Time:2022-06-10 11:30:07

On June 30th, the first 220kV traction substation of Nanchong Railway, which was built by The Electrification Bureau of China Railway, was successfully switched on and started, marking that the "heart" of nanchong railway traction power supply system was officially put into operation. For the next catenary electric slide to provide the prerequisite.


Traction substation, as the "heart" of nanchong Railway traction power supply system, undertakes the important task of providing direct power source for high-speed train operation. Introducing external power grid by traction transformer of 220 kv ac high voltage becomes available for high-speed emu use 27.5 kv ac high voltage, and then to the rail line above the set up of the catenary, provide kinetic energy supply, mu trains is to assure the safety of high-speed trains and high speed, reliable and stable operation of the key professional engineering.


South Chong Railway east from Nanning station, through Wuwei Airport, Fusui County to Chongzuo City. The main line is 119.29 km long with a design speed of 250 km/h. Six stations (pavilions) were designed, including three traction substations (South Chongzuo, Quli, Pingzhu) and three sub-stations (Nanning, Tanpu, Qujiounan).


In order to ensure the success of power transmission, the Nanchong Project Department of China Railway Electrification Bureau optimized the cable layout and equipment installation location in detail during the construction process of the substation, so as to ensure the quality of the project and save the installation cost to the greatest extent. At the same time, the preparation of "Flat pile traction substation opening and Starting Plan", the establishment of the power start leading group, and actively coordinate and communicate with the local power supply company, the whole process of power transmission strict norms, successfully opened the south Chong Railway traction substation power transmission and starting work.


And south railway is part of the guangxi zhuang autonomous region fully independent investment of the construction of the first high-speed railway, after the opening of guangzhou east station will implement the nanning, nanning and nanning airport train through, aircraft and high-speed seamless transfer, take the train from nanning to Wu Wei airport only 12 minutes, nanning, and to the border port cities in the left part to shorten the time from the original two hours' ride for 30 minutes.
