Imagem principal

The VISION Group hybrid solution combines the advantages of GIS (gas insulated substation SF6) with the simplicity of the air-insulated substation, and can be found at voltage levels of 145 kV to 550 kV.

This is the most reliable and cost-effective solution for new installations, expansions or replacement of existing substations. When compared to AIS substation, reducing the area used can reach up to 50%.

Another significant feature is the low time of commissioning, easy installation further and, if Expansion / Retrofit, has low cost and time savings.
