Transmission of long-term commitment to the field of key technologies, processes, equipment, research and development, independent research and development company since 1980 to create the first 220 kV power transformers, the company continue to achieve breakthroughs in technology research and development:

　　In 1997, the first 220 kV 370 000 kilovolt high-capacity power transformer in operation;
　　In 2000, the first 500 kV 167 000 KVA power transformer in operation;
　　In 2009, the first 750 kV 270 000 KVA power transformer through the full test time.
　　September 22, 2011, 1000 kV high-voltage step-up transformer passed all type tests, the transformer industry, research and development to create the shortest, the best performance parameters, "zero-PD" output, successfully tested a new record, achieved "dual-class international and domestic."

1000 kV high-voltage autotransformer, 1100 kV shunt reactors, and ± 800 kV, ± 1100 kV converter transformers are gradually developing.

December 29, 2010, the company backed by China Electric Power Technology Co., Ltd. Ultra high voltage transformer and equipment R & D center was established to further clarify my positioning of the company's future technology: ultra-high voltage AC transformers, converter transformers, shunt reactors devices, smoothing reactors, transformers and other full range of intelligent, full capacity, AC and DC electrical electrical products.

The company has a government subsidy to the State Council experts, leading industry experts, young technical staff as the main R & D team, R & D 147, excellent talent pool for the company's continued technological innovation has laid a solid foundation. Company's total patent and utility model received dozens of patents, has been identified as high-tech enterprises in Shandong Province, Shandong Province Enterprise Technology Center, is a branch of China Electric Industry Association, director of the transformer unit.

Research Institute of Chinese companies rely on smart grid, enhance well-known universities at home and abroad, the world's top transformer Institute (such as VIT, VEI) cooperation, and actively carry out electrical electrical basic research frontiers, rich design, promote technological progress. Meanwhile, the company developed for the improvement of technical means, has introduced the transformer electric and magnetic fields, short-circuit power, wave processes, the main insulation, mechanical strength and other analysis software to optimize the design for the successful development of new products provide reliable protection.

Looking ahead, the company will continue to increase R & D investment, insist on a full range, full capacity, AC and DC R & D ideas, and constantly push forward technical progress for the world and make new contributions to the development of electric power.
