Weihai Guangtai GPU

The Weihai Guangtai GPU (Ground Power Unit) is a mobile electrical supply system designed to provide 400Hz AC and 28V DC power to aircraft while stationary on the tarmac. Manufactured by Weihai Guangtai Airport Equipment Co., Ltd. , these units are part of a broad portfolio of ground support equipment that has expanded from domestic Chinese production to a global export presence. The units are available in towable or self-propelled configurations, using diesel engines or battery-electric drivetrains to power aircraft avionics and systems without depleting onboard batteries or running the Auxiliary Power Unit. Primary buyers include international commercial airports, ground handling service providers, and major airlines seeking to reduce fuel consumption and noise pollution at the gate. The product is sold through regional distributors and direct government procurement tenders. Known operators include major Chinese hubs such as Beijing Capital and Shanghai Pudong, while the manufacturer maintains a presence in Southeast Asia, the Middle East, and parts of Europe through its international sales network. The equipment is compatible with a wide range of narrow-body and wide-body aircraft types. From a procurement perspective, the primary risks involve the long-term availability of specialised replacement parts outside of the Asia-Pacific region and the local emission compliance of the diesel variants. The Aerospace Garage desk would verify the specific noise level certifications for European or North American operations and check the lead times for service technicians in the buyer's territory. Furthermore, buyers should confirm the integration compatibility of the digital control systems with existing fleet management software used by ground handlers.
