The 750 kV, 500,000 kVA power transformers and 750 kV and 10 thousand shunt reactors identified this time are the transformers and reactors with the highest voltage class and largest capacity in China.
It is independently developed by Xichang Company through technological innovation. It has completely independent intellectual property rights and has improved the design and manufacturing level of China's power transmission and transformation equipment. Many scientific research results have guiding significance for products of 750 kV and below, and are hundreds of domestic transformers. The voltage level of 10,000 volts laid the foundation. At the same time, the certified 500 kV and 297,500 kVA converter transformers were jointly manufactured by Xichang Company and ABB Company for joint design and independent production, and were manufactured for the Three Gorges---Shanghai DC Transmission Project. Xichang Company is a domestic leader in the design and manufacture of DC transmission equipment.
At present, China's direct current transmission industry is developing rapidly. As an important part of DC transmission equipment, converter transformer has broad application prospects and will bring huge social and economic benefits. The technical performance of these three products has reached the international advanced level, which can replace foreign exchange to save foreign exchange and reduce the cost of national power construction.
The 500 kV and 167,000 kVA power transformers developed by Xichang Company for Central China Power Grid have been carefully calculated and arranged in the insulation structure in the design, thereby reducing the loss and cost of the products. The kV product has added a new variety. This time, the new products passed the identification, as well as 110 kV, 290,000 kVA power transformers, is a new generation of energy-saving transformers, and the largest transformer in the domestic 110 kV voltage class.
The high-speed construction of the national power grid has led to a sharp increase in demand for power transmission and transformation equipment, and the transformer industry has entered the fastest development period in history. Xi'an Xidian Transformer Co., Ltd. of China Xidian Group seized the historical opportunity, accelerated the speed of research and development of new products, and achieved good economic and social benefits. A few days ago, the company's five products passed the 2005 new product technology appraisal.
