A Study on Improving the Rapid Assembly of Prefabricated Container-Type Substations in Cold, High-Altitude Regions

Abstract

With the development of China’s power industry, the government has been vigorously promoting the sector since the start of the 15th Five-Year Plan. There has been a significant increase in demand for prefabricated modular substations, which can shorten the construction and installation cycle of substation projects. The Nyingchi Construction Power Supply Package I project is located in Milin City at an altitude of 3,027 meters. Due to its high-altitude setting, the project faces harsh conditions such as extremely cold weather, underdeveloped infrastructure, and difficult transportation, which have posed numerous challenges to the construction of the substation. This paper primarily explores the rapid construction of prefabricated container-type substations in high-altitude areas of Tibet. Focusing on prefabricated container-type modular construction, the study analyzes the advantages of this approach in high-altitude regions, reduces on-site fabrication work, and facilitates modular manufacturing and installation. This method is environmentally friendly in the Tibetan region, minimizes the need for post-construction environmental and water restoration, and thus provides a reference for subsequent prefabricated container installation and application projects.
