All main structures of Yuezhou ±800 kV converter station successfully top out

The final pour of concrete for the auxiliary control building marked the successful topping out of all main structures of the Yuezhou ±800 Kilovolt Converter Station on Nov 19, laying a solid foundation for subsequent decoration, finishing, and equipment installation work.  

As a key hub of the national "West-to-East Electricity Transmission" strategy, the Yuezhou ±800 kV Converter Station serves as the "core landing point" for delivering clean energy from Gansu directly to Zhejiang. Its construction quality directly impacts the safety, stability, and efficiency of cross-regional power transmission. The main control building, acting as the station's "central nervous system", houses core functions such as operation and maintenance scheduling, system control, and equipment commissioning. This critical structure ensures the ultra-high-voltage project fulfills its role in energy resource allocation. Featuring a four-story reinforced concrete frame structure, the main control building spans a total floor area of 7,714.5 square meters with a height of 27.7 meters. Its high design standards and stringent construction requirements make it the top priority of the converter station's civil engineering works.  

Since the main construction phase commenced on Aug 1, State Grid Zhejiang Construction Company, in collaboration with State Grid Shaoxing Power Supply Company and local authorities, has established an "Engineering Construction Safety Community" to tackle multiple challenges, including prolonged rainy seasons, limited site space, and extensive cross operations. The team implemented a management mechanism characterized by "problem listing, precise measures, and accountability to individuals", along with a daily on-site coordination meeting system. By systematically addressing issues such as rain response, site planning, and process coordination — each documented and resolved — the project saw its main structures topped out within just 121 days, indicating strong progress.  

Throughout construction, Zhejiang Construction Company adhered to the core principle of "scientific and rational schedule management, meticulous quality assurance", establishing a dual-track control system for schedule and quality. For schedule control, the team reversed the overall construction plan, breaking down milestones into weekly and daily targets, with real-time progress tracking to ensure full controllability. For quality control, the team upheld the philosophy of "technology first, strict process control", rigorously enforcing drawing reviews and technical briefings. Critical processes — including raw material inspection, scaffold erection, formwork reinforcement, and concrete pouring — underwent a "triple-inspection system" to ensure compliance with design specifications and quality standards.  

Moving forward, Zhejiang Construction Company will leverage the topping out of main structures to accelerate follow-up work such as decoration, mechanical and electrical installation, and equipment commissioning in coordination with State Grid Shaoxing. The team will maintain strict oversight of safety, quality, and schedule, striving to build a benchmark ultra-high-voltage project and contribute to the company's energy supply security and high-quality grid development.
