Publication Date:2016-07-12

On June 29, Zhengzhou Hongqi 220kV Power Transmission and Transformation Project designed by Design Institute of CET was put into smooth operation with one try. The achievements of the feasibility study report were granted the first prize for Excellent Consulting Achievements by CEPPEA and the in-station layout optimization QC were awarded the first prize for Excellent QC Achievements by CEPCA. The project was delivered five months ahead of schedule.

As the largest single project in investment in Henan, the project is also the first 220kV whole-indoor intelligent substation in one building in Henan. All design indicators thereof are superior to those of projects constructed in the corresponding period and the construction area is reduced by 40% compared with the general design of SGCC. The modeling design of the substation is in good harmony and unity with its surroundings. Moreover, the complete lines of the project are developed by cable and tunnels, which stretch 9.2km in length. Constructed by shield and local mining method, the project is the first electric power tunnel developed by shield in the central and western regions and the fifth in China.
