The project includes the relocation of the 4 400KVA road lighting substation and installation of other new materials and equipment (100% new) related to the agreed quantity between the two parties, to complete the construction. At the same time, Quang Anh Electrical Construction Company Limited has converted underground cable connection columns using a 6-compartment RMU cabinet, the number of RMU compartments as required by Gia Dinh Electricity Company, with a backup of 1 compartment for Viet Shop substation.
In addition, the project also includes the construction and relocation of the 400KVA 22/0.4kV substation, installation of low voltage power supply cabinets for lighting grid and customer branches, undergrounding of 0.4kV customer branches along the road to ensure aesthetics. At the same time, the materials and equipment of the old connection pillars have been dismantled and returned to Gia Dinh Electricity Company.
The project commenced on September 16, 2022 and was completed on September 27, 2022.
Quang Anh Electrical Construction Company Limited has completed all procedures and requests for electricity supply from Gia Dinh Electricity Company until the project is electrified and put into use. The project commenced on September 16, 2022 and was completed on September 27, 2022.
