The company has a high resonance with the development path of national railways such as conventional railways, heavy-duty railways, and high-speed railways. Since 1982, it has been developing the first electrified railway traction transformer and continuously exploring and innovating. With more than 30 years of manufacturing experience in the field of railway traction transformers, it has obvious advantages in market share, product spectrum, technical level, product performance, customer resources, etc. Its technology is leading domestically and its market share is the highest in the country. The company has carefully cultivated the railway market and has rich experience in product design, manufacturing, and service. Its main products have passed the inspection of authoritative institutions such as the Ministry of Railways. The independently developed AT power supply 220kV single-phase traction transformer, autotransformer traction transformer, Vv connection traction transformer and other products have passed the provincial new product appraisal, filling the domestic gap and reaching the international advanced level. In recent years, based on market demand, new SCOTT balanced transformers, SF6 gas insulated (GIT) traction transformers, high-temperature oil immersed flame-retardant autotransformers, new traction transformers for same phase power supply, as well as intelligent and energy-saving traction transformers have been developed successively. They have passed provincial new product appraisal, filling the domestic gap and reaching the international advanced level. The company's railway traction transformers are equipped with a number of domestic electrified railway trunk lines and high-speed railways such as Beijing Xiongyang, Beijing Zhangjiakou, Shanghai Kunming, Wuhan Guangzhou, Zhengzhou Xi'an, Coastal Expressway, Harbin Dalian, Nanjing Hangzhou, Hunan Guangxi, Daxi, Hangzhou Changsha, Guizhou Guangzhou, etc. With the the Belt and Road strategy and the high-speed railway sea going strategy, traction transformers are exported in batches to China Laos Railway, Ethiopia, Egypt, Malaysia and other electrified railway projects.
