10000kVA and Above Dry-type Transformer

500kV and above ultra-high voltage and extra-high voltage power transformers, as the core equipment of modern large-capacity, long-distance, and high-efficiency power transmission and transformation systems, have always been the focus of our company's research and development. In the field of transformers with voltage levels of 500kV and above, our company has formed a systematic research system and achieved multiple results in high short-circuit resistance design, oil flow electrostatic mechanism analysis, rated capacity leakage flux calculation under high electric field environment, comparison of the impact of various coil structures on impulse performance, and the development and application of special calculation software for ultra-high voltage transformers. In addition, three-dimensional dynamic model design and three-winding simulation tests based on advanced computer software have been successfully applied to actual product design, significantly improving technical integration and product reliability. The ultra-high voltage series products produced by our company strictly follow the "three lows and one high" design and manufacturing standards, namely low loss, low noise, low partial discharge and high short-circuit resistance, fully meeting the stringent requirements of modern power systems for equipment performance. With years of accumulated experience in ultra-high voltage transformer design and manufacturing, relying on internationally leading production and testing equipment, our company ranks among the top in the national transformer industry in terms of production capacity and technical level.
