Xinjiang TB high temperature superconducting power transformer turned out
Xinjiang TBEA Co., Ltd. recently announced the successful grid connection of the world's second three-phase high-temperature superconducting transformer, which also marks the first amorphous alloy core high-temperature superconducting transformer globally. After extensive testing, the device was officially put into operation in Xinjiang, representing a major milestone in power technology.
This is the first domestically developed high-temperature superconducting transformer with independent intellectual property rights in China. According to available data, the load loss of this prototype is only 4.5% of the national standard for oil-immersed transformers of similar capacity. This innovation breaks away from traditional transformer designs that have remained largely unchanged for over a century, both in terms of structure and material selection. The successful development of this technology is expected to accelerate the practical application of superconducting power systems in China, placing the country at the forefront of global research in this field.
The joint research project between Xinjiang TBEA and the Institute of Electrical Engineering, Chinese Academy of Sciences, began in 2001. Over four years, the team developed a 26 kVA three-phase high-temperature superconducting transformer. Building on this, they successfully created a 630 kVA three-phase model in November 2005, following the development of a 45 kVA single-phase prototype.
The project was carried out through an independent innovation model, addressing key technical challenges for the practical use of high-temperature superconducting transformers. It has led to multiple patents and intellectual property rights. One of the most significant innovations was the use of amorphous alloy cores, which significantly reduced both no-load and load losses, improving efficiency dramatically.
According to Zhang Xin, Chairman of Xinjiang TBEA, the new transformer is non-flammable, non-explosive, and eliminates the risk of oil leakage seen in conventional oil-immersed transformers. Additionally, it offers some ability to limit short-circuit currents. This makes it a promising alternative to traditional transformers, especially in modern power grids. With its environmental and energy-saving features, the product holds great potential for future market demand.
Superconducting technology is considered a strategic high-tech for the 21st century, with applications spanning energy, information, medical, transportation, defense, and scientific research. Its widespread adoption is expected to drive economic growth and societal progress. When combined with power technology, superconductivity could revolutionize the way electricity is transmitted, distributed, and utilized, paving the way for a more efficient and sustainable energy future.
