-long lifespans.
Thin air at high elevations compromises convection cooling and electric insulation properties. Chinese engineering customizes converter modules with oversized heatsinks and forced liquid cooling systems, adjusting dielectric spacing to prevent electrical arcing at low atmospheric pressures.

The future of airport ramp services points toward automation, smart grids, and hybridization. Over the next decade, ground power setups are expected to integrate closely with local airport microgrids. Key developments include:
Silicon Carbide (SiC) semiconductors replace traditional Silicon IGBTs, enabling higher switching frequencies, lower operating temperatures, and higher conversion efficiencies, resulting in smaller footprints.
Battery-driven GPUs serve dual purposes: acting as backup power sources during peak grid demand and storing excess solar energy generated by airport terminal building roofs.
Integrating LiDAR and GPS positioning into towable GPUs allows units to navigate autonomously from charging bays to assigned gates, minimizing crew requirements and ramp accidents.
Our goal is to deliver long-term value, offering durable ground support equipment for commercial airlines and logistic operators globally.
