On November 21, the State Grid Bortala Power Supply Company organized marketing professionals to conduct customer visits regarding the G219 Wenhuo Highway construction project, striving to ensure stable electricity supply for the construction.
The G219 Wenhuo Highway construction project is a key construction project in Northwest China’s Xinjiang Uygur Autonomous Region, starting from the southern side of Wenquan county in Bortala Mongol Autonomous Prefecture and ending in Horgos, Ili Kazakh Autonomous Prefecture.
Once completed, it will stand alongside the Duku Highway and Yizhao Highway as another popular travel route through the Tianshan Mountains, injecting strong momentum into the coordinated development of Xinjiang's tourism industry and transportation. The project emphasizes refined construction efforts and incorporates green construction technology throughout the entire process.
The Moxun Mountain Tunnel is a critical part of the Wenhuo Highway, stretching 9,300 meters and currently being the longest single-tube, bi-directional tunnel in Northwest China. The surrounding geological structure is complex, with changing climates. China Communications Second Highway Engineering Bureau Ltd. has invested in the construction of a new 110 kV Moxun Mountain Substation to provide power supply for intelligent construction equipment such as TBM tunneling machines, electric dual-head vehicles, and welding robots.
To ensure that the newly constructed power lines and substations can meet the electricity demand during peak periods of tunnel construction, the company proactively connected with users and established a dedicated flexible service team for key projects prior to commissioning. This team, composed of specialized technical personnel, conducted power load forecasts and electricity usage analyses.
They customized power supply solutions based on the varying construction intensities and equipment usage at different stages of highway development. In-depth discussions were held with the construction units regarding the scale of the substation, the capacity of the main transformer, incoming and outgoing line specifications, and other critical parameters. The team also assessed the distance from the substation to the construction area and provided guidance on technical parameters such as the length, specifications, and model of the transmission lines, ensuring stable power supply for the project.
"The Moxun Mountain Tunnel utilizes advanced TBM construction technology, incorporating clean energy as the primary power source for excavation, shotcreting, support, and muck transportation, in order to achieve green construction and reduce energy consumption and emissions," said Su Ze Yi, the project manager for the G219 Wenhuo S3 standard section of China Communications Second Engineering Bureau.
The G219 Wenhuo Highway project consumes approximately 1.6 million kilowatt-hours of electricity per month, reflecting high electricity demand and production requirements. The company closely follows user production needs by establishing dedicated electronic files to proactively monitor project electricity usage, identify potential safety hazards in electrical equipment, and provide recommendations for green construction power supply.
Currently, the Moxun Mountain Tunnel has successfully advanced 1,000 meters, marking yet another milestone towards the full completion and operation of the Wenhuo Highway, laying a solid foundation for the subsequent progress of the project.
