Alstom Grid is partnering with China Electric Power Equipment and Technology (CET) to develop Ultra High Voltage Direct Current (UHVDC) power transmission systems in China. CET, a wholly-owned subsidiary of State Grid Corporation of China (SGCC), is one of the biggest Chinese utilities. The agreement was signed in a Beijing ceremony and was attended by executives from SGCC, CET, and Alstom Grid

Under the terms of the contract, Alstom reports it will collaborate with CET on “1100 kV and 800 kV converter transformer technology development and manufacture. DC convertor transformer technology, being a core component of the future UHVDC electrical grids, forms an integral part of the research and development project launched by SGCC earlier this year.”

SGCC Executive Vice-President, Cao Zhi’An, explains, “This year marks the starting point for SGCC to begin its large scale HVDC construction projects. SGCC has paid close attention to the cooperation between CET and Alstom in the development of UHVDC converter transformers, and will provide its full support. Meanwhile, I express my sincere wishes to the two companies for the success of this cooperation.”

Grégoire Poux-Guillaume, Alstom Grid President, adds: “The co-development of converter transformers is of strategic importance for both Alstom Grid and CET. Alstom is proud to have this significant R&D cooperation with a subsidiary of SGCC. From co-development to co-production, this agreement will take Alstom’s cooperation with SGCC to new horizons.”

Alstom specializes in HVDC transmission, the fastest growing segment of the high voltage market. Among the company’s projects is a 600 kV Rio Madeira HVDC link in Brazil, which incorporating the world’s longest transmission line at 1475 miles (2,375 km)
