Hebei builds the highest-elevation railway traction transformer to pass the supervisory test

Hebei Baoding Tianwei Baochang Electric Co., Ltd. disclosed on the 25th that the world's highest altitude plateau railway, which was independently developed by the company and its subsidiary Tianwei Hefei, was built on the Qinghai-Tibet Railway from Xining to Golmud. - The (25000+25000)/110 traction transformer successfully passed the supervision of the China Railways Ministry of Product Quality Supervision and Inspection Center.

It is understood that the test items of the supervisory test include product routine tests, type tests and special tests. The test report shows that the product has good insulation performance, overload capacity, and strong ability to withstand sudden short circuits, and has small discharge loss and low loss. With low noise, it has reached the domestic advanced level. In the course of the test, the head of the Materials Division of the Electrification Bureau of the Ministry of Railways came to the scene to supervise and instruct, and highly evaluated the company's manufacturing level, management methods and quality control.

In recent years, Tianwei Baochang has continuously increased its investment in scientific research and personnel training, and its ability for independent innovation has continuously improved. It has created 750kV EHV transformers for the first time to go abroad for export to India and within 100 days to Xiangjiaba-Shanghai ±800kV UHV. The DC Transmission Demonstration Project took the lead in the production of two high-end commutation products and realized the comprehensive localization of the Three Gorges Project underground power station.
