The Dali-Nairobi Expressway Project is a key project of the "three-year action plan" of Chongqing's transportation construction. Weitu Hongda is responsible for the layout of electrical equipment along the line.
The electromechanical system of expressway is distributed along the line and at many points such as toll stations/service areas/tunnels. It is greatly affected by dust/moisture/vibration/impact and high temperature/severe cold and bad weather, which is easy to cause equipment failure. Chongqing is mountainous, and some equipment needs to be installed in mountainous areas. Equipment with outstanding performance indicators is required to reduce maintenance times.




The China Laos Railway starts from Kunming, Yunnan Province, China in the north and ends at Vientiane, the capital of Laos in the south. The whole line adopts Chinese technical standards and consists of Kunyu Section, Yumo Section and Boten Section. The mileage of the line is 400 km, the proportion of bridges and tunnels is 62.6%, and the design speed is 160 km/h. Usually, the travel time from Vientiane to Boten is only 3 hours.
Multinational railways are faced with changeable outdoor environment, and infrastructure plants have higher requirements for stability, durability and reliability of electricity.




Hunish-Serbia Railway is the flagship project of cooperation between China and Central and Eastern European countries. WeituHongda provides power system equipment integration for the railway and provides stable and reliable power supply in the complex transnational power environment.
Multinational railways are faced with changeable outdoor environment, and infrastructure projects require higher stability, durability and reliability of electricity.
With rich project experience, WeituHongda provides online intelligent and fully digital control UPS - WTHD power frequency online UPS, which highly matches the important loads in the project with high adaptability, high reliability and strong protection, and can ensure that the equipment has a continuous and stable power supply even in extreme weather conditions.
