GIS - Compact Sulfr hexafluoride Gas Insulated Substations - 69 kV to 500 kV

sf 6 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.
