On July 2nd, with the installation of two 220kV traction transformers in Saiyin Huduge traction substation, the 9 main transformers of Jitong Railway benhong to Menggentala section participated by China Railway Electrification Bureau were all installed in place. At this point, substation professional equipment installation into the second wiring and equipment commissioning test stage.

Traction transformer installation is the control node project of the whole traction substation construction, which is the largest equipment in volume and weight in the "four power" project behind the station, and also the core equipment of the whole traction power supply system. Its main task is to reduce the local power system 110kV/220kV high voltage voltage to 27.5kV suitable for electric locomotives, and then transfer to overhead catenary wire set up over the railway, so as to ensure the power supply of electric locomotives.

According to yu Di, the manager of the first branch of the project, during the construction process, the project department adheres to the management concept of "first piece demonstration, model lead", around the construction goal of "once in place, once into excellence", constantly optimize the construction process, and continuously promote the standardization of the site construction. In order to ensure that the construction and equipment installation of traction substation are completed on time, the project department formulated the implementation plan of "room-electricity integration" based on professional characteristics and construction procedures. The program changes the past power substation and housing construction of each major, respectively

"Since entering the site, Saiyin Huduge traction substation has been faced with many difficulties, such as rugged transportation roads for equipment and materials and limited culvert height. We are actively coordinate manufacturer, big transportation company organized field exploration, the transportation vehicles and transportation route and the way of traction transformer in place have done detailed deployment, workers at the early stage of the construction according to the height limit transportation road and culverts situation making traction transformer approach in place plan and safety assurance measures, create favorable conditions for the traction transformer in place smoothly. "It is about 500 meters from the beginning of the culvert to the institute," said Shao Wei, head of the power substation. "We have to push the culvert manually because large truck cranes cannot pass it. It takes more than four hours to pass the culvert."

Establish the construction mode of the group, reduce the cross-construction conflicts between professionals, effectively manage the interface, save the cost, shorten the construction period, and achieve the maximum economic benefit.
