EAST intelligent power supply helps Changli Expressway to be completed and opened to traffic

On September 26, after three years of construction, the Changzhou-Liyang Expressway was officially opened to traffic. The entire expressway uses the aerospace-quality intelligent UPS power supply solution of East Group, providing high-quality and efficient power supply guarantee for its future stable operation.

The Changli Expressway, with a total investment of 2.814 billion yuan, is 38.4 kilometers long. This spacious, smooth and high-quality expressway is built according to the standards of a two-way four-lane expressway with a design speed of 120 kilometers per hour. It starts from 2.55 kilometers west of the Jiaze Interchange of the Yanjiang Expressway in the north and ends at 1.53 kilometers north of the Xinchang Hub of the Yangli Expressway in the south. The route as a whole passes between Provincial Highway 239 and Changdang Lake. There are 5 interchanges and 2 hubs along the entire line. This new traffic fast channel in southern Jiangsu has added a "fast lane" to the development of the regional industrial economy and the industrial economy of the road crossing, forming a new pattern that connects the regional economy, tourism, culture, ecology and other resources along the route.

In order to fully cooperate with the construction of Changli Expressway, EAST dispatched a professional technical team to provide the best solution for the selection of power supply and other equipment for the expressway. After fully considering the complex geological conditions and climatic conditions of the expressway, the EAST technical team provided the expressway with a high-quality digital double-conversion power frequency EA880 series UPS power supply solution. In the end, with the high quality and high reliability of the product and EAST's fast customer service system, the power supply solution successfully won the bid and provided power supply guarantee for the communication, monitoring, and toll collection systems of the entire Changli Expressway project.

EA880 digital double conversion power frequency UPS power supply is a new generation of intelligent power frequency uninterruptible power supply developed with brand-new digital technology to meet the high reliability requirements of power supply systems in China's power grid environment and transportation fields. The system integrates high-performance full digital control, double conversion online structure, input power factor correction, advanced DSP control technology, perfect protection measures, super network management, reasonable human-computer dialogue interface and other sophisticated and mature designs. At the same time, the system can also remotely monitor and manage UPS through remote network monitoring, truly achieving unattended operation. Its superior product performance has been highly praised by highway users.

As an outstanding listed company in the global energy internet system solution and a leading enterprise in the domestic UPS industry, EAST's aerospace-quality series of power supply solutions have been widely used in highways and rail transit fields around the world, and it is also the preferred brand for key highway power supply procurement projects in various provinces and cities. The successful service of the Changli Expressway construction is another victory for EAST Group in serving highways, which once again demonstrates EAST's extensive brand influence and customer trust foundation.
