Wieland Supplies Power Bus System For New Beijing Daxing Airport In China


Some 50 kilometers south of the center of Beijing, work is ongoing on the first phase of the construction of Beijing Daxing International Airport, which is set to be completed this fall with a capacity of 45 million passengers per year. When the final phase of the construction has been completed, the airport will have eight runways and the ability to accommodate up to 130 million passengers. With such a high number of travelers, the demands on the baggage sorting operation will be high. Its automation is in the hands of Civil Aviation Logistics Technology (CALTCO), a subsidiary of the Civil Aviation Group. The Chinese equipment supplier is keen to implement a solution for distributing energy to the baggage sorting system that is as easy as possible to install and requires little maintenance, and that is why it opted for the podis® power bus system from Wieland Electric.

With its long-standing experience and numerous international references in airport logistics, Wieland was again able to convince those responsible for this particular project of the advantages of the flat cable system. With the decentralized approach, the electrical supply is easy, quick, and safe to install in a highly structured manner, which is especially suited to expansive systems. Some 31 kilometers of podis® 7G4 flat cable, 750 distribution modules, and 5,700 connection modules will be used for the baggage sorting system at Beijing Daxing Airport. Compared with conventional plumbing and wiring systems, Wieland’s modular power bus system enables not only flexible cabling but also extremely short installation and commissioning times with savings of 70 percent on time and 30 percent on costs. This is thanks to the industrially prefabricated and tested components, which are simply plugged together on-site.

What is more, the podis® power bus also renders the operation of systems virtually maintenance-free. Connection is established using insulation-piercing contacts. Once installed, this type of connection is maintenance-free for the entire life of the system. Due to the system concept, taps can be positioned without making any mistakes, removing the need for further checks. So, in addition to the considerable savings during installation, this also means further savings on labor, time, and costs. Thanks to its international certifications, the flat cable system is ideal for use worldwide and meets all the requirements here in terms of product and assembly approvals.
