As of October 23, the replacement of the No. 1 main transformer at the 220 kV Shihezi West Substation, operated by the State Grid Kuitun Power Supply Company, has made significant progress. Key tasks completed include the positioning of the new transformer, installation of accessories, and vacuum extraction of the main body. Currently, the team is intensively engaged in the next phases, which involve injecting transformer oil, conducting tests, and installing three-side intervals.

The 220 kV Shihezi West Substation plays a crucial role in the regional power infrastructure, connecting to the 220 kV Shawan Substation, Silk Road Substation, Phoenix Substation, Xiayedi Substation, and Manas Power Plant. It serves as a vital link between the Tianfu power grid of the Eighth Division of the Corps and the main grid of the Xinjiang Power Grid, supplying electricity to the commercial and industrial sectors of Shihezi City.

Originally put into operation in 2009, the No. 1 main transformer has safely operated for 15 years. However, it has recently exhibited issues related to insufficient short-circuit resistance and energy efficiency.

To ensure the successful replacement of the main transformer, on-site maintenance personnel are collaborating with full-service core teams. They are strictly adhering to standard operation protocols and various construction and maintenance specifications. By leveraging the “one area, one post” approach, they are facilitating the smooth and orderly progress of the replacement work.

In parallel, the company is enhancing the management of its main equipment by transitioning from a decentralized technical supervision model to a centralized, unified management approach. The technical supervision project department has established a comprehensive work mechanism based on a “yearly plan, monthly control, and daily arrangement” system. This initiative aims to strengthen the sense of responsibility among project department members, maximize collaborative efforts, supervise the rectification of issues in a closed-loop manner, and implement an “up-down coordination” mechanism to ensure the “zero-defect” commissioning of the new equipment.
