With space reduction purpose for the installation of substations, the VISION Group has a portfolio of supply GIS (Gas Insulated Substation), which covers voltages of 72.5 kV to 550 kV.
Being a great solution for installation within large cities, the GIS is a compact substation, which has in its isolation principle the SF6 gas.
SF6 gas has a higher dielectric strength than air, providing better insulation of the equipment and reducing the distance between conductors and between owned equipment, reaching up to 60% decrease in the size of the substation in relation AIS.
Another significant feature of the GIS is low commissioning time, in addition to easy installation in temperature -50 to + 50 ° C and modular approach, which, in the case of expansion / retrofit, has low cost and time savings.
Short Delivery Time;
Short Time Commissioning;
Need little space for installation;
Quality and Reliability;
