On March 12, 2021, the relocation and landing project of 330kV overhead transmission line in the northeast of Xi'an – the first circuit Jingbei Ⅱ line was successfully put into operation.

The 330kV 2500mm2 cable accessories are supplied and constructed by our company, including multiple sets of combined premoded joints. This is a major application of the company's independent R & D of high-voltage accessories in national key projects.

The relocation and landing project of 330kV overhead transmission line in Xi'an is a key project to meet the 14th National Games. It is the largest single EHV cable project in China so far, and a breakthrough attempt in the relocation and landing of high voltage overhead transmission lines in the field of power engineering in China. The successful operation of the first circuit is a full demonstration of the company's strong technical R&D strength and construction serviceability. The company will continue to do a good job in the supply and construction of follow-up lines, providing a full guarantee for the full completion of the project.
