Ho Chi Minh City receives completed 220kV underground power line

The 3.2km undergrounding project of the 220kV Nha Be - Tao Dan power line has been officially handed over in Ho Chi Minh City. Funded by Phu Long Group with an investment exceeding 1,000 billion VND, the project was completed in eight months, four months ahead of the original 12-month schedule.

The project covers the section from the Nha Be substation to Rach Dia Bridge. Technical complexities included using robots to drill 214 meters under the Rach Dia River and 162 meters through internal canals to ensure precision and minimize impact on waterway traffic. The infrastructure also includes 2.7km of cable trenches and ditches, along with five cable connection tunnels.

By moving the power lines underground, the project clears existing power corridors, improves the urban landscape, and creates more green space. Officials from the Ho Chi Minh City Department of Industry and Trade and Power Transmission Company 4 noted that the project supports the modern, smart, and sustainable development of the city's southern region, specifically facilitating urban renewal from Nha Be toward Can Gio.
