Since the 66kV cable terminal that Guolian put into operation in Fuxin Power Plant in 2002, Guolian has continued to provide stable and reliable products for power grid, energy and chemical industry, rail transit and other important industries, and has become a supplier of power products in the whole link of power generation, transmission, transformation, distribution, electricity consumption and so on.

In 2006, the renewable energy law came into force, officially starting the development of renewable energy. In 2007, the national development and Reform Commission issued the medium and long term development plan of renewable energy, ushering in the golden period of China's wind power industry. Guolian cable accessories provided cable accessories products and installation technical services for wind power projects such as CPI, Datang, Huaneng and Huadian from 2008 to 2012. So far, these projects have operated safely for more than 10 years.

In 2010, the State Grid Corporation of China began to conduct centralized bidding and procurement of 110kV cable accessories, and Guolian won the bid continuously, becoming the supplier of cable accessories of the State Grid.
