About Sanqing Internet Technology

Beijing Sanqing Hulian Technology Co., Ltd., also known as Sanqing Interconnection, is a national high-tech enterprise specializing in the power Internet of Things (IoT). Founded in 2011 by Hu Jiani, the company operates as a provider of key technologies, core intelligent equipment, and services for the power IoT sector in China. The company leverages its connection with Tsinghua University, relying on the research and talent from the institution to drive its product development.

The current actual controller of the company is Wei Wenhui, who holds a Ph.D. from Tsinghua University and previously worked at the State Grid Corporation of China for 12 years before joining Sanqing Hulian as general manager in late 2016. His transition into the company marked a significant turning point, leading it into a period of rapid growth. Sanqing Hulian submitted an application for an IPO on the Shenzhen Stock Exchange's ChiNext board in September 2023, planning to raise 340 million RMB. However, the IPO process was later terminated.

Sanqing Hulian's business focuses on intelligent power distribution and transmission, offering products and solutions that support the construction of interconnected and intelligent power grids. Its main product line includes intelligent sensors, smart terminals, and intelligent control devices such as fault indicators, online monitoring sensors for partial discharge, and integrated primary and secondary circuit breakers and ring network cabinets. These products have been deployed in nearly 30 provinces across China, including Jiangsu, Zhejiang, and Shandong. The State Grid Corporation of China has historically been a primary client. Following the acquisition of equipment manufacturer Keruina in 2020, the company expanded its client base to include other electrical equipment manufacturers.

The company's business model is centered on the research, development, production, and sale of these power IoT devices. It has secured multiple rounds of financing, including a Series C round of several hundred million RMB in January 2026, co-led by Fosun Chuangfu and October Capital.
