Vietnam’s rapid expansion and modernization of its energy infrastructure are key to meeting the country’s growing electricity demands and fostering continued industrial and economic growth. A significant milestone in this ongoing effort is the completion of the 500 kV Nhon Trach – Phu My – Nha Be transmission line, which was successfully finished in December 2024. This grid upgrade, crucial for enhancing the reliability and efficiency of Vietnam’s power supply, was led by the Southern Power Management Board (SPMB) under the National Power Transmission Corporation (NPT). It was designed to connect the newly established Nhon Trach Thermal Power Plant No. 4 to the national grid, making it a vital part of Vietnam’s energy future.
A Pivotal Role for ACCC Conductors
In a project of this scale, optimizing transmission efficiency and capacity was a critical objective. The 500 kV transmission line employed ACCC® Lisbon conductors, manufactured by AMP Thipha Cable. These advanced conductors are engineered for superior performance and efficiency, offering a solution for increased transmission capacity while minimizing energy loss. Using 53 kilometers of ACCC Conductor, the transmission line was constructed with steel lattice towers and features a quad-bundled configuration designed to handle the high voltage load.
A particularly challenging aspect of this project was managing an underrunning 220 kV circuit, which required precise engineering to maintain system integrity and safety. With the expertise of PECC3 (Power Engineering Consulting JSC 3) and the professional construction services of PCC2, the installation of the ACCC Lisbon conductors proceeded seamlessly, ensuring minimal disruptions and optimal efficiency.
Strategic Impact on Vietnam’s Power Grid and Energy Transition
The Nhon Trach Thermal Power Plant No. 4, which will utilize advanced GE technology, is poised to play a pivotal role in meeting the country’s growing energy needs. The integration of this power plant into the national grid via the new transmission line will enhance the reliability of electricity supply and increase overall grid capacity. The ACCC conductors, specifically chosen for their ability to handle the higher demands of this new infrastructure, are an integral part of Vietnam’s strategy to reduce transmission losses while maintaining system efficiency.
By adopting ACCC Lisbon conductors in this key transmission project, Vietnam has made a strategic investment in sustainable energy infrastructure. The new line not only connects the Nhon Trach Thermal Power Plant No. 4 to the grid but also aligns with the country’s broader energy goals, ensuring a cleaner, more resilient energy supply that will continue to support economic development.
Industry Collaboration and Future Growth
The success of this project, which was completed and energized in late December 2024, showcases the collaborative efforts of key industry players such as CTC Global, PLP, and VTD (the master installer of ACCC conductors). CTC Global’s innovative conductor technology is helping to modernize Vietnam’s grid infrastructure and improve the overall energy transmission system. As the country’s energy demand continues to rise, this transmission line represents a critical step forward in delivering a more efficient, reliable, and sustainable energy system.
In conclusion, the integration of the Nhon Trach Thermal Power Plant No. 4 with the national grid, supported by ACCC Lisbon conductors, exemplifies Vietnam’s commitment to enhancing its energy infrastructure. This landmark project not only strengthens the nation’s grid but also marks a key milestone in the transition to a more sustainable and secure energy future.
