Prostar Rail Transit UPS Power Solution Safeguards Yiwu Shangcheng Avenue Tunnel

Release Date:


The Yiwu Shangcheng Avenue Tunnel project stretches from Xuefeng East Road in the west to the east of Zhejiang Hospital Fourth Branch, with a total length of approximately 6.04 kilometers. It adopts an underground tunnel combined with surface road construction, following the standards of a city's main road. Both the underground tunnel and surface roads are designed with dual six-lane configurations, allowing for a maximum speed of 60 km/h. The entire route includes 10 entrance and exit ramps, 6 underground connecting passages (including a future right-turn over the river), as well as 1 management facility and 2 ventilation towers. The project will add approximately 194,656.5 square meters of additional land after completion.



Recently, Prostar Rail Transit dedicated UPS power supply has been deployed to protect the Yiwu Shangcheng Avenue (Xuefeng East Road to Zhejiang Hospital Fourth Branch) tunnel, providing reliable power support for its operations including power supply, lighting, ventilation, monitoring systems, fire systems, and other equipment.


In order to meet the power supply requirements of the Yiwu Shangcheng Avenue (Xuefeng East Road to Zhejiang Hospital Fourth Branch) tunnel, Prostar has tailored an electricity assurance system specifically for its power system. Multiple sets of rail transit dedicated UPS power systems have been deployed throughout the tunnel, ensuring high-quality and reliable power supply to guarantee the flawless operation of the equipment in the Yiwu Shangcheng Avenue (Xuefeng East Road to Zhejiang Hospital Fourth Branch) tunnel.


For this project, Prostar has implemented the Rail Transit UPS power solution, which scientifically and reasonably addresses the power supply, monitoring system, lighting, and fire facility's electrical safety concerns. The solution provides outstanding qualities such as high efficiency, high power factor, and high power density to the power system, receiving high recognition from the customer.
