GIS - cemig nova lima 7 substation

GIS Substation (SE) 138kV Nova Lima 7


Place: Nova Lima, MG – Brazil
Value: R$ 44 millions
Beginning: 08/2013 end: 01/2017
2 km LT 138 kV Underground cable XLPE 1600 mm2
Designed for 80 MVA
104 Stakes – 300 m3 of foundation concrete
2,500 m2 of built area
4,300 m3 of earth moving

The project:

The VISION Group was supplied by turn-key using gas-insulated technology (GIS) (145 kV, 40 kA, 3150 A) and was designed for nominal capacity of 80 MVA (2 x 40 MVA).

The scope of the project includes the provision of services and equipment such as: civil works with 2,500 m2 of constructed area, 4,300 m3 of land movement, more than 2 km of insulated underground LT in 138 kV, 40 cubicles of 13.8 kV for the 3150 A and 1250 A currents and the entire substation protection and control system (SPCS).

We highlight the following benefits in this solution: decrease in delivery time, reduction of substation size, low maintenance, reduced commissioning and installation times and increased reliability.
