Case
Yunnan Yunfeng Expressway
The starting point of the Yunxian to Fengqing Expressway is located near Fengwangzhai on the west side of Yunxian County Town, connecting with the planned G5612 Yunxian to Lincang section expressway and G5612 Nanjian to Yunxian section expressway at the Pingzhang hub interchange, and the endpoint is at the junction of Fengqing and Changning counties (Xinxin Village on the east slope of Changning River), seamlessly connecting to the Fengqing to Changning to Baoshan expressway.
Recently, Baoxing Rail Transit EPS power supply has been guarding the Yunfeng Expressway, providing reliable power support for its power supply, lighting, ventilation, monitoring system, fire protection system, and other equipment systems.
In order to meet the power supply needs of the Yunfeng Expressway tunnel, Baoxing Group has tailored a power guarantee system for its power system, using multiple sets of EPS fire emergency systems, fully stationed at various important locations in the Yunfeng Expressway tunnel, providing high-quality and highly reliable power supply, ensuring the absolute reliability of power supply for the Yunfeng Expressway tunnel and equipment.
This project adopted the Baoxing Rail Transit EPS power supply solution, successfully solving the power supply, monitoring system, lighting, and fire safety issues of the tunnel through a scientifically reasonable distribution layout. It provides high reliability, high efficiency, high power factor, and high power density, and has received high recognition from customers.
