This project has contributed to load reduction in the downtown area and improving the reliability of electricity supply of the power system in Ho Chi Minh City.
South Saigon - District 8 220kV transmission line is a mix of 220kV and 110kV, underground and overhead power lines. The length of the whole line is over 6.5km, connecting South Saigon 220kV substation to District 8 220kV substation, transmitting power from the Nha Be and Phu Lam 500kV substations to Phu Dinh, Chanh Hung, Hung Vuong, Tan Hung 110kV substations.
During project construction, contractors had overcome many difficulties, for example: the underground cable section on Ta Quang Buu - District 8 and Highway 50 - Binh Chanh district roads which are high traffic ones, with many existing underground works and ongoing underground projects under construction. This area is also often being inundated with sea water, which caused a lot of difficulties in site clearance.
In order to overcome these difficulties, many initiatives and solutions have been applied, most notably the design of combined PI pillar (combining 2 single steel pillars together with smaller foundation area instead of tower shaped pillar, at the same time ensuring the load capacity of pillar) was first applied on the grid of Ho Chi Minh City.
