on september 27, xinjiang’s “hongnao three” railway electrification was officially put into operation. hongnao railway is located in hami city, xinjiang, and consists of railways from hongliu river to naomao lake and naomao lake mining area. the s14 bid project of hongnao 3rd railway constructed by china railway no. 1 electrical engineering co., ltd. has a total length of 88.12 kilometers and a total of 5 stations and 5 sections.
during the production process of the protective wall foundation pit of the catenary project, the project changed the original crane pouring method to the use of a three-wheeled small concrete transport truck and a ramp transport pulley for pouring. this not only reduced the cost of concrete tanker transportation, but also allowed it to be poured at the skylight point. it is carried out outside, which increases the effective operation time; in the power cable operation, the project completes the cable prefabrication work outside the skylight point in advance, and completes the overall assembly task inside the skylight point, which effectively improves the construction efficiency and ensures the construction quality and standardization. . due to the proper management and appropriate measures, the project successfully received power from the first 220kv traction substation on may 26; the dynamic acceptance of the catenary was successfully completed on september 8; and it successfully passed the safety assessment and other key nodes on september 21.
with the electrification put into operation, the annual transportation capacity of hongnao 3rd railway will be significantly increased from the existing 40 million tons to 60 million tons. at the same time, the train running speed will also be increased from the original 60 kilometers/hour to 80 kilometers/hour. the entire operation time will be shortened by nearly 2 hours, becoming a golden channel for "xinjiang coal export", which is of great significance to promoting regional economic development and ensuring national energy security.
