On June 10, the Hami–Chongqing ±800kV ultra-high-voltage direct current (UHVDC) transmission project — a key component of China's national energy strategy — was officially put into operation. As one of the 102 major projects outlined in the 14th Five-Year Plan and a vital part of the "Xinjiang electricity to Chongqing" initiative, the project plays a significant role in advancing China’s clean energy goals and contributing to the realization of its "dual carbon" targets.

As a leading domestic developer of power electronic components, Sun. King Technology has provided robust technical support to this "energy superhighway" through its advanced anode saturated reactors, power capacitors, and online monitoring solutions — all known for their strong R&D foundation and superior product quality.
