The first high-voltage direct current (HVDC) transmission line in Pakistan, is the transmission line with the highest voltage level, the longest transmission distance and the largest transmission capacity within Pakistan.

This project is the first direct - current transmission project in Turkey. It effectively improves the reliability of local residents' electricity supply.

Invested by Tennet, this project is key to Germany's energy shift. Set to commission in late 2027, it applies ±320 kV tech with 980 MW capacity, enhancing offshore wind power transfer and refining the energy mix.

The control equipment for UHV DC transmission converter valves based on the domestic chip VCE800G has been developed, which provides reference and demonstration for the transformation of several important EHV converter stations in the future.

This project is the offshore wind power flexible DC transmission project with the largest transmission capacity in the world. It is also the first application of flexible DC transmission technology in offshore wind power in Asia.

This project can transmit over 30 billion kilowatt-hours of electricity annually. The utilization of clean hydropower will reduce the consumption of 10.57 million tons of coal and the emission of 19.19 million tons of carbon dioxide.

The world's first ±500 kV/1500 MW flexible DC converter valve suitable for flexible DC power grids, developed by XJ, has been successfully applied in the Zhangbei Flexible DC Power Grid Test and Demonstration Project.

This project is the world's first UHVDC project that adopts the hybrid cascaded converter technology. After it was put into operation, it can reduce coal transportation by 13.75 million tons every year, and cut carbon dioxide emissions by 27 million tons and sulfur dioxide emissions by 68,000 tons.

This is the world's first ultra-high voltage multi-terminal hybrid DC transmission project. The highest daily power transmission of this project reaches 192 million kilowatt-hours.
