Recently, from the TBEA Hengyang Transformer Co., Ltd. came good news, the company independently developed and manufactured in Anhui East to send 1000MVA / 1000kV UHV transformer a successful test, the technical indicators are better than the technical agreement, will serve the first A UHV AC double-circuit transmission project on the same tower Anhui to Huainan to Shanghai UHV AC transmission demonstration project. Anhui East to send 1000MVA / 1000kV UHV transformer is running the world's highest voltage level, the largest capacity of the autotransformer, on behalf of the transformer manufacturing industry's leading technology. This product has high voltage level and large product capacity. It is one of the key equipment for AC UHV transmission network. Its successful development will provide a powerful guarantee for building a nationwide transmission network and realizing energy transmission across regions, long-distance and large-capacity. At the same time, it also greatly enhanced the research and development of UHV transformers for the Company and laid a solid foundation for the subsequent development of the Company. It is understood that the project of sending power from Anhui to the east is the second UHVAC transmission project following the first UHV AC pilot demonstration project (Jindongnan Nanyang Jingmen) in our country and is a landmark project of large-scale application of UHV AC power transmission and transformation technology It is also a major project of UHV exchange under key national grid construction during the 12th Five-Year Plan period. It is a world-class major innovation project.
