Jiquan ±1100kV UHVDC transmission project is a national strategic key project of the "West-to-East Power Transmission Project", Sunri Zhilian is responsible for installing IOT sensing equipment such as micro-power wireless temperature measurement device in Anhui section of the line to realize real-time sensing and intelligent diagnosis. In order to ensure the stable operation of the main body of the line, Sunri Zhilian’s products have been applied to the transmission line with the highest voltage level in China.

The line passes through Nanchang, Fuzhou and Yichun of Jiangxi Province and Changsha of Hunan Province, and Sunri Zhilian provides the fault monitoring solution for the Grade-3 galloping area of the line. With profound technical background and positive response speed

Sunri Zhilian is responsible for providing the integrated solution to the IoT sensing system  of the 500kV Su'ai Line. The device can monitor the data such as transmission line conductor temperature, conductor vibration, tower tilt, environmental micro-meteorology, etc. It has been successfully connected to the background of the power intranet, which will make the transmission management mode smarter, more efficient and safer

This project is located in Xiamen, Fujian Province, for which the online monitoring equipment is installed on the 110kV line Lilin - Yannei π to Pubian Substation, and Zhuhai Sunri Zhilian Technology provides the integrated online monitoring solution. Faced with great construction difficulties and high standard delivery requirements, Sunri Zhilian, based on its strong R&D technology accumulation and perfect project management mechanism, ensured the smooth delivery and acceptance of the project and provided the user with integrated cable monitoring services.

The project is located in Shenzhen, Guangdong. From 2015 to 2017, CYG Sunri had delivered dozens of online monitoring devices for cable grounding circulation, which are applied to variousscenarios such as engineering wells, tunnels, indoor substations, outdoor substations, etc.

As a secondary equipment integrator, Sunri has completed the secondary system integration of two 220kV and eight 110kV booster stations at the same time, providing 401 panel cabinets, more than 1,000 sets of equipment and 27 sets of prefabricated cabins for secondary and communication equipment, effectively saving the construction period and helping the power station to be connected to the grid.

Located at the Data Processing Center of Shanghai Rural Commercial Bank in Pudong Financial Center, Shanghai, this project covered an area of 6,000 m2, with an installed capacity of 495kW. CYG SUNRI provided overall EPC solution for this project.

CYG Sunri cooperated with Wanyu Sanxin Electronics (Dongguan) Co Ltd. to build a 2MW/5MWh user-side energy storage system at the open space in the park through contract energy management. This project adopts an integrated solution of energy storage cabin

On the basis of the construction experience of several intelligent substation projects, CYG Sunri has fully analyzed the pain points and difficulties in the construction of intelligent operation and maintenance system, creatively explored and implemented the scheme based on the needs of operation and maintenance system
